Question

What\'s the exact difference between the two?

    // this ret         


        

Answer 1

typeof(T) returns a Type instance. and the Type is never equal to AClass

var t1 = typeof(AClass)); // t1 is a "Type" object

var t2 = new AClass(); // t2 is a "AClass" object

t2 is AClass; // true
t1 is AClass; // false, because of t1 is a "Type" instance, not a "AClass" instance
