如何覆盖Windows窗体中的关闭控件c＃ [英] How to override closing control in Windows Form c#

问题描述

在form1中，我得到了：

  private void button1_Click（object sender，EventArgs e）
 {
 Form2 form2 = new Form2（）; 
 form2.Tag = this; 
 form2.Show（this）; 
 Hide（）; 
} 
  

然后当我点击XI时想显示前一个并隐藏当前。

解决方案

您可以覆盖

  
 
保护覆盖无效OnFormClosing（FormClosingEventArgs e）
 {
 if（e.CloseReason == CloseReason.WindowsShutDown）return; 
 
 //在此处进行
} 
  

I would like to make X control closing window to hide current display previous form.

In form1 I got:

private void button1_Click(object sender, EventArgs e)
{
    Form2 form2 = new Form2();
    form2.Tag = this;
    form2.Show(this);
    Hide();
}

and then when I click X I would like to show previous and hide the current.

解决方案

You can override OnFormClosing to do this.

 protected override void OnFormClosing(FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.WindowsShutDown) return;

    // DO WHATEVER HERE
}
