C#.NET实现文件夹的复制

        .NET只提供了文件的Copy方法,但却没有提供文件夹的Copy方法,经过一天的努力,终于搞定.现贴出主要代码供大家参考,欢迎大家提出建议. 代码如下:

        public int DirectoryName(string DirectoryPath)//获取文件夹名，截取“\”
        {
        int j = 0;     char[] c = DirectoryPath.ToCharArray();
         for (int i = c.Length - 1; i >= 0; i--)//从后面截取
         {
        j = i;
        if (c[i] == '\\')
         {
        break;//遇"\"调处,并返回"\"的位置
         }
        }
        return j+1;
        }
        public void CopyDirectory(string DirectoryPath,string DirAddress)//复制文件夹，
         {
            #region//递归
            string s = DirectoryPath.Substring(DirectoryName(DirectoryPath));//获取文件夹名
             if (Directory.Exists(DirAddress + "\\" + s))
            {
                Directory.Delete(DirAddress + "\\" + s,true);//若文件夹存在，不管目录是否为空，删除
                 Directory.CreateDirectory(DirAddress + "\\" + s);//删除后，重新创建文件夹
            }
            else
             {
                 Directory.CreateDirectory(DirAddress + "\\" + s);//文件夹不存在，创建
            }
            DirectoryInfo DirectoryArray = new DirectoryInfo(DirectoryPath);
            FileInfo[] Files = DirectoryArray.GetFiles();//获取该文件夹下的文件列表
            DirectoryInfo[] Directorys = DirectoryArray.GetDirectories();//获取该文件夹下的文件夹列表
            foreach (FileInfo inf in Files)//逐个复制文件
            {
                File.Copy(DirectoryPath + "\\" + inf.Name, DirAddress + "\\" + s + "\\" + inf.Name);
            }
            foreach (DirectoryInfo Dir in Directorys)//逐个获取文件夹名称，并递归调用方法本身
            {
                CopyDirectory(DirectoryPath + "\\" + Dir.Name, DirAddress + "\\" + s);
            }
            #endregion
        }

        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
