Use type parameters as constraints on generic classes in scenarios in which you want to enforce an inheritance relationship between two type parameters. This constraint applies also to any class, interface, delegate, or array type.
GetType with typeof T. Upcoming Events. The preceding method must be compiled in an unsafe context because it uses the sizeof operator on a type not known to be a built-in type.

The following figure illustrates how the compiler will replace T with int in MyGenericClass. In both cases, the body of the method can safely rely on knowledge that arg is of or is a descendant of a specific type that is known at compile time.
Usually, you want to keep your type generic inside your method no casting, no braching based on type , something like this: Both first and test are delegate types, but they are different delegate types.
The compiler can only assume the members of Object , which is the ultimate base class for any.
You may also leave feedback directly on GitHub. Now, the compiler assigns the type based on the type passed by the caller when instantiating a class.
