Generic Methods

Generic methods have type parameters. These parameters can be used in the method header or body. An open method has type parameters, which are nonspecific. A closed method has type arguments, where specific types are substituted for type parameters. For a generic method, the type parameters are listed after the function name. The type parameter list is enclosed in angle brackets. Each parameter is comma-delimited.

Here is a sample generic method:

using System;

namespace Donis.CSharpBook {

    public class Starter {
        public static void Main() {
            ZClass.MethodA<int>(20);
        }
    }

    public class ZClass{
        public static void MethodA<T>(T param) {
            Console.WriteLine(param.GetType().ToString());
        }
    }
}

When calling a generic method, insert the type arguments ...
