How to get MIME type of file in C#

There is no direct way to get MIME type of file in C#, I have tried couple of options but didn't get any luck. though there are some WIN 32 registry and InteropServices classes from where we can get MIME type but I feel it’s too much code for getting MIME type. instead of using these classes I have found static solutions for getting MIME type, it's switch-case code for all the available MIME type based on the file extension (I know solution is not GOOD with all static file extension and MIME type)
