c# - 将 LastWriteTime 设置为解压缩文件的原始时间戳

Question

我正在使用 Sharpziplib 版本 0.86.0 来提取 zip 文件。它工作正常，但提取的文件使用当前日期时间。我怎样才能得到原来的日期时间？

public static void UnzipFile(string sourcePath, string targetDirectory)
{
  try
  {
    using (ZipInputStream s = new ZipInputStream(File.OpenRead(sourcePath)))
    {
      ZipEntry theEntry;
      while ((theEntry = s.GetNextEntry()) != null)
      {
        //string directoryName = Path.GetDirectoryName(theEntry.Name);
        string fileName = Path.GetFileName(theEntry.Name);

        if (targetDirectory.Length > 0)
        {
          Directory.CreateDirectory(targetDirectory);
        }

        if (fileName != String.Empty)
        {
          using (FileStream streamWriter = File.Create(targetDirectory + fileName))
          {
            int size = 2048;
            byte[] data = new byte[2048];
            while (true)
            {
              size = s.Read(data, 0, data.Length);
              if (size > 0)
              {
                streamWriter.Write(data, 0, size);

              }
              else
              {
                break;
              }
            }
          }
        }
      }
    }
  }
  catch (Exception ex)
  {
    throw new Exception("Error unzipping file \"" + sourcePath + "\"", ex);
  }
}

每个都ZipEntry应该有一个DateTime包含文件最后修改日期的时间戳的属性。

尝试将此值与File.SetLastWriteTime.
