C#编写最小化时隐藏为任务栏图标的 Window appllication.
this.SizeChanged += new System.EventHandler(this.Form1_SizeChanged);
//上面一行是主窗体InitializeComponent()方法中需要添加的引用
private void Form1_SizeChanged(object sender, EventArgs e)
{
if(this.WindowState == FormWindowState.Minimized)
{
this.Hide();
this.notifyIcon1.Visible=true;
}
}
private void notifyIcon1_Click(object sender, EventArgs e)
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.notifyIcon1.Visible = false;
}
主窗体中拖入一个ContextMenu控件NicontextMenu,点中控件,在上下文菜单中添加菜单,notifyIcon1的ContextMenu行为中选中NicontextMenu 作为上下文菜单。
this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
this.NicontextMenu = new System.Windows.Forms.ContextMenu();
this.menuItem_Hide = new System.Windows.Forms.MenuItem();
this.menuItem_Show = new System.Windows.Forms.MenuItem();
this.menuItem_Aubot = new System.Windows.Forms.MenuItem();
this.menuItem_Exit = new System.Windows.Forms.MenuItem();
this.notifyIcon1.ContextMenu = this.NicontextMenu;
this.notifyIcon1.Icon = ((System.Drawing.Icon)(resources.GetObject( "NotifyIcon.Icon ")));
this.notifyIcon1.Text = " ";
this.notifyIcon1.Visible = true;
this.notifyIcon1.DoubleClick += new System.EventHandler(this.notifyIcon1_DoubleClick);
this.notifyIcon1.Click += new System.EventHandler(this.notifyIcon1_Click);
this.NicontextMenu.MenuItems.AddRange(
new System.Windows.Forms.MenuItem[]
{
this.menuItem_Hide,
this.menuItem_Show,
this.menuItem_Aubot,
this.menuItem_Exit
}
);
//
// menuItem_Hide
//
this.menuItem_Hide.Index = 0;
this.menuItem_Hide.Text = "隐藏 ";
this.menuItem_Hide.Click += new System.EventHandler(this.menuItem_Hide_Click);
//
// menuItem_Show
//
this.menuItem_Show.Index = 1;
this.menuItem_Show.Text = "显示 ";
this.menuItem_Show.Click += new System.EventHandler(this.menuItem_Show_Click);
//
// menuItem_Aubot
//
this.menuItem_Aubot.Index = 2;
this.menuItem_Aubot.Text = "关于 ";
this.menuItem_Aubot.Click += new System.EventHandler(this.menuItem_Aubot_Click);
//
// menuItem_Exit
//
this.menuItem_Exit.Index = 3;
this.menuItem_Exit.Text = "退出 ";
this.menuItem_Exit.Click += new System.EventHandler(this.menuItem_Exit_Click);

我使用的环境:Visual Studio 2005 Professoinal Edition
注意:Windows窗体生成器生成的代码中不能加注释,即使加了注释也会被自动去掉!
使用NotifyIcon控件,该控件的作用是程序运行时在Windows任务栏右侧的通知区域中(任务栏)显示图标。 使用contextMenuStrip控件,该控件可以关联到其它控件,作用是当右击关联的控件时显示菜单。 在NotifyIcon1的属性列表中的contextMenuStrip的下拉列表中选择你刚才创建的contextMenuStrip1菜单。你的托盘程序就拥有一个菜单了。 接下来的与通常图形界面程序的编写相同,首先在[设计]窗口中设计你的界面,然后双击做好的菜单或按钮进入代码窗口写对应的代码。 接下来是一些托盘程序所应具有的一些特别功能的代码
为托盘程序设置双击托盘图标显示/隐藏窗口
首先是在Windows 窗体设计器生成的代码中为托盘图标增加双击事件,具体做法是在具有托盘图标的Form的designer.cs中找到notifyIcon的部分,加入语句
其作用是重载notifyIcon1的双击事件,为其添加方法notifyIcon1_DoubleClick(注意,这里的notifyIcon1和notifyIcon1_DoubleClick可以由你自己设定,可能与这里不同)。
接着我们来实现notifyIcon1_DoubleClick方法,在Form的Class中写方法:
1private void notifyIcon1_DoubleClick(object sender, EventArgs e)
2{
3this.Show();
4if (this.WindowState == FormWindowState.Minimized)
5this.WindowState = FormWindowState.Normal;
6else if (this.WindowState == FormWindowState.Normal)
7this.WindowState = FormWindowState.Minimized;
8this.Activate(); //激活窗体并为其赋予焦点
9}
10
最小化时隐藏窗体(隐藏任务栏上的项目)
首先同样是修改窗体设计器自动生成的代码,在Form1(假设,可能不同)中增加语句
然后实现Form1_Resize方法:
1private void Form1_Resize(object sender, System.EventArgs e)
2{
3if (this.WindowState == FormWindowState.Minimized)
4{
5this.Hide();
6}
7}
将关闭按钮重载为最小化
1protected override void OnFormClosing(FormClosingEventArgs e)
2{
3if (!CloseTag)
4{
5this.WindowState = FormWindowState.Minimized;
6e.Cancel = true;
7}
8else
9e.Cancel = false;
10base.OnFormClosing(e);
11}
12
这里需要说明的是,我的Form1有一个Bool型私有变量CloseTag,另外我的程序有一个关闭按钮,该按钮才是真正的关闭程序。我的做法是当使用我的关闭按钮时将CloseTag设为True,否则CloseTag为false。这样就做到了完整的关闭重载。
