檔案移動

public static void MoveFolder(string sourcePath,string destPath)
    {
      if (Directory.Exists(sourcePath))
      {
        if (!Directory.Exists(destPath))
        {
          //目標目錄不存在則建立 
          try
          {
            Directory.CreateDirectory(destPath);
          }
          catch (Exception ex)
          {
            throw new Exception("建立目標目錄失敗：" + ex.Message);
          }
        }
        //獲得原始檔下所有檔案 
        List<string> files = new List<string>(Directory.GetFiles(sourcePath));
        files.ForEach(c =>
        {
          string destFile = Path.Combine(new string[] { destPath,Path.GetFileName(c) });
          //覆蓋模式 
          if (File.Exists(destFile))
          {
            File.Delete(destFile);
          }
          File.Move(c,destFile);
        });
        //獲得原始檔下所有目錄檔案 
        List<string> folders = new List<string>(Directory.GetDirectories(sourcePath));

        folders.ForEach(c =>
        {
          string destDir = Path.Combine(new string[] { destPath,Path.GetFileName(c) });
          //Directory.Move必須要在同一個根目錄下移動才有效，不能在不同卷中移動。 
          //Directory.Move(c,destDir); 

          //採用遞迴的方法實現 
          MoveFolder(c,destDir);
        });
      }
      else
      {
    

檔案複製

public static void CopyFilefolder(string sourceFilePath,string targetFilePath)
    {
      //獲取原始檔夾中的所有非目錄檔案
      string[] files = Directory.GetFiles(sourceFilePath);
      string fileName;
      string destFile;
      //如果目標資料夾不存在，則新建目標資料夾
      if (!Directory.Exists(targetFilePath))
      {
        Directory.CreateDirectory(targetFilePath);
      }
      //將獲取到的檔案一個一個拷貝到目標資料夾中 
      foreach (string s in files)
      {
        fileName = Path.GetFileName(s);
        destFile = Path.Combine(targetFilePath,fileName);
        File.Copy(s,destFile,true);
      }
      //上面一段在MSDN上可以看到原始碼 

      //獲取並存儲原始檔夾中的資料夾名
      string[] filefolders = Directory.GetFiles(sourceFilePath);
      //建立Directoryinfo例項 
      DirectoryInfo dirinfo = new DirectoryInfo(sourceFilePath);
      //獲取得原始檔夾下的所有子資料夾名
      DirectoryInfo[] subFileFolder = dirinfo.GetDirectories();
      for (int j = 0; j < subFileFolder.Length; j++)
      {
        //獲取所有子資料夾名 
        string subSourcePath = sourceFilePath + "\\" + subFileFolder[j].ToString();
        string subTargetPath = targetFilePath + "\\" + subFileFolder[j].ToString();
        //把得到的子資料夾當成新的原始檔夾，遞迴呼叫CopyFilefolder
        CopyFilefolder(subSourcePath,subTargetPath);
      }
    }

檔案重新命名

public ExecutionResult FileRename(string sourceFile,string destinationPath,string destinationFileName)
    {
      ExecutionResult result;
      FileInfo tempFileInfo;
      FileInfo tempBakFileInfo;
      DirectoryInfo tempDirectoryInfo;

      result = new ExecutionResult();
      tempFileInfo = new FileInfo(sourceFile);
      tempDirectoryInfo = new DirectoryInfo(destinationPath);
      tempBakFileInfo = new FileInfo(destinationPath + "\\" + destinationFileName);
      try
      {
        if (!tempDirectoryInfo.Exists)
          tempDirectoryInfo.Create();
        if (tempBakFileInfo.Exists)
          tempBakFileInfo.Delete();
        //move file to bak
        tempFileInfo.MoveTo(destinationPath + "\\" + destinationFileName);

        result.Status = true;
        result.Message = "Rename file OK";
        result.Anything = "OK";
      }
      catch (Exception ex)
      {
        result.Status = false;
        result.Anything = "Mail";
        result.Message = ex.Message;
        if (mesLog.IsErrorEnabled)
        {
          mesLog.Error(MethodBase.GetCurrentMethod().Name,"Rename file error. Msg :" + ex.Message);
          mesLog.Error(ex.StackTrace);
        }
      }

      return result;
    }
