I find a similar post http://stackoverflow.com/questions/58510/using-net-how-can-you-find-the-mime-type-of-a-file-based-on-the-file-signature and it is the same result I want, I tried to use it but I received always application/octet-stream instead of video/x-flv or video/x-msvideo. I think I miss something, have you any suggest for me? Should I add some kind of information on my workspace?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
