How to Popup A Message in C#

This tutorial will discuss the method of displaying a popup message window in C#.

Display Popup Message With the MessageBox Class in C#

If we have a button and want to show a popup message when the button is clicked, we can use the MessageBox class in C#. The MessageBox.Show() method displays a message window on-screen in C#. The MessageBox.Show() method takes the message in the string format as an input parameter and displays it to the user. The following code example shows us how to create a simple popup message window that shows some message in response to a button click with the MessageBox.Show() method in C#.

using System;
using System.Windows.Forms;

namespace popup {
  public partial class Form1 : Form {
    public Form1() {
      InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e) {
      string text = "This is some Text that I wanted to show";
      MessageBox.Show(text);
    }
  }
}

Output:

In the above code, we created a popup message window that gets shown each time the button1 is clicked by the user with the MessageBox.Show() function in C#.
