Trivially, whereas GetType operates on an object, typeof operates on a type. But, notice that GetType returns the underlying type of the object which can be different from the type of the reference to the object. For instance:

class BaseClass {}

 

class DerivedClass: BaseClass {}

 

class Example

{

   static void RevealType (BaseClass baseClass)

   {

      Console.WriteLine (typeof(BaseClass));

      Console.WriteLine (baseClass.GetType());

   }

 

   static void Main()

   {

      RevealType (new DerivedClass());

   }

}

gives the following output:




Example output (program output)
BaseClass
DerivedClass
