C# Messagebox

the MessageBox.Show process is a static process, which means you do not want to generate a new MessageBox() anywhere in your code. Instead, you can basically type "MessageBox" and press the period, and then select Show. The following example shows the MessageBox.Show process used in the Form1_Load event handler. To make the Form1_Load event handler, generate a new Windows Forms application and double-click on the window in the designer.

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

        private void Form1_Load(object sender, EventArgs e)
        {
            //
            // The simplest overload of MessageBox.Show. [1]
            //
            MessageBox.Show("Dot Net Perls is awesome.");
            //
            // Dialog box with text and a title. [2]
            //
            MessageBox.Show("Dot Net Perls is awesome.",
                "Important Message");
            //
            // Dialog box with two buttons: yes and no. [3]
            //
            DialogResult result1 = MessageBox.Show("Is Dot Net Perls awesome?",
                "Important Question",
                MessageBoxButtons.YesNo);
            //
            // Dialog box with question icon. [4]
            //
            DialogResult result2 = MessageBox.Show("Is Dot Net Perls awesome?",
                "Important Query",
                MessageBoxButtons.YesNoCancel,
                MessageBoxIcon.Question);
            //
            // Dialog box with question icon and default button. [5]
            //
            DialogResult result3 = MessageBox.Show("Is Visual Basic awesome?",
                "The Question",
                MessageBoxButtons.YesNoCancel,
                MessageBoxIcon.Question,
                MessageBoxDefaultButton.Button2);
            //
            // Test the results of the previous three dialogs. [6]
            //
            if (result1 == DialogResult.Yes &&
                result2 == DialogResult.Yes &&
                result3 == DialogResult.No)
            {
                MessageBox.Show("You answered yes, yes and no.");
            }
            //
            // Dialog box that is right-aligned (not useful). [7]
            //
            MessageBox.Show("Dot Net Perls is the best.",
                "Critical Warning",
                MessageBoxButtons.OKCancel,
                MessageBoxIcon.Warning,
                MessageBoxDefaultButton.Button1,
                MessageBoxOptions.RightAlign,
                true);
            //
            // Dialog box with exclamation icon. [8]

            MessageBox.Show("Dot Net Perls is super.",
                "Important Note",
                MessageBoxButtons.OK,
                MessageBoxIcon.Exclamation,
