Message Box in C#

This tutorial will discuss how to create a message box with yes or no options in C#.

Create a Message Box With the MessageBox Class in C#

The MessageBox class displays a message window in C#. If we want to create a message box with yes and no options, we can pass the MessageBoxButton.YesNo enum in the parameters of the MessageBox class constructor. The following code example shows us how we can create a message box with yes and no options with the MessageBox class in C#.

using System.Windows.Forms;

namespace messagbox {
  static class Program {
    static void Main() {
      Application.EnableVisualStyles();
      DialogResult dr = MessageBox.Show("Are you happy now?", "Mood Test", MessageBoxButtons.YesNo);
      switch (dr) {
        case DialogResult.Yes:
          MessageBox.Show("That is Fantastic");
          break;
        case DialogResult.No:
          MessageBox.Show("Why Not?");
          break;
      }
    }
  }
}

Output:

In the above code, we stored the results of the MessageBox.Show() function inside the dr instance of the DialogResult enum. The DialogResult enum contains identifiers to represent the values returned by a dialog box. We used a switch statement to check the value returned by the MessageBox.Show() function and displayed another message box for each selected option.
