推荐答案

private void Main_FormClosing(object sender, FormClosingEventArgs e)
{
    if (MessageBox.Show("Are you sure you want to close the application?",
        "Close?", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
    {
        e.Cancel = true;
    }
}

现在，您只需开发一个具有三个按钮的新表单，即可返回DialogResult.Yes，DialogResult.No和DialogResult.Cancel.

将上面的代码中的MessageBox.Show替换为调用您的自定义窗口的代码.

Now you only have to develop a new form with three buttons, that returns a DialogResult.Yes, DialogResult.No and a DialogResult.Cancel.

Replace the MessageBox.Show in the above code with code that calls your custom window.
