How To Restart Exe.Project in c#

An important question ask here is: Why do you want to restart the Application when it is your own code that closes (evidently) the Main Form which (in a WinForm app) terminates the Application ?

Why close the Application/Form if you want to keep it "alive" ?

Why not do something like write an EventHandler for the Main Form 'Closing Event: and give the user the choice to quit the Application, or keep going ?

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if (
        MessageBox.Show(
        "Quit the Application ?",
        "Do you really want to quit ?",
        MessageBoxButtons.YesNo,
        MessageBoxIcon.Warning,
        MessageBoxDefaultButton.Button2)
        == DialogResult.No)
    {

        e.Cancel = true;
    }
}
