## 2023年5月1号更新内容(做一个可编程画板):
|
||||
|
||||

|
||||
|
||||
### 1.简单使用,自定义一个text模块的代码如下:
|
||||
```
|
||||
Code = @"using System;
|
||||
namespace AIStudio.Wpf.CSharpScript
|
||||
{
|
||||
public class Writer
|
||||
{
|
||||
public string StringValue{ get; set;} = ""Welcome to AIStudio.Wpf.Diagram"";
|
||||
|
||||
public string Execute()
|
||||
{
|
||||
return StringValue;
|
||||
}
|
||||
}
|
||||
}";
|
||||
```
|
||||
是不是很简单。
|
||||
|
||||
### 2.本次扩展的主要内容
|
||||
|
||||
【1】.可编程模块,使用C#语言。
|
||||
|
||||
【2】.控制台打印控件,可以打印程序中的Console.WriteLine数据
|
||||
|
||||
【3】.为了便于大家使用,写了一个Box工厂分配Box的数据流向效果图。
|
||||
|
||||
### 3.可编程模块的实现原理
|
||||
使用Microsoft.CodeAnalysis.CSharp.Scripting对代码进行编译,生成Assembly,然后对Assembly反射获得对象,对象内部固定有一个Execute方法,每次扫描的时候执行即可。
|
||||
1.编译使用的Using,必须添加引用集,为了省事,把整个程序的Reference都放入进行编译,获得引用的核心代码如下:
|
||||
|
||||
```
|
||||
var references = AppDomain.CurrentDomain.GetAssemblies().Where(p => !p.IsDynamic && !string.IsNullOrEmpty(p.Location)).Select(x => MetadataReference.CreateFromFile(x.Location)).ToList();
|
||||
//Costura.Fody压缩后,无Location,读取资源文件中的reference
|
||||
foreach (var assemblyEmbedded in AppDomain.CurrentDomain.GetAssemblies().Where(p => !p.IsDynamic && string.IsNullOrEmpty(p.Location)))
|
||||
{
|
||||
using (var stream = Assembly.GetEntryAssembly().GetManifestResourceStream($"costura.{assemblyEmbedded.GetName().Name.ToLowerInvariant()}.dll.compressed"))
|
||||
{
|
||||
if (stream != null)
|
||||
{
|
||||
using (var compressStream = new DeflateStream(stream, CompressionMode.Decompress))
|
||||
{
|
||||
var memStream = new MemoryStream();
|
||||
CopyTo(compressStream, memStream);
|
||||
memStream.Position = 0;
|
||||
references.Add(MetadataReference.CreateFromStream(memStream));
|
||||
}
|
||||
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
2.动态编译的代码的核心代码如下:
|
||||
|
||||
```
|
||||
public static Assembly GenerateAssemblyFromCode(string code, out string message)
|
||||
{
|
||||
Assembly assembly = null;
|
||||
message = "";
|
||||
// 丛代码中转换表达式树
|
||||
SyntaxTree syntaxTree = CSharpSyntaxTree.ParseText(code);
|
||||
// 随机程序集名称
|
||||
string assemblyName = Path.GetRandomFileName();
|
||||
// 引用
|
||||
|
||||
// 创建编译对象
|
||||
CSharpCompilation compilation = CSharpCompilation.Create(assemblyName, new[] { syntaxTree }, References, new CSharpCompilationOptions(OutputKind.DynamicallyLinkedLibrary));
|
||||
|
||||
using (var ms = new MemoryStream())
|
||||
{
|
||||
// 将编译好的IL代码放入内存流
|
||||
EmitResult result = compilation.Emit(ms);
|
||||
|
||||
// 编译失败,提示
|
||||
if (!result.Success)
|
||||
{
|
||||
IEnumerable<Diagnostic> failures = result.Diagnostics.Where(diagnostic =>
|
||||
diagnostic.IsWarningAsError ||
|
||||
diagnostic.Severity == DiagnosticSeverity.Error).ToList();
|
||||
foreach (Diagnostic diagnostic in failures)
|
||||
{
|
||||
message += $"{diagnostic.Id}: {diagnostic.GetMessage()}";
|
||||
Console.WriteLine(message);
|
||||
}
|
||||
}
|
||||
else
|
||||
{
|
||||
// 编译成功,从内存中加载编译好的程序集
|
||||
ms.Seek(0, SeekOrigin.Begin);
|
||||
assembly = Assembly.Load(ms.ToArray());
|
||||
}
|
||||
}
|
||||
return assembly;
|
||||
}
|
||||
```
|
||||
3.获得编译后的程序集,以及执行。
|
||||
```
|
||||
// 反射获取程序集中 的类
|
||||
Type type = assembly.GetTypes().FirstOrDefault(p => p.FullName.StartsWith("AIStudio.Wpf")); //assembly.GetType("AIStudio.Wpf.CSharpScript.Write");
|
||||
|
||||
// 创建该类的实例
|
||||
object obj = Activator.CreateInstance(type);
|
||||
|
||||
// 通过反射方式调用类中的方法。
|
||||
var result = type.InvokeMember("Execute",
|
||||
BindingFlags.Default | BindingFlags.InvokeMethod,
|
||||
null,
|
||||
obj,
|
||||
new object[] { });
|
||||
```
|
||||
### 4.代码编辑模块的实现
|
||||
选择AvalonEdit控件,另外为了使用VS2019_Dark的黑色皮肤,引用官方Demo中的HL和TextEditlib实现自定义换肤。
|
||||
|
||||

|
||||
|
||||
官方Demo的换肤写的超级复杂,看不懂,但是我们只要理解换肤的核心部分就是动态资源字典,因此我简化下,改进后的核心换肤代码如下:
|
||||
|
||||
```
|
||||
public class TextEditorThemeHelper
|
||||
{
|
||||
static Dictionary<string, ResourceDictionary> ThemeDictionary = new Dictionary<string, ResourceDictionary>();
|
||||
|
||||
public static List<string> Themes = new List<string>() { "Dark", "Light", "TrueBlue", "VS2019_Dark" };
|
||||
public static string CurrentTheme { get; set; }
|
||||
|
||||
static TextEditorThemeHelper()
|
||||
{
|
||||
var resource = new ResourceDictionary { Source = new Uri("/TextEditLib;component/Themes/LightBrushs.xaml", UriKind.RelativeOrAbsolute) };
|
||||
ThemeDictionary.Add("Light", resource);
|
||||
|
||||
resource = new ResourceDictionary { Source = new Uri("/TextEditLib;component/Themes/DarkBrushs.xaml", UriKind.RelativeOrAbsolute) };
|
||||
ThemeDictionary.Add("Dark", resource);
|
||||
|
||||
Application.Current.Resources.MergedDictionaries.Add(resource);
|
||||
}
|
||||
|
||||
/// <summary>
|
||||

|
||||

|
||||
/// <param name="theme"></param>
|
||||
public static void SetCurrentTheme(string theme)
|
||||
{
|
||||
OnAppThemeChanged(theme);//切换到VS2019_Dark
|
||||
CurrentTheme = theme;
|
||||
}
|
||||
|
||||
/// <summary>

|
||||
/// </summary>
|
||||
internal static void OnAppThemeChanged(string theme)
|
||||
{
|
||||
ThemedHighlightingManager.Instance.SetCurrentTheme(theme);
|
||||
|
||||
if (ThemeDictionary.ContainsKey(theme))
|
||||
{
|
||||
foreach (var key in ThemeDictionary[theme].Keys)
|
||||
{
|
||||
ApplyToDynamicResource(key, ThemeDictionary[theme][key]);
|
||||
}
|
||||
}
|
||||
// Does this highlighting definition have an associated highlighting theme?
|
||||
else if (ThemedHighlightingManager.Instance.CurrentTheme.HlTheme != null)
|
||||
{
|
||||
// A highlighting theme with GlobalStyles?
|
||||
// Apply these styles to the resource keys of the editor
|
||||
foreach (var item in ThemedHighlightingManager.Instance.CurrentTheme.HlTheme.GlobalStyles)
|
||||
{
|
||||
switch (item.TypeName)
|
||||
{
|
||||
case "DefaultStyle":
|
||||
ApplyToDynamicResource(TextEditLib.Themes.ResourceKeys.EditorBackground, item.backgroundcolor);
|
||||
ApplyToDynamicResource(TextEditLib.Themes.ResourceKeys.EditorForeground, item.foregroundcolor);
|
||||
break;
|
||||

||||
case "CurrentLineBackground":
|

ApplyToDynamicResource(TextEditLib.Themes.ResourceKeys.EditorCurrentLineBackgroundBrushKey, item.backgroundcolor);
|
||||
ApplyToDynamicResource(TextEditLib.Themes.ResourceKeys.EditorCurrentLineBorderBrushKey, item.bordercolor);
|
||||
break;
|
||||
|
||||
case "LineNumbersForeground":
|
||||
ApplyToDynamicResource(TextEditLib.Themes.ResourceKeys.EditorLineNumbersForeground, item.foregroundcolor);
|
||||

|
||||
break;
|
||||
|
||||
case "Hyperlink":

||||
ApplyToDynamicResource(TextEditLib.Themes.ResourceKeys.EditorLinkTextBackgroundBrush, item.backgroundcolor);
|

|
||||
break;
|
||||
|
||||
case "NonPrintableCharacter":
|
||||
ApplyToDynamicResource(TextEditLib.Themes.ResourceKeys.EditorNonPrintableCharacterBrush, item.foregroundcolor);
|
||||
break;
|
||||
|
||||
default:
|
||||
throw new System.ArgumentOutOfRangeException("GlobalStyle named '{0}' is not supported.", item.TypeName);
|
||||
}
|
||||
}

||||
}
|
||||
|
||||
}

||||
|
||||
/// <summary>

||||
/// <param name="key"></param>

||||

|
||||
private static void ApplyToDynamicResource(ComponentResourceKey key, Color? newColor)
|
||||
{
|
||||
if (Application.Current.Resources[key] == null || newColor == null)
|
||||
return;
|
||||
|
||||
// Re-coloring works with SolidColorBrushs linked as DynamicResource
|
||||
if (Application.Current.Resources[key] is SolidColorBrush)
|
||||
{
|
||||
//backupDynResources.Add(resourceName);
|
||||
|
||||
var newColorBrush = new SolidColorBrush((Color)newColor);
|
||||
newColorBrush.Freeze();
|
||||
|
||||
Application.Current.Resources[key] = newColorBrush;
|
||||
}
|
||||
}
|
||||
|
||||
private static void ApplyToDynamicResource(object key, object newValue)
|
||||
{
|
||||
if (Application.Current.Resources[key] == null || newValue == null)
|
||||
return;
|
||||
|
||||
Application.Current.Resources[key] = newValue;
|
||||
}
|
||||
}
|
||||
```
|
||||
使用方法:
|
||||
TextEditorThemeHelper.SetCurrentTheme("VS2019_Dark");
|
||||
|
||||
或者
|
||||
TextEditorThemeHelper.SetCurrentTheme("TrueBlue");
|
||||
|
||||
或者
|
||||
TextEditorThemeHelper.SetCurrentTheme("Dark");
|
||||
|
||||
或者
|
||||
TextEditorThemeHelper.SetCurrentTheme("Light");
|
||||
|
||||
是不是超级简单。

||||

||||
|
||||

|
||||
|
||||

|
||||
|
||||
### 6.WPF打印控制台数据
|
||||
|
||||
```
|
||||
控制台打印方法支持切换运行输出方法Console.SetOut,核心代码如下:
|
||||
public class ConsoleWriter : TextWriter
|
||||
{
|
||||
private readonly Action<string> _Write;
|
||||
private readonly Action<string> _WriteLine;
|
||||
private readonly Action<string, string, string, int> _WriteCallerInfo;
|
||||
|
||||
public ConsoleWriter()

||||
{

/// <param name="writeLine">日志方法委托(针对于 WriteLine)</param>
|
||||
public ConsoleWriter(Action<string> write, Action<string> writeLine, Action<string, string, string, int> writeCallerInfo)
|
||||
{
|
||||
_Write = write;
|
||||
_WriteLine = writeLine?? write;
|
||||
_WriteCallerInfo = writeCallerInfo;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Console 输出重定向
|
||||
/// </summary>
|
||||
/// <param name="write">日志方法委托(针对于 Write)</param>

||||
/// <param name="writeLine">日志方法委托(针对于 WriteLine)</param>
|
||||
public ConsoleWriter(Action<string> write, Action<string> writeLine)
|
||||
{
|
||||
_Write = write;
|
||||
_WriteLine = writeLine;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Console 输出重定向
|
||||
/// </summary>
|
||||
/// <param name="write">日志方法委托</param>
|
||||
public ConsoleWriter(Action<string> write)
|
||||
{
|
||||
_Write = write;
|
||||
_WriteLine = write;
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// Console 输出重定向(带调用方信息)
|
||||
/// </summary>
|
||||
/// <param name="write">日志方法委托(后三个参数为 CallerFilePath、CallerMemberName、CallerLineNumber)</param>
|
||||
public ConsoleWriter(Action<string, string, string, int> write)
|
||||
{
|
||||
_WriteCallerInfo = write;
|
||||
}
|
||||
|
||||
/// <summary>

public override void Write(string value)
|
||||
{
|
||||
if (_WriteCallerInfo != null)
|
||||
{
|
||||
WriteWithCallerInfo(value);
|
||||
return;
|
||||
}
|
||||
|
||||
_Write(value);
|
||||
}
|
||||
|
||||
/// <summary>

|
||||
/// <param name="value">消息</param>
|
||||
public override void WriteLine(string value)
|
||||
{
|
||||
if (_WriteCallerInfo != null)
|
||||
{
|
||||
WriteWithCallerInfo(value);
|
||||
return;
|
||||
}
|
||||
|
||||
_WriteLine(value);
|
||||
}
|
||||
|
||||
/// <summary>
|
||||
/// 带调用方信息进行写消息
|
||||
/// </summary>
|
||||
/// <param name="value">消息</param>
|
||||
private void WriteWithCallerInfo(string value)
|
||||
{
|
||||
//3、System.Console.WriteLine -> 2、System.IO.TextWriter + SyncTextWriter.WriteLine -> 1、DotNet.Utilities.ConsoleHelper.ConsoleWriter.WriteLine -> 0、DotNet.Utilities.ConsoleHelper.ConsoleWriter.WriteWithCallerInfo
|
||||
var callInfo = ClassHelper.GetMethodInfo(4);
|
||||
_WriteCallerInfo(value, callInfo?.FileName, callInfo?.MethodName, callInfo?.LineNumber ?? 0);
|
||||
}
|
||||
|
||||
public override void Close()
|
||||
{
|
||||
var standardOutput = new StreamWriter(Console.OpenStandardOutput());
|
||||
standardOutput.AutoFlush = true;
|
||||
Console.SetOut(standardOutput);
|
||||
base.Close();
|
||||
}
|
||||
}
|
||||
```
|
||||
使用:
|
||||
|
||||
ConsoleWriter ConsoleWriter = new ConsoleWriter(_write, _writeLine);
|
||||
|
||||
Console.SetOut(ConsoleWriter);
|
||||
|
||||
### 7.动态编译模块的输入输出自动生成。
|
||||
1.输入输出模块:public string Value{ get; set;}
|
||||
2.输入模块:public string Value{private get; set;}
|
||||
3.输出模块:public string Value{get;private set;}
|
||||
4.与外部交互模块:private string Value{ get; set;} ,必须同名同属性。
|
||||
核心代码如下:
|
||||
|
||||
```
|
||||
public static Dictionary<string, List<PropertyInfo>> GetPropertyInfo(Type type)
|
||||
{
|
||||
Dictionary<string, List<PropertyInfo>> puts = new Dictionary<string, List<PropertyInfo>>()
|
||||
{
|
||||
{"Input", new List<PropertyInfo>() },
|
||||
{"Output", new List<PropertyInfo>() },
|
||||
{"Input_Output", new List<PropertyInfo>() },
|
||||
{"Inner", new List<PropertyInfo>() }
|
||||
};
|
||||
|
||||
try
|
||||
{
|
||||
foreach (System.Reflection.PropertyInfo info in type.GetProperties(BindingFlags.Public | BindingFlags.Instance))
|
||||
{
|
||||
if (info.CanRead && info.CanWrite)
|
||||
{
|
||||
if (info.SetMethod.IsPublic && info.GetMethod.IsPublic)
|
||||
{
|
||||
puts["Input_Output"].Add(info);
|
||||
}
|
||||
else if (info.SetMethod.IsPublic)
|
||||
{
|
||||
puts["Input"].Add(info);
|
||||
}
|
||||
else if (info.GetMethod.IsPublic)
|
||||
{
|
||||
puts["Output"].Add(info);
|
||||
}
|
||||
}
|
||||
else if (info.CanRead)
|
||||
{
|
||||
if (info.GetMethod.IsPublic)
|
||||
{
|
||||
puts["Output"].Add(info);
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
foreach (System.Reflection.PropertyInfo info in type.GetProperties(BindingFlags.NonPublic | BindingFlags.Instance))
|
||||
{
|
||||
if (info.CanRead)
|
||||
{
|
||||
puts["Inner"].Add(info);
|
||||
}
|
||||
}
|
||||
}
|
||||
catch (Exception ex)
|
||||
{
|
||||
|
||||
}
|
||||
|
||||
return puts;
|
||||
}
|
||||
```
|
||||
|
||||
### 8.最后介绍一下Demo的实现。
|
||||
1#.Int整数模块,界面定义一个TextBox绑定Int模块的输入管脚。
|
||||
2#.Box产生模块,如果内部数组为空,那么按照输入管脚的数量初始化一个容量为输入整数数量的数组(随机颜色与形状),然后把数据放到输出管脚,当数据被取走后,下一个数据再次放到输出管脚。
|
||||
3#.Bool模块,为false的时候按照颜色进行分配,为true的时候按照形状进行分配。
|
||||
4#.Box分配模块,当输入管脚为空的时候,2#模块的输出可以移动到4#的输入管脚,移动时间为1s,移动完成后,清除2#模块的输出。同时把数据按照颜色或者形状分配到输出,同时把输入管脚清除。
|
||||
按照颜色分配时:
|
||||
(1.如果颜色为红色,那么输出到1号
|
||||
(2.如果颜色为橙色,那么输出到2号
|
||||
(3.如果颜色为黄色,那么输出到3号
|
||||
(4.如果颜色为绿色,那么输出到4号
|
||||
(5.如果颜色为青色,那么输出到5号
|
||||
(6.如果颜色为蓝色,那么输出到6号
|
||||
(7.如果颜色为紫色,那么输出到7号
|
||||
按照形状分配时:
|
||||
(1.如果形状为圆形,那么输出到1号
|
||||
(2.如果形状为三角形,那么输出到2号
|
||||
(3.如果形状为方形,那么输出到3号
|
||||
(4.如果形状为菱形,那么输出到4号
|
||||
(5.如果形状为梯形,那么输出到5号
|
||||
(6.如果形状为五角星,那么输出到6号
|
||||
(7.如果形状为六边形,那么输出到7号
|
||||
6#.有两个红色|圆形收集器(7#,8#),按两个容器中的数量比较反馈,均匀分配到这两个收集器中。
|
||||
9#,10#,11#,12#,13#,14#按照管脚取走数据即可。
|
||||
