Why doesn't C# switch statement allow using typeof/GetType()?

Question

As in this example:

switch ( myObj.GetType ( ) )
{
    case typeof(MyObject):
        Console.WriteLine ( \"MyObject is here\" );
        break;
}
         


        

Answer 1

I would add to Peter's excellent analysis the following thought:

Fundamenatally, the purpose of a "switch" is to choose one of some number of distinct possibilities. A given value of enum, integer, Boolean or string type can only be one value, so it makes sense to "switch" on such a value. But types are fundamentally different. A given value usually has many types. Types frequently overlap. The proposed "type switch" does not match the stated purpose of the switch construct.
