SereinEnv.GetFlowGlobalData("KeyName"); // 获取全局数据
SereinEnv.AddOrUpdateFlowGlobalData("KeyName", obj); // 设置/更新全局数据，不建议
~~~
* **ExpOp- 表达式节点**
* 入参: 自定义的表达式。
* 取值表达式：@Get
* 描述：有时节点返回了object，但下一个节点只需要对象中某个属性，而非整个对象。如果修改节点的定义，有可能破坏了代码的封装，为了解决这个痛点，于是增加了表达式功能。
* 使用方法：
1. 获取对象的属性成员：
~~~~
@Get .[property]/[field]
~~~~
2. 获取对象的数组成员中下标为22的项：
~~~~
@Get .array[22]
~~~~
3. 获取对象的字典成员中键为“33”的值：
~~~
@Get .dict[33]
~~~
4. 获取对象“ID”属性并转为int：
~~~
@Get .ID<int>
~~~
5. 获取KeyName为【 MyDevice 】全局数据：
~~~
@Get #MyDevice#
~~~
6. 从全局数据【 MyDevice 】中获取“IP”属性：
~~~
@Get #MyDevice#.IP
~~~
* 数据类型转换表达式：@Dtc
* 描述：有时需要显式的设置节点参数值，但参数接收了其它的类型，需要经过一次转换，将显式的文本值转为入参数据类型。
* 使用方法：
~~~
@Dtc <long>1233
@Dtc <bool>True
@Dtc <DateTime>2024-12-24 11:13:42 （注：如果右值为“now”，则自动获取当前时间）
~~~
* **ExpCondition - 条件表达式节点**
* 入参: 自定义。
* 描述：与表达式节点不同，条件表达式节点是判断条件是否成立，如果成立，返回true，否则返回false，如果表达式执行失败，而进入 error 分支。
* 使用方式：
* 入参说明：默认从上一节点获取，也可以显式设定值，也可以参考表达式节点，使用“@Get .[property]/[field]”的方式重新定义入参数据，用以条件表达式判断。
* 条件表达式：默认“PASS”，代表跳过判断直接进入下一个分支。
* 条件表达式格式“.[property]/[field]< type> [op] value”，注意，开头必须使用“.”符号，这有助于显然的表达需要从入参对象中取内部某个值。
* 表达式符号说明：
* [property] /[field] : 属性/字段
* [op] : 操作符
1. bool表达式：==
2. 数值表达式 ：==、>=、 <=、in a-b （表示判断是否在a至b的数值范围内）, !in a-b（取反）；
3. 文本表达式：==/equals（等于）、!=/notequals（不等于）、c/contains（出现过）、nc/doesnotcontain（没有出现过）、sw/startswith（开头等于）、ew/endswith（结尾等于）
* < type> ：指定需要转换为某个类型，可不选。
* [value] ： 条件值
* 使用示例：
~~~
场景1：上一个节点传入了该对象（伪代码）：
class Data
{
string Name; // 性能
string Age; // 年龄，外部传入了文本类型
string IdentityCardNumber; // 身份证号
}
需求：需要判断年龄是否在某个区间，例如需要大于18岁，小于35岁。
条件表达式：.Age<int> in 18-35
需求：需要判断是否是北京身份证（开头为”1100”）。
条件表达式：.IdentityCardNumber sw 1100
另一种方法：
入参使用表达式：@Get .IdentityCardNumber
条件表达式：sw 1100
~~~
## 3. 从DLL生成控件的枚举值：
* **Action - 动作**
* 入参：自定义。如果入参类型为IFlowContext，会传入当前的上下文；如果入参类型为IFlowNode，会传入节点对应的实体Model。如果不显式指定参数来源，参数会尝试获取运行时上一节点返回值，并根据当前入参类型尝试进行类型转换。
