Checking if a file is in use without try catch?

Question

Is there a way I can check if a file is in use or is not opened by other process without just trying to open it and catching an exception? Is there no service method to test

You could implement this guy in .net 4.5 but it includes a lot of overhead http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx
