以上是已经通过检验成功的代码,是通过递归的方式来逐个复制文件和创建文件夹.还一种方法是通过使用DOS命令行来实现的,可是不知道为什么同样的命令行,我在CMD中使用可以,在程序中就不行呢，请指教。
以下是代码: #region
//方法一:DOS命令:xcopy c:\docume~1\andy e:\andy /s/e 未实现
string s = DirectoryPath.Substring(DirectoryName(DirectoryPath));//获取文件夹名
Directory.CreateDirectory(DirAddress + "\\" + s);//创建文件夹
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = "cmd";
process.StartInfo.Arguments = "xcopy \"" + DirectoryPath + "\" \"" + DirAddress + "\\" + s + "\" /s/e";
process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
process.StartInfo.CreateNoWindow = true;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.Start();
process.WaitForExit();
#endregion
