Change filename extension after using path.getrandomfilename

Question

1.00/5 (2 votes)

See more:

So this is my code:

My.Computer.FileSystem.RenameFile("C:\j\Application.exe", Path.GetRandomFileName())

.. The extension changes to something random, which I don't want. I want the extension to be .pdf while using the code Path.GetRandomFileName(). Can anybody help me with the right code, please?

What I have tried:

Dim myFiles As String()

myFiles = IO.Directory.GetFiles("C:\Application.exe", Path.GetExtension")

Dim newFilePath As String

For Each filepath As String In myFiles

filepath.Replace(".exe")

System.IO.File.Move(filepath, newFilePath)

Next

End Sub

End Class

Solution 1

Path.GetRandomFileName()[^] returns a string, so probably the best way to manipulate it...
If you do not care for the 8.3 format:

C#

string.Format("{0}.exe", Path.GetRandomFileName().Replace(".", string.Empty));

If the 8.3 format is important:

C#

string.Format("{0}.exe", Path.GetRandomFileName().Substring(0, 8));
