C#跨表單操作(引用傳遞) 執行個體代碼

效果描述：

有三個表單然後順序分別是

(1)點擊第一個表單中的按鈕彈出第二個表單,隱藏第一個表單

(2)第二個表單到一定時間彈出第三個表單

(3)點擊第三個表單的按鈕關閉第三個和第二個表單,彈出第一個表單

From1

複製代碼 代碼如下:using System;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void 開啟form2隱藏form1_Click(object sender, EventArgs e)
{
Form2 f = new Form2();
f.fatherForm = this;
f.Show();
this.Hide();
}
}
}

Form2

複製代碼 代碼如下:using System;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}

public Form1 fatherForm;

private void 開啟from3_Click(object sender, EventArgs e)
{
Form3 f = new Form3();
f.fatherForm = this;
f.Show();
}
}
}

Form3

複製代碼 代碼如下:using System;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
public partial class Form3 : Form
{
public Form3()
{
InitializeComponent();
}

public Form2 fatherForm;

private void 關閉form3from2顯示from1_Click(object sender, EventArgs e)
{
fatherForm.fatherForm.Show();
fatherForm.Close();
this.Close();
}

}
}
