如何从MDIparent表单中的另一个MDIchild表单打开MDIchid表单

问题描述

你好，
在这里，我有4种形式(Form1，Form2，Form3和Form4)，Form1是MdiContainer(IsMdiContainer = true;)，Form2，Form3和Form4是Mdichild形式.
在Form1 Load事件中，我编写了如下代码:

Hello,
Here i is have 4 forms(Form1, Form2, Form3 and Form4) Form1 is MdiContainer(IsMdiContainer = true;), Form2, Form3 and Form4 are Mdichild forms.
In Form1 Load event i wrote the code as follows:

private void Form1_Load(object sender, EventArgs e)
     {
         Form2 f2 = new Form2();
         f2.MdiParent = this;
         f2.ShowDialog();
     }

在Form2表单中，我有两个按钮，分别称为"btnf3"和"btnf4".
1.如果我单击"btnf3"
我拥有将Form3作为Form1的MDI子窗体打开的功能，并且此Form2也必须关闭. (为结束此操作，我写了this.Hide();)
2.如果我单击"btnf4"，我想以Form1的MDI子窗体形式打开Form4，并且还必须关闭Form2(MDI子窗体).

请告诉我我应该在那些按钮单击事件中写些什么
在此先谢谢您.

In Form2 form i have two buttons called "btnf3"and "btnf4".
1.If i click on "btnf3"
i wnat to open Form3 as a MDI child form of Form1 and also this Form2 has to be closed. (for closing this i wrote this.Hide();)
2.If i click on "btnf4" i want to open Form4 as a MDI Child form of Form1 and also close Form2 (MDI child form) has to be closed.

Please tell me what should i write in those buttons click events
Thanks... in advance.
