Event-Delegate using C# to communicate between UserControl & Form

There are lots of ways to use Delegate in C#. Shown below only 2 ways of how to use Delegate to communicate between UserControl & Form.

1. Using Event-Delegate:
Inside UserControl the code will be like below:
// using event - delegate
public delegate void MyDelegate(string str);
public event MyDelegate MyEvent;

private void button1_Click(object sender, EventArgs e)
{
// event that will be fire from usercontrol & catch by form
MyEvent("SAJAL");
}

Inside Form the code will be like below:
// attach method to fire
this.userControl11.MyEvent += new UserControl1.MyDelegate(MyMethod);

void MyMethod(string str)
{
this.textBox1.Text = str;
}

2. Using Delegate:
Inside UserControl the code will be like below:
// using only delegate
public delegate void MyDelegate(string str);
public MyDelegate NewMyDelegate;

// need to store the delegate
public void FireMe(MyDelegate md)
{
NewMyDelegate = md;
}

private void button1_Click(object sender, EventArgs e)
{
NewMyDelegate("BAPPY");
}

Inside Form the code will be like below:
// attach method to fire
this.userControl11.FireMe(new UserControl1.MyDelegate(MyMethod));

void MyMethod(string str)
{
this.textBox1.Text = str;
}

The basic difference is to use an extra method for Number 2.
