How to display message box in C#

In C#, a MessageBox is a pre-built dialog box used to display simple messages to the user. It's a convenient way to show alerts, confirmations, warnings, and other brief information to the user. It provides basic features like text display, buttons (OK, Yes/No, Cancel), and icons to enhance the message's clarity. The MessageBox class in the System.Windows.Forms namespace offers methods to easily create and display these dialog boxes. 

Here's the simple example.

 

MessageBox.Show( "Isn't it great ?");
