changing a filename in C#

I can't seem to find any resources to help me change a filename using C#. I
see a Path.ChangeExtension, but it only takes the full path as a string and
changes that string. It doesn't actually change the file (at least not from
what I have seen). I tried moving the file into the same directory with a
different name and totally lost my file. I am about to try moving it to
another directory and then moving it back with the new name. All I really
want to do is change the extension on the file from .tmp to .txt. Can
someone tell me how I can use C# code to change the name of a file. I
apologize if this is too elementary for this news group.

Thanks for your help,

JML
 
FileInfo original = new FileInfo(pathToFile);
if ( original.Exists ) {
// If the destination already exists then this won't copy.
// This is to protect other files when performing the operation.
original.CopyTo(Path.ChangeExtension(original.FullName, ".txt"), false);
}

Have a look at File.Move.
 
I tried File.Move, but couldn't get it to work right for some reason. Maybe
my path was wrong. Thanks for the reply though.
 
Hi Marshall,

Jeffery,

I actually got it to work with the File.Move. I move it to a different
directory and then I move it to the desired directory with the new name. I
haven't had a chance to try what you and Justin were talking about. Sorry
about that. And thanks for the advice.
