WPF Cancel Button

Question

I am working on a WPF Application. One of my Windows has a Button called "Cancel" with its IsCancel=true. I need to show a message box with Yes/No when the user clicks Cancel or presses ESCAPE Key. If the user click Yes, the Window should continue closing but if the user clicks No, it should not close the form but continue the regular operation with the Window opened. How can I do so? Please help. Thanks in advance.

            MessageBoxButton.YesNo, 
            MessageBoxImage.Warning);
        if (result == MessageBoxResult.No)
        {
            // If user doesn't want to close, cancel closure

                this.Close();

Open a messagebox and read the result like so:

DialogResult result = MessageBox.Show(
    "Text", 
    "Title", 
    MessageBoxButtons.YesNo,
    MessageBoxIcon.Question);

if (result == DialogResult.Yes)
{
    //The user clicked 'Yes'
}
else if (result == DialogResult.No)
{
    //The user clicked 'No'
}
else
{
    //If the user somehow didn't click 'Yes' or 'No'
}
