Here is asp.net we do not have direct message box like windows forms but have confirmatation box or alerts message or popups using javascripts
Simple MessageBox functionality in ASP.NET[^]
ASP.NET MessageBox[^]
ASP.Net Message Box Alert Display[^]
here is simple example using javascript:

XML

<html>
 <head>
 <script>
 function display_alert()
   {
   alert("Hello! I am an alert box!!");
   }
 </script>
 </head>
 <body>

<input type="button" onclick="display_alert()" value="Display alert box">

</body>
 </html>

hope it helped

Happy Coding!!

C#

System.Windows.Forms.MessageBox.Show

is for Windows forms not web forms

You can instead display an alert using javascript alert like

C#

Response.Write("<script type='text/javascript'> alert('your message here.')</script>");

This is possible in web forms also,
try,
put namespace on starting using System.Windows.Forms; then
use Message.show("");

There is no direct suport for message box in asp.net. One alternative is you can use javascript to display an alert.
