Mouse events can be processed simply by overriding the OnMouseDown method of the Control class.

 
using System;
using System.Windows.Forms;
class MouseSample : Form {
  public static void Main() {
    Application.Run( new MouseSample() );
  }
  protected override void OnMouseDown( MouseEventArgs e ) {
    MessageBox.Show( "X:" + e.X.ToString() + " Y:" + e.Y.ToString() );
  }  
} 
   

The method OnMouseDown of the Control class expects a MouseEventArgs as argument. An object of the type MouseEventArgs has two properties X and Y for the corresponding coordinates. We use these to display the location of a mouse click.
