Question

class TestClass
{
    public void Test()
    {
        //which is faster?
        object o1 = MethodRequiringType(typeof(TestClass));
        object o2 = MethodRequiringType(this.GetType());
        //which is better?
        //does it matter?
    }

    public object MethodRequiringType(Type t)
    {
        return new { }; 
    }
}

Answer 1

A quick google search revealed this:

GetType is a call that is made at
runtime on an instance of an object.
typeof() is resolved to a call at
runtime, but loads the type from the
token for the type. They probably
resolve to the same call, it’s just
that GetType requires an instance. If
I didn’t need the instance, I would
use typeof.

and also:

Also be aware that GetType is virtual,
and gives you the type of the object,
not the declared type of the
reference. That is:

Object o = new String();

typeof(o) Object type

o.GetType() String type
