title: Can I find a file by filename only (i.e. extension unknown)
body: <p>We have a network folder that is the landing place for csv files processed by different servers.  We alter the extension of the csv files to match the server that processed the file; for instance a file with the name <code>FooBar</code> that was process by Server1 would land in the network share with the name <code>FooBar.Server_1</code>.  </p>
  
  <p>The information I have available to to me is file name: <code>FooBar</code> and the path to the share.  I am not guaranteed the extension as there are multiple servers sending csv files to the network share.  I am guaranteed that there will only be one <code>FooBar</code> file in the share.  </p>
  
  <p>Is there a method in .net 2.0 that can be used to get the extension of the csv armed only with the path and filename?  Or do I need to craft my own?</p>
