Click to expand...

To change file extensions this works well

string newFilename = openFileDialog1.FileName;
newFilename = newFilename.Substring(0, filename.LastIndexOf(@".")) +
".asf";
File.Move(openFileDialog1.FileName, newFilename);
 
For some reason I thought he was just trying to change the filename as a
string...it's early here :) Combining with Arne's code, we get:

string newFilename = openFileDialog1.FileName;
File.Move( openFileDialog1.FileName,
Path.ChangeExtension(openFileDialog1.FileName, ".asf") );
