How to open/set the message box on web site in asp.net c#

In this article, I have pop up the message box using the code behind in c# language.

Design:-


Source code:-
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="messagebox.aspx.cs" Inherits="messagebox" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
   
        <asp:Button ID="btnmessage" runat="server" onclick="btnmessage_Click"
            Text="click here for message box" />
   
    </div>
    </form>
</body>
</html>


Code behind (C#):-
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class messagebox : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnmessage_Click(object sender, EventArgs e)
    {
        Messagebox("Welcome in Code Solution");
    }

    private void Messagebox(string Message)
    {

        Label lbMessageBox = new Label();
        lbMessageBox.Text =

            "<script language='javascript'>" + Environment.NewLine +

            "window.alert('" + Message + "')</script>";

        Page.Controls.Add(lbMessageBox);

    }
}
