Question

I want to invoke the method by the method name stored in the list. Can anyone help? I’m new to c#!

{
   delegate string ConvertsIntToString(int i);
}

class Program
{
    public static List<String> states = new List<string>() { "dfd","HiThere"};
    static void Main(string[] args)
    {
        ConvertsIntToString someMethod = new ConvertsIntToString(states[1]);
        string message = someMethod(5);
        Console.WriteLine(message);
        Console.ReadKey();
    }
    private static string HiThere(int i)
    {
        return "Hi there! #" + (i * 100);
    }
 }

It looks like you don’t need Delegate.DynamicInvoke at all – you’re not trying to invoke it dynamically – you’re trying to create the delegate dynamically, which you can do with Delegate.CreateDelegate. Short but complete program based around your example (but without using a list – there’s no need for that here):

using System;
using System.Reflection;

delegate string ConvertsIntToString(int i);

class Program
{
    static void Main(string[] args)
    {
        // Obviously this can come from elsewhere
        string name = "HiThere";

        var method = typeof(Program).GetMethod(name, 
                                               BindingFlags.Static | 
                                               BindingFlags.NonPublic);
        var del = (ConvertsIntToString) Delegate.CreateDelegate
            (typeof(ConvertsIntToString), method);

        string result = del(5);
        Console.WriteLine(result);
    }

    private static string HiThere(int i)
    {
        return "Hi there! #" + (i * 100);
    }
 }

Obviously you need to adjust it if the method you want is in a different type, or is an instance method, or is public.
