实现步骤
- 创建 NotifyIcon 控件并设置属性；
- 编写 NotifyIcon 响应控制事件；
- 在主窗体的Load事件中将 NotifyIcon 添加到系统托盘；
- 程序退出时，移除系统托盘的 NotifyIcon；
NotifyIcon 控件，通常用于在系统托盘中显示图标，通过使用它就可以我们想要的效果。
| 属性 | 描述 |
|---|---|
| Icon | 在系统托盘中显示的图标 |
| Text | 鼠标悬停在图标时显示的文本 |
| Visible | 指定是否可见 |
常用方法
| 方法 | 描述 |
|---|---|
| ShowContextMenu | 在系统托盘上下文菜单中显示指定的菜单 |
添加控件(拖拽方式)
将NotifyIcon和一个ContextMenuStrip控件。拖到主窗体中可以修改控件名称
- NotifyIcon 托盘图标
- ContextMenuStrip 托盘图标右击弹出的菜单
设置控件
点击 ContextMenuStrip 右上方的三角图标 -> 编辑项，弹出项信合编辑器
添加右健菜单信息
添加主窗体事件
在最小化或关闭主窗体时，显示在任务栏托盘区域,实现了单击关闭时，不真正关闭程序，而是将主界面隐藏HIDE掉，同时开始显示托盘菜单。
// 只有Form_Closing事件中 e.Cancel可以用。
// 你的是Form_Closed事件。 Form_Closed事件时窗口已关了 ，Cancel没用了；
// Form_Closing是窗口即将关闭时询问你是不是真的关闭才有Cancel事件
private void MainWindow_FormClosing(object sender, FormClosingEventArgs e)
{
// 注意判断关闭事件reason来源于窗体按钮，否则用菜单退出时无法退出!
if (e.CloseReason == CloseReason.UserClosing)
{
//取消"关闭窗口"事件
e.Cancel = true; // 取消关闭窗体
//使关闭时窗口向右下角缩小的效果
this.WindowState = FormWindowState.Minimized;
this.mainNotifyIcon.Visible = true;
//this.m_cartoonForm.CartoonClose();
this.Hide();
return;
}
}
实现双击托盘打开主程序
// 添加托盘程序
// 版本更新自1.0.1
private void mainNotifyIcon_MouseDoubleClick(object sender, MouseEventArgs e)
{
if (this.Visible)
{
this.WindowState = FormWindowState.Minimized;
this.mainNotifyIcon.Visible = true;
this.Hide();
}
else
{
this.Visible = true;
this.WindowState = FormWindowState.Normal;
this.Activate();
}
}
// 添加托盘程序右键菜单项
// 版本更新自1.0.1
// 退出
// 添加日期 -- 2015-07-29 21:44
private async void toolStripMenuItemQuit_Click(object sender, EventArgs e)
{
if (MessageBox.Show("你确定要退出？", "系统提示", MessageBoxButtons.YesNo, MessageBoxIcon.Information, MessageBoxDefaultButton.Button1) == DialogResult.Yes)
{
this.mainNotifyIcon.Visible = false;
this.Close();
this.Dispose();
System.Environment.Exit(System.Environment.ExitCode);
}
}
