C# 多窗口切换的实现

1、目的

在主窗口中根据不同的按钮选择不同的子窗口显示。

2、实现

(1)、创建Winform窗体程序,放入SplitContainer控件splitContainer1将窗体分成左右2部分;

(2)、在左侧splitContainer1.panel1中放入3个Button控件,button1(窗口1)、button2(窗口2)、button3(窗口3);

(3)、创建子窗体Form1,放置2个Label,Title和Content;

(4)、修改Form1的实现代码

public partial class Form1 : Form

{

public Form1(string title,string content)

{

InitializeComponent();

lbTitle.Text = title;

lbContent.Text = content;

}

}

(5)、在主窗体初始化3个Form1窗体

public partial class MainForm : Form

{

public Form1 f1;

public Form1 f2;

public Form1 f3;

public MainForm()

{

InitializeComponent();

}

private void MainForm_Load(object sender, EventArgs e)

{

string title = "窗口一";

string content = "北国风光,千里冰封。";

f1 = new Form1(title, content);

f1.Dock = System.Windows.Forms.DockStyle.Fill;

f1.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

f1.TopLevel = false;

title = "窗口二";

content = "成吉思汗,只识弯弓射大雕。";

f2 = new Form1(title, content);

f2.Dock = System.Windows.Forms.DockStyle.Fill;

f2.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

f2.TopLevel = false;

title = "窗口三";

content = "俱往矣,数风流人物还看今朝。";

f3 = new Form1(title, content);

f3.Dock = System.Windows.Forms.DockStyle.Fill;

f3.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

f3.TopLevel = false;

}

}

(6)、给3个Button控件添加Click处理函数

private void button1_Click(object sender, EventArgs e)

{

f1.Show();

splitContainer1.Panel2.Controls.Clear();

splitContainer1.Panel2.Controls.Add(f1);

}

private void button2_Click(object sender, EventArgs e)

{

f2.Show();

splitContainer1.Panel2.Controls.Clear();

splitContainer1.Panel2.Controls.Add(f2);

}

private void button3_Click(object sender, EventArgs e)

{

f3.Show();

splitContainer1.Panel2.Controls.Clear();

splitContainer1.Panel2.Controls.Add(f3);

}
