trap an event raised by a reflected dll

I have a desktop C# app.

I load a DLL dynamically.

I attach to an event.

I now want to trap the event in my app.

So, this is the DLL I am reflecting:

namespace injectdll
{
    public class Class1
    {
        public delegate void delResponseEvent(string message);
        public static event delResponseEvent ResponseEvent;
        public static void hello()
        {
            if (ResponseEvent != null)
            {
                ResponseEvent("hello andy");
            }
        }
    }
}

This is part of my desktop app:

    private void button1_Click(object sender, EventArgs e)
    {
        try
        {
            byte[] bytes = System.IO.File.ReadAllBytes(@"C:\Users\Andrew\Desktop\testbytes\injectdll\injectdll\bin\Debug\injectdll.dll");
            Assembly program = Assembly.Load(bytes);
            Type type = program.GetType("injectdll.Class1");
            var flags = BindingFlags.Static | BindingFlags.Public;
            MethodInfo Method = type.GetMethod("hello", flags);
            var eventInfo = type.GetEvent("ResponseEvent", flags);               
            type.InvokeMember("hello", System.Reflection.BindingFlags.InvokeMethod, System.Type.DefaultBinder, "", null);
        }
        catch (Exception ex)
        {

        }
    }

I now need something like this:

private void FunctionInMyDEsktopApp(string message)
{
   //this has been raised in my DLL
}
