C # code for renaming a file,

In C #, there is no rename method. I wrote a method to process file rename.

/// <Summary>

/// Rename all subfolders in the folder

/// </Summary>

/// <Param name = "directoryName"> folder name </param>

/// <Param name = "newDirectoryName"> New subfolder name Format String </param>

Public void RenameDirectories (string directoryName, string newDirectoryName)

{

Int I = 1;

String [] sDirectories = Directory. GetDirectories (directoryName );

Foreach (string sDirectory in sDirectories)

{

String sDirectoryName = Path. GetFileName (sDirectory );

String sNewDirectoryName = string. Format (newDirectoryName, I ++ );

String sNewDirectory = Path. Combine (directoryName, sNewDirectoryName );

Directory. Move (sDirectory, sNewDirectory );

}

}

 

 

// Full path name of the original file in the list
String oldStr = ft. FileRoute + @ "/" + ft. FileName + ft. ExName;

// New file name
String newStr = ft. FileRoute + @ "/" + preChar + name + nextChar + ft. ExName;

// Rename Method
FileInfo fi = new FileInfo (oldStr );
Fi. MoveTo (Path. Combine (newStr ));
