C#跨窗体操作，引用传递

现在给大家介绍一种最简单的跨窗体操作

WinForm的窗体是一个类，C#的类是引用类型，那么我们应该可以将WinForm窗体类进行传递，那不就可以进行操作了么？

From1

[csharp]view plaincopy

1. using System;
2. using System.Windows.Forms;
3. namespace WindowsFormsApplication1
4. {
5. public partial class Form1 : Form
6. {
7. public Form1()
8. {
9. InitializeComponent();
10. }
11. private void 打开form2隐藏form1_Click(object sender, EventArgs e)
12. {
13. Form2 f = new Form2();
14. f.fatherForm = this;
15. f.Show();
16. this.Hide();
17. }
18. }
19. }

Form2

[csharp]view plaincopy

1. using System;
2. using System.Windows.Forms;
3. namespace WindowsFormsApplication1
4. {
5. public partial class Form2 : Form
6. {
7. public Form2()
8. {
9. InitializeComponent();
10. }
11. public Form1 fatherForm;
12. private void 打开from3_Click(object sender, EventArgs e)
13. {
14. Form3 f = new Form3();
15. f.fatherForm = this;
16. f.Show();
17. }
18. }
19. }

Form3

[csharp]view plaincopy

1. using System;
2. using System.Windows.Forms;
3. namespace WindowsFormsApplication1
4. {
5. public partial class Form3 : Form
6. {
7. public Form3()
8. {
9. InitializeComponent();
10. }
11. public Form2 fatherForm;
12. private void 关闭form3from2显示from1_Click(object sender, EventArgs e)
13. {
14. fatherForm.fatherForm.Show();
15. fatherForm.Close();
16. this.Close();
17. }
18. }
19. }
