This is a story of two types: GenericType and SpecificType, where GenericType is a superclass of SpecificType. There are two types of explicit cast in C#:

Most programmers have a habit of using one or the other - this isn't usually a conscious decision, but more of a function of which form a programmer saw first. I, for instance, programmed in Java before I learned C#, so I was already in the prefix cast habit. People with a Visual Basic background often do the opposite. There are real differences between the two casting operators which can make a difference in the reliability and performance of your application.
