So for this article her is the code. First create a new windows application  as shown blow:

C#.Net

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using System.Collections; namespace ProjectDemo_Windows {     public partial class Form1 : Form     {         public Form1()         {             InitializeComponent();             this.button1.Click += new System.EventHandler(this.button1_Click);             this.button2.Click += new System.EventHandler(this.button1_Click);         }         private void button1_Click(object sender, EventArgs e)         {             Button _objbutton = (Button)sender;             lbmessage.Text = "You have clicked :" + _objbutton.Name;         }     } }

VB.Net

Imports System.Collections.Generic Imports System.ComponentModel Imports System.Data Imports System.Drawing Imports System.Linq Imports System.Text Imports System.Windows.Forms Imports System.Collections Namespace ProjectDemo_Windows     Partial Public Class Form1         Inherits Form         Public Sub New()             InitializeComponent()             Me.button1.Click += New System.EventHandler(AddressOf Me.button1_Click)             Me.button2.Click += New System.EventHandler(AddressOf Me.button1_Click)         End Sub         Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)             Dim _objbutton As Button = DirectCast(sender, Button)             lbmessage.Text = "You have clicked :" & _objbutton.Name         End Sub     End Class End Namespace

Her e below mention code is responsible for performing the operation

Public Sub New()             InitializeComponent()             Me.button1.Click += New System.EventHandler(AddressOf Me.button1_Click)             Me.button2.Click += New System.EventHandler(AddressOf Me.button1_Click)         End Sub
