How to get the typeof(T) from a generic method with base type constraint?

Question

I have the following spec to help illustrate the problem:

class when_getting_type_of_generic_argument_using_subtype_instance
{
    static GenericTypeTester _gene         


        

Answer 1

Just add the constrait "class" to your method :

 class GenericTypeTester
 {
   public Type Test(T dog) where T : IPet, class
   {
     return typeof (T);
   }
 }
