How can I occure a method in C# "returning a methods"

public void Invoke<T>(string methodName) where T : new()
{
    T instance = new T();
    MethodInfo method = typeof(T).GetMethod(methodName);
    method.Invoke(instance, null);
}

using System.Reflection;
namespace linqpractice
{

  class MyClass
    {

        public static int method1()
        {
            return 1;
        }
        public static string method2()
        {
            return "Hello";
        }
        public static double method3()
        {
            return 1.5;
        }
    }
 class Program
    {
      
        static void Main(string[] args)
        {


            //linqpractice namespace
            //MyClass is the class where method1(),method2() and method3() are present
            Type calledType = Type.GetType("linqpractice.MyClass");
            ArrayList ob = new ArrayList();
            for (int i = 1; i <= 3; i++)
            {
                ob.Add(calledType.InvokeMember(
                             "method" + i.ToString(),
                             BindingFlags.InvokeMethod | BindingFlags.Public |
                                 BindingFlags.Static,
                             null,
                             null,
                             null));

            }
            //printing the returns value of the methods
            foreach (var item in ob)
            {
                Console.WriteLine(item); 
            }
            
           
        }
    }
