c#实现复制全部文件夹及文件的代码

代码如下：

private void Copy()
{

  System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo("D:\\data");
  CopyDirectorysAndFiles("c:\\", dir);

}

private void CopyDirectorysAndFiles(string dest, System.IO.DirectoryInfo srcdir)
{
  if (dest.LastIndexOf('\\') != (dest.Length - 1))
  {
    dest += "\\";
  }
  string destPath = dest + srcdir.Name + "\\";
  if (!System.IO.Directory.Exists(destPath))
  {
    System.IO.Directory.CreateDirectory(destPath);
  }

  System.IO.FileInfo[] files = srcdir.GetFiles();
  foreach (System.IO.FileInfo file in files)
  {
    file.CopyTo(destPath+file.Name , true);
  }

  System.IO.DirectoryInfo[] dirs = srcdir.GetDirectories();
  foreach (System.IO.DirectoryInfo dirInfo in dirs)
  {
    CopyDirectorysAndFiles(destPath , dirInfo);
  }
}

欢迎建议!
