Typeof() vs GetType()

 GetType():
====================
if you want to obtain the type from an instance of your class,you can use GetType().

GetType() returns run time type of the instance.

TypeOf():
===============
if you don't have an instance,but you know the type name,you would use typeof().

TypeOf() gives the compile time of class.

Note :
=====
Operator TypeOf(ClassName) is used to obtain the System.Type object for a Type at compile time.

MyObject.GetType() is used to obtain the exact run time type of object.This method uses reflection.
