Answer 1

declarations of variable is compile time only information whereas method execution is runtime. In other words there's no way GetType() can know what type the object was declared as it can only know the actual type of the object at runtime.

similar if you had

class a
{
}

class b : a

a bInstance = new b();
bInstance.GetType();

the call to bInstance.GetType() have no way of knowing that the variable was declared as type 'a' and I don't think you expect it to return 'a' in this case either. However in the example above a is my abbreviation of object and b is for System.Int32
