1. 扫描目录并计算哈希

2. 将重复文件压缩并保存
|

|
||
|
||
var manifest = new List<FileRecord>();
|

|
||
ArchiveFile = $"{hash}.gz",
|
||
OriginalPaths = kvp.Value
|
||
});
|
||
}
|
||
|
||
3. 生成清单文件（JSON）
|
||
public class FileRecord
|
||
{
|
||
public string Hash { get; set; }
|
||
public string ArchiveFile { get; set; }
|
||
public List<string> OriginalPaths { get; set; }
|
||
}
|
||
|
||
File.WriteAllText("manifest.json", JsonSerializer.Serialize(manifest, new JsonSerializerOptions { WriteIndented = true }));
|
||
|
||
|
||
4. 根据清单还原原始文件结构
|
||
var manifestJson = File.ReadAllText("manifest.json");
|
||
var manifest = JsonSerializer.Deserialize<List<FileRecord>>(manifestJson);
|
||
|
||
foreach (var record in manifest)
|
||
{
|
||
var archivePath = Path.Combine("compressed_output", record.ArchiveFile);
|
||
|
||
foreach (var path in record.OriginalPaths)
|
||
{
|
||
Directory.CreateDirectory(Path.GetDirectoryName(path)!);
|
||
|
||
using var input = File.OpenRead(archivePath);
|
||
using var gzip = new GZipStream(input, CompressionMode.Decompress);
|
||
using var output = File.Create(path);
|
||
|
||
gzip.CopyTo(output);
|
||
}
