关闭窗口不止一次 [英] Closing window is occurring more than one time

问题描述

多次关闭窗口发生



我尝试过：

Multiple times closing window occurring

What I have tried:

private void Form2_FormClosing(object sender, FormClosingEventArgs e)
{
    DialogResult d = MessageBox.Show("Do u want to close application", "Exit", MessageBoxButtons.YesNo);
    if (d == DialogResult.Yes)
    {
        Application.Exit();
    }
    else if(d==DialogResult.No)
    {
        e.Cancel = true;
    }
}

推荐答案

调试将解释原因...设置断点 Form2_FormClosing 事件，每次到达断点时都会查看堆栈跟踪，您会看到原因。

Debugging will explain why... Set a breakpoint in the Form2_FormClosing event, look at the stack trace each time you hit the breakpoint and you will see why.
