For a method to qualify as an eventhandler, it must have object sender and e eventargs as parameters. f.e.:

form1.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.Form1_FormClosing);
...

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
   e.Cancel = true;
   MessageBox.Show("test");
}

Visual Studio can't evaluate this, can you? public object moo { __get { return moo; } __set { moo = value; } }

Hello I want to change this method public void Onclickadd() { int result = int.Parse(num1.Text) + int.Parse(num2.Text); MessageBox.Show(result.ToString()); } So that it can be used by predefined "Click" event. How?
