How Do I Rename a File in C#?

C# File Renaming Made Easy

Renaming files in C# is simple using the System.IO.File.Move method. This method effectively renames a file by moving it to a new location with a different name.

Here's how it works:

<code class="language-csharp">System.IO.File.Move("oldfilename", "newfilename");</code>

Replace "oldfilename" with the existing file's name and "newfilename" with the desired new name. The method handles the renaming process directly.

This approach is more efficient than deleting the original file and creating a new one. However, be aware that File.Move will overwrite any file already existing with the "newfilename".
