更新時(shí)間：2025年01月19日 11:51:11 作者：VipSoft

這篇文章主要為大家詳細(xì)介紹了C#如何實(shí)現(xiàn)Winform序在系統(tǒng)托盤顯示圖標(biāo)和開機(jī)自啟動(dòng)功能,文中的示例代碼講解詳細(xì),感興趣的小伙伴可以了解下

實(shí)現(xiàn)步驟

創(chuàng)建 NotifyIcon 控件并設(shè)置屬性；
編寫 NotifyIcon 響應(yīng)控制事件；
在主窗體的Load事件中將 NotifyIcon 添加到系統(tǒng)托盤；
程序退出時(shí)，移除系統(tǒng)托盤的 NotifyIcon；

NotifyIcon 控件，通常用于在系統(tǒng)托盤中顯示圖標(biāo)，通過(guò)使用它就可以我們想要的效果。

屬性	描述
Icon	在系統(tǒng)托盤中顯示的圖標(biāo)
Text	鼠標(biāo)懸停在圖標(biāo)時(shí)顯示的文本
Visible	指定是否可見

常用方法

方法	描述
ShowContextMenu	在系統(tǒng)托盤上下文菜單中顯示指定的菜單

添加控件(拖拽方式)

將NotifyIcon和一個(gè)ContextMenuStrip控件。拖到主窗體中可以修改控件名稱

NotifyIcon 托盤圖標(biāo)

ContextMenuStrip 托盤圖標(biāo)右擊彈出的菜單

設(shè)置控件

點(diǎn)擊 ContextMenuStrip 右上方的三角圖標(biāo) -> 編輯項(xiàng)，彈出項(xiàng)信合編輯器

添加右健菜單信息

添加主窗體事件

在最小化或關(guān)閉主窗體時(shí)，顯示在任務(wù)欄托盤區(qū)域,實(shí)現(xiàn)了單擊關(guān)閉時(shí)，不真正關(guān)閉程序，而是將主界面隱藏HIDE掉，同時(shí)開始顯示托盤菜單。

//  只有Form_Closing事件中 e.Cancel可以用。
//  你的是Form_Closed事件。 Form_Closed事件時(shí)窗口已關(guān)了 ，Cancel沒(méi)用了；
//  Form_Closing是窗口即將關(guān)閉時(shí)詢問(wèn)你是不是真的關(guān)閉才有Cancel事件

private void MainWindow_FormClosing(object sender, FormClosingEventArgs e)
{

    // 注意判斷關(guān)閉事件reason來(lái)源于窗體按鈕，否則用菜單退出時(shí)無(wú)法退出!
    if (e.CloseReason == CloseReason.UserClosing)
    {
        //取消"關(guān)閉窗口"事件
        e.Cancel = true; // 取消關(guān)閉窗體 

        //使關(guān)閉時(shí)窗口向右下角縮小的效果
        this.WindowState = FormWindowState.Minimized;
        this.mainNotifyIcon.Visible = true;
        //this.m_cartoonForm.CartoonClose();
        this.Hide();
        return;
    }
}

實(shí)現(xiàn)雙擊托盤打開主程序

//  添加托盤程序
//  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();
    }
}

//  添加托盤程序右鍵菜單項(xiàng)
//  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("你確定要退出？", "系統(tǒng)提示", MessageBoxButtons.YesNo, MessageBoxIcon.Information, MessageBoxDefaultButton.Button1) == DialogResult.Yes)
    {

        this.mainNotifyIcon.Visible = false;
        this.Close();
        this.Dispose();
        System.Environment.Exit(System.Environment.ExitCode);   

    }
}
