This article mainly introduces how to operate C# files (move, copy, rename), helping everyone better understand and use C#. Interested friends can learn about it

File movement

public static void MoveFolder(string sourcePath, string destPath)
    {
      if ((sourcePath))
      {
        if (!(destPath))
        {
          //Create the target directory if it does not exist          try
          {
            (destPath);
          }
          catch (Exception ex)
          {
            throw new Exception("Creating the target directory failed:" + );
          }
        }
        //Get all files under the source file        List&lt;string&gt; files = new List&lt;string&gt;((sourcePath));
        (c =&gt;
        {
          string destFile = (new string[] { destPath, (c) });
          //Coverage mode          if ((destFile))
          {
            (destFile);
          }
          (c, destFile);
        });
        //Get all directory files under the source file        List&lt;string&gt; folders = new List&lt;string&gt;((sourcePath));

        (c =&gt;
        {
          string destDir = (new string[] { destPath, (c) });
          //It must be moved in the same root directory to be effective, and it cannot be moved in different volumes.          //(c, destDir); 

          //Use recursive method to implement          MoveFolder(c, destDir);
        });
      }
      else
      {

File Copy

public static void CopyFilefolder(string sourceFilePath, string targetFilePath)
    {
      //Get all non-directory files in the source folder      string[] files = (sourceFilePath);
      string fileName;
      string destFile;
      //If the target folder does not exist, create a new target folder      if (!(targetFilePath))
      {
        (targetFilePath);
      }
      //Copy the obtained files to the target folder one by one      foreach (string s in files)
      {
        fileName = (s);
        destFile = (targetFilePath, fileName);
        (s, destFile, true);
      }
      //The above paragraph can be seen on MSDN
      //Get and store the folder name in the source folder      string[] filefolders = (sourceFilePath);
      //Create Directoryinfo instance      DirectoryInfo dirinfo = new DirectoryInfo(sourceFilePath);
      //Get all subfolders in the source folder      DirectoryInfo[] subFileFolder = ();
      for (int j = 0; j &lt; ; j++)
      {
        //Get all subfolder names        string subSourcePath = sourceFilePath + "\\" + subFileFolder[j].ToString();
        string subTargetPath = targetFilePath + "\\" + subFileFolder[j].ToString();
        //Recall the obtained subfolder as a new source folder and call CopyFilefolder recursively        CopyFilefolder(subSourcePath, subTargetPath);
      }
    }

File renaming

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 (!)
          ();
        if ()
          ();
        //move file to bak
        (destinationPath + "\\" + destinationFileName);

         = true;
         = "Rename file OK";
         = "OK";
      }
      catch (Exception ex)
      {
         = false;
         = "Mail";
         = ;
        if ()
        {
          (().Name, "Rename file error. Msg :" + );
          ();
        }
      }

      return result;
    }
