c# event handling between two forms

Question

I have two forms and I am trying to capture an event generated from frmEventGenerate.cs in frmEventReceive.cs.

In this example I can receive the event from frmEven

Answer 1

//Receiver

using System;
using System.Windows.Forms;

namespace eTest
{
    public partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
        }

        public void ReceiveEvent(int i)
        {
            MessageBox.Show("Event Received from Form: " + i.ToString());
        }

        private void btnNew_Click(object sender, EventArgs e)
        {
            int num = 0;
            int x = 0;

            num = Convert.ToInt32(txtForms.Text);

            for (x = 0; x < num; x++)
            {
                frmDL f = new frmDL();
                f.Evt += ReceiveEvent;
                f.iID = x;
                f.Text = x.ToString(); 
                f.Show();
                f.Activate();
                Application.DoEvents();
            }
        }
    }
}

//Sender

using System;
using System.Windows.Forms;

namespace eTest
{
    public delegate void myEventHandler(int i);

    public partial class frmDL : Form
    {
        public event myEventHandler Evt;

        public int iID = 0;

        public frmDL()
        {
            InitializeComponent();
        }

        public void SendEvent()
        {
            if (Evt != null)
            {
                Evt(this.iID);
            }
        }

        private void btnEvent_Click(object sender, EventArgs e)
        {
            SendEvent();
        }
    }
}

Answer 2

In your constructor, after instantiating frmEventGenerate:

frmGen.Evt += ReceiveEvent;

You don't need new LinkEventHandler(...) any more - as of C# 2, there's a method group conversion available which you can use to convert from a method group (the name of a method) to a delegate type.

EDIT: I hadn't seen that your event was static. That suggests you should actually use:

frmEventGenerate.Evt += ReceiveEvent;

... and you don't need the frmGen variable at all.

However, I would strongly discourage you from this - why do you want the event to be static in the first place? (I'd also urge you to name your types more sensibly - something like "EventGenerator" would be better here, for example. Ignoring the convention that type names should be in Pascal case leads to confusing code.)
