虽然退出表格我必须点击两次是消息框的按钮 [英] While Exit Of The Form I Have To Click Two Times Yes Button Of Message Box

问题描述

private void Admin_FormClosing(object sender, FormClosingEventArgs e)
{
    DialogResult dialog = MessageBox.Show("Do you really want to close the      Program?", "Exit", MessageBoxButtons.YesNo);
    if (dialog == DialogResult.No)
    {
        e.Cancel = true;


    }
    else if (dialog == DialogResult.Yes)
    {

        e.Cancel = false;
        Application.Exit();
    }
}

推荐答案

取出'else子句：你的调用Application.Exit正在获取猴子confused。

Take out the 'else clause: your calling Application.Exit is getting the monkey confused.

private void Admin_FormClosing(object sender, FormClosingEventArgs e)
{
    DialogResult dialog = MessageBox.Show("Do you really want to close the      Program?", "Exit", MessageBoxButtons.YesNo);
    
    if (dialog == DialogResult.No) e.Cancel = true;
}
