如何同时关闭两个表格？ [英] How to close two forms at the same time?

问题描述

我有3种形式： Form1 ， Form2 ， Form3 。



当您在 Form1 上单击 buttonPlay 时， Form2 pops起来。当您点击 Form2 上的 button1 时， Form1 和 Form2 应该关闭， Form3 会弹出。



这是我在按钮1 的点击事件 Form2 上的代码：

I have 3 forms: Form1, Form2, Form3.

When you click on buttonPlay on Form1, Form2 pops up. When you click on button1 on Form2, both Form1 and Form2 are supposed to close and Form3 will pop up.

This is my code on Form2 on the Click event of button1:

private void button1_Click(object sender, EventArgs e)
        {


            Form1 x = new Form1();
            //SUPPOSEDLY hides Form1
            x.Hide();


            //Hides Form2
            this.Hide();


            Form3 f3 = new Form3();
            //Shows Form3
            f3.Show();

        }

我试过关闭（）和 Dispose（）并使用< identifier> .Visible = false; 并且没有人工作。



只关闭 Form2 ，但我需要两者 Form1 & Form2 消失。我试图寻求一些帮助，但我们无法修复它。

谢谢！

I have tried Close() and Dispose() and using <identifier>.Visible = false; and none worked.

It only closes Form2, but I need both Form1 & Form2 to disappear. I have tried to ask for some help but we weren't able to fix it.
Thank you!

推荐答案

让代码告诉你如何使其工作：

Let codes tell you how to make this worked:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

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

public partial class Form2 : Form
{
    Form1 f1;

    public Form2(Form1 f)
    {
        this.f1 = f;
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        f1.Hide();
        this.Hide();
        new Form3(f1).Show();
    }
}

public partial class Form3 : Form
{
    Form1 f1;
    public Form3(Form1 f1)
    {
        this.f1 = f1;

        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        f1.Close();
    }
}
