C#实现Winform序在系统托盘显示图标和开机自启动_Asp.net

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);   

    }
}
