点击一下关闭两个表单？ [英] Close two form by one click?

问题描述

我正在使用登录功能进行项目工作

当我运行项目时，有一个窗体（ form1 ）运行登录。
之后，我点击登录按钮建立另一个表单（ form2 ） - 这是我的程序的形式。
并将第一个表单（ form1 ）隐藏起来。

问题是当我按下在form2中的X按钮它是关闭的，但form1仍然在运行。

我试图关闭 form1 ，而不是隐藏...但这会在启动前关闭 form2 $ b $ form1

  this.Hide（）; 
 Form2 x = new Form2（）; 
 x.Show（）; 
  

解决方案

您可以订阅子表单 FormClosed 事件并用它在父窗体上调用 Close 。

  x.FormClosed + = new FormClosedEventHandler（x_FormClosed）; 
 
 void x_FormClosed（Object sender，FormClosedEventArgs e）
 {
 this.Close（）; 
} 
  

I'm working on project with sign in feature

When I run the project there is a form (form1) run the sign in . after i click on login button build another form (form2) - It's the form of my program . and made the first form (form1) hide .

The problem is when I press at the X button in form2 it's close but the form1 it's still running .

I tried to close the form1 instead of hide ... but this will close form2 before launching

In form1:

this.Hide();
Form2 x = new Form2();                 
x.Show();

解决方案

You could subscribe to the child forms FormClosed event and use that to call Close on the parent form.

x.FormClosed += new FormClosedEventHandler(x_FormClosed);

void x_FormClosed(object sender, FormClosedEventArgs e)
{
    this.Close();
}
