对于使.NET程序随系统开机启动，最常用的可能就是向在注册表中注册开机启动项，或是建立Windows服务，使程序随系统启动而启动。
这里以WinForm程序为例，测试Demo分享，同时附上对于程序托盘的简单操作，仿Foxmail的托盘显示效果，好的产品都是细细打磨出来的呀！
1.WinForm程序添加注册表和移除注册表
(1).创建一个WinForm程序，界面如下(很简单)：
(2).主要实现代码：(注册表开机启动位置：SOFTWAREMicrosoftWindowsCurrentVersionRun)
/// <summary> /// 根据注册名称和路径判断是否已注册 /// </summary> /// <param name="regName">注册名称</param> /// <param name="startUpPath">注册路径</param> private void IsExistsStartRun(string regName, string startUpPath) { string strMessage = "注册已移除！"; RegistryKey loca = Registry.LocalMachine; RegistryKey run = loca.CreateSubKey(@"SOFTWAREMicrosoftWindowsCurrentVersionRun"); object obj = run.GetValue(regName); if (obj != null) { strMessage = "注册已添加！"; ControlBtnEnable(false); } else { ControlBtnEnable(true); } lblInitMsg.Text += strMessage; } /// <summary> /// 根据注册名和注册路径，更新注册表信息 /// </summary> /// <param name="regName">注册名</param> /// <param name="startUpPath">注册路径</param> /// <param name="isAddReg">是否添加</param> private void RegCompStartRun(string regName, string startUpPath, bool isAddReg) { //表示Window注册表中项级节点,读取 Windows 注册表基项HKEY_LOCAL_MACHINE RegistryKey localMachine = Registry.LocalMachine; RegistryKey run = localMachine.CreateSubKey(@"SOFTWAREMicrosoftWindowsCurrentVersionRun"); try { //SetValue:存储值的名称 if (isAddReg) { run.SetValue(regName, startUpPath);//加入注册，参数一为注册节点名称(随意) } else { if (run.GetValue(regName) != null)//存在则移除 { run.DeleteValue(regName, false);//删除该注册节点 } } localMachine.Close(); } catch (Exception ee) { MessageBox.Show(ee.Message.ToString(), "提示", MessageBoxButtons.OK, MessageBoxIcon.Error); } }
重新将改程序注册到注册表中，重启电脑，应该就可以了。博客最后是完整代码实现。
2.程序托盘显示控制
(1).在WinForm程序控件库找到notifyIcon控件，将其加到WinForm程序上面，仿Foxmail的托盘程序控制。
随系统自动启动，最小化为托盘在底部显示；单击托盘图标，显示主体程序，继续单击显示和隐藏；单击主窗体关闭按钮，放到托盘显示，右键退出系统，关闭主体程序。
(2).主要实现代码：
/// <summary> /// 初始化消息图标的右键菜单 /// </summary> private void InitNotifyicon() { List<MenuItem> listMenu = new List<MenuItem>(); listMenu.Add(new MenuItem("显示主窗口", new EventHandler(this.notifyIcon_ShowFrm))); listMenu.Add(new MenuItem("-")); listMenu.Add(new MenuItem("最小化系统", new EventHandler(this.notifyIcon_Minimzed))); listMenu.Add(new MenuItem("-")); listMenu.Add(new MenuItem("退出系统", new EventHandler(this.notifyIcon_ExitShow))); this.notifyIcon1.ContextMenu = new ContextMenu(listMenu.ToArray());//消息托盘菜单 } /// <summary> /// 根据是否显示窗体和是否最小化，控制窗体显示 /// </summary> /// <param name="isFrmShow">是否显示主窗体</param> /// <param name="isMinShow">是否为最小化</param> private void IsShowMainFrm(bool isFrmShow, bool isMinShow) { if (!isMinShow) { this.Visible = isFrmShow;//显示在屏幕 this.ShowInTaskbar = isFrmShow;//显示在任务栏 this.WindowState = FormWindowState.Normal; isShowFrm = !isFrmShow;//相反设置 } else { this.Visible = isMinShow;//主窗体可见 this.ShowInTaskbar = isMinShow;//在任务栏显示 isShowFrm = !isFrmShow;//是否显示主窗体控制 this.WindowState = isFrmShow == true ? FormWindowState.Normal : FormWindowState.Minimized; } this.isShowMin = isMinShow;//显示最小化控制 }
3.结合对注册表的操作实现随着系统启动自动启动程序；默认显示为托盘图标显示在底部以及一些显示隐藏控制，仿Foxmail的完成代码实现：

FormWindowState.Normal : FormWindowState.Minimized; } this.isShowMin = isMinShow;//显示最小化控制 } /// <summary> /// 右键菜单显示主窗体事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void notifyIcon_ShowFrm(object sender, System.EventArgs e) { IsShowMainFrm(true, false); } /// <summary> /// 右键菜单退出系统事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void notifyIcon_ExitShow(object sender, EventArgs e) { notifyIcon1.Visible = false;//图标可不见 notifyIcon1.Dispose(); this.Close();//关闭窗体 this.Dispose();//释放资源 } /// <summary> /// 右键菜单最小化事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void notifyIcon_Minimzed(object sender, EventArgs e) { IsShowMainFrm(false, true); } /// <summary> /// 监视窗体大小改变事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void Form1_SizeChanged(object sender, EventArgs e) { if (this.WindowState == FormWindowState.Minimized) { IsShowMainFrm(false, true); } } /// <summary> /// 窗体正在关闭事件 /// 自动放置到托盘 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void Form1_FormClosing(object sender, FormClosingEventArgs e) { IsShowMainFrm(false, false); e.Cancel = true;//取消关闭操作 } /// <summary> /// 消息点击事件 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> private void notifyIcon1_MouseClick(object sender, MouseEventArgs e) { IsShowMainFrm(isShowFrm, isShowMin);//控制主窗体是否显示 } #endregion } }
4.效果图如下：
