Renaming a directory in C# [closed]

Question

I couldn't find a DirectoryInfo.Rename(To) or FileInfo.Rename(To) method anywhere. So, I wrote my own and I'm posting it here for anybody to use if they need it, because let's face it : the MoveTo methods are overkill and will always require extra logic if you just want to rename a directory or file :

public static class DirectoryExtensions {     public static void RenameTo(this DirectoryInfo di, string name)     {         if (di == null)         {             throw new ArgumentNullException("di", "Directory info to rename cannot be null");         }          if (string.IsNullOrWhiteSpace(name))         {             throw new ArgumentException("New name cannot be null or blank", "name");         }          di.MoveTo(Path.Combine(di.Parent.FullName, name));          return; //done     } } 

Answer 1

There is no difference between moving and renaming; you should simply call Directory.Move.

In general, if you're only doing a single operation, you should use the static methods in the File and Directory classes instead of creating FileInfo and DirectoryInfo objects.

Answer 2

You should move it:

Directory.Move(source, destination);
