I have a class

public class A<T>
{
   public static string B(T obj)
   {
       return TransformThisObjectToAString(obj);
   }
}

I can call the static function like this just fine on a known/specified type:

string s= A<KnownType>.B(objectOfKnownType);

How do I make this call, if I don't know T beforehand, rather I have a variable of type Type that holds the type. If I do this:

Type t= typeof(string);
string s= A<t>.B(someStringObject);

I get this compiler error:

Cannot implicitly convert type 't' to 'object'
