C# Question: File Names
<p>I have a file called o.FileName it has a unwanted ".crash" at the end of it, how can I remove it?  I tryed "o.FileName = o.FileName - ".crash";" it didn't work because it was a string</p>

<p>Edit: What I want to do is open a file with a OpenFileDialog then if it has a .crash or a .crash.crash at the end of it remove it and save it </p>
