When I open a file, I want to know if it is being used by another process so I can perform special handling; any other IOException I will bubble up. An IOException's Message property contains "The process cannot access the file 'foo' because it is being used by another process.", but this is unsuitable for programmatic detection. What is the safest, most robust way to detect a file being used by another process?
