C#.NET實(shí)現文件夾的復制 

2008-07-03
      .NET只提供了文件的Copy方法,但卻沒(méi)有提供文件夾的Copy方法,經(jīng)過(guò)一天的努力,終于搞定.現貼出主要代碼供大家參考,歡迎大家提出建議. 代碼如下:         public int DirectoryName(string DirectoryPath)//獲取文件夾名，截取“\”
        {
        int j = 0;     char[] c = DirectoryPath.ToCharArray();
         for (int i = c.Length - 1; i >= 0; i--)//從后面截取
         {
        j = i;
        if (c[i] == '\\')
         {
        break;//遇"\"調處,并返回"\"的位置
         }
        }
        return j+1;
        }

 

        public void CopyDirectory(string DirectoryPath,string DirAddress)//復制文件夾，
         {
            #region//遞歸 

            //獲取文件名方法一：用上函數
            //string s = DirectoryPath.Substring(DirectoryName(DirectoryPath));//獲取文件夾名

            //獲取文件名方法二：用string類(lèi)的LastIndexOf()和Substring()函數

               int index = DirectoryPath.LastIndexOf('\\');
             string s=DirectoryPath.Substring(index+1);

             if (Directory.Exists(DirAddress + "\\" + s))
            {
                Directory.Delete(DirAddress + "\\" + s,true);//若文件夾存在，不管目錄是否為空，刪除
                 Directory.CreateDirectory(DirAddress + "\\" + s);//刪除后，重新創(chuàng )建文件夾
            }
            else
             {
                 Directory.CreateDirectory(DirAddress + "\\" + s);//文件夾不存在，創(chuàng )建
            }
            DirectoryInfo DirectoryArray = new DirectoryInfo(DirectoryPath);
            FileInfo[] Files = DirectoryArray.GetFiles();//獲取該文件夾下的文件列表
            DirectoryInfo[] Directorys = DirectoryArray.GetDirectories();//獲取該文件夾下的文件夾列表
            foreach (FileInfo inf in Files)//逐個(gè)復制文件
            {
                File.Copy(DirectoryPath + "\\" + inf.Name, DirAddress + "\\" + s + "\\" + inf.Name);
            }
            foreach (DirectoryInfo Dir in Directorys)//逐個(gè)獲取文件夾名稱(chēng)，并遞歸調用方法本身
            {
                CopyDirectory(DirectoryPath + "\\" + Dir.Name, DirAddress + "\\" + s);
            }
            #endregion
        }
