The object op of MethodInfo is null. You need to take care of it like this

double result = 0.0;

if (op != null)
result = (double)op.Invoke(pol, new object[] {});

Solved it!
MethodInfo was the problem here, I intentionally added new Type[] so that I can access other methods also (for separate program), the main method was forcing to get other method which is not present in the namespace.
