本文为大家分享了C#程序启动项的设置方法，供大家参考，具体内容如下
托盘图标设置
新建一个NotifyIcon，会在托盘处显示一个图标。
NotifyIcon.Icon可以直接设置一个ico图片，也可以延用原有程序的图标。
notifyIcon.Icon = System.Drawing.Icon.ExtractAssociatedIcon(Application.ExecutablePath);
public partial class MainWindow : Window { private NotifyIcon notifyIcon; public MainWindow() { InitializeComponent(); SetNotifyIcon(); this.Hide(); } #region NotifyIcon private void SetNotifyIcon() { this.notifyIcon = new NotifyIcon(); this.notifyIcon.BalloonTipText = "磁盘清理工具"; this.notifyIcon.ShowBalloonTip(2000); this.notifyIcon.Text = "磁盘清理工具:每20天清理一次"; this.notifyIcon.Icon = System.Drawing.Icon.ExtractAssociatedIcon(Application.ExecutablePath); this.notifyIcon.Visible = true; //打开菜单项 MenuItem open = new MenuItem("打开"); open.Click += new EventHandler(Show); //退出菜单项 MenuItem exit = new MenuItem("退出"); exit.Click += new EventHandler(Close); //关联托盘控件 MenuItem[] childen = new MenuItem[] { open, exit }; notifyIcon.ContextMenu = new ContextMenu(childen); this.notifyIcon.MouseDoubleClick += new MouseEventHandler((o, e) => { if (e.Button == MouseButtons.Left) this.Show(o, e); }); } private void Show(object sender, EventArgs e) { this.Visibility = Visibility.Visible; this.ShowInTaskbar = true; this.Activate(); } private void Hide(object sender, EventArgs e) { this.ShowInTaskbar = false; this.Visibility = Visibility.Hidden; } private void Close(object sender, EventArgs e) { System.Windows.Application.Current.Shutdown(); } #endregion #region 窗口 private void MinimizeButton_OnClick(object sender, RoutedEventArgs e) { WindowState = WindowState.Minimized; } private void CloseButton_OnClick(object sender, RoutedEventArgs e) { this.Hide(); } private void HeaderGrid_OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e) { if (e.ButtonState == MouseButtonState.Pressed) { this.DragMove(); } } #endregion } 禁用多进程启动
//禁止双进程 bool canCreateNew; using (System.Threading.Mutex m = new System.Threading.Mutex(true, System.Windows.Forms.Application.ProductName, out canCreateNew)) { if (!canCreateNew) { this.Shutdown(); } } 删除原有进程
/// <summary> /// 删除原有进程 /// </summary> /// <param name="processName"></param> private void KillProcess(string processName) { //得到所有打开的进程 try { Process currentProcess = Process.GetCurrentProcess(); var processes = Process.GetProcessesByName(processName).Where(process=> process.Id!=currentProcess.Id); foreach (Process thisproc in processes) { //找到程序进程,kill之。 if (!thisproc.CloseMainWindow()) { thisproc.Kill(); } } } catch (Exception ex) { } } 设置开机自启动
private void SetAppAutoRun(bool autoRun) { if (autoRun) //设置开机自启动 { string path = System.Windows.Forms.Application.ExecutablePath; RegistryKey rk = Registry.LocalMachine; RegistryKey rk2 = rk.CreateSubKey(@"Software/Microsoft/Windows/CurrentVersion/Run"); rk2.SetValue("JcShutdown", path); rk2.Close(); rk.Close(); } else //取消开机自启动 { RegistryKey rk = Registry.LocalMachine; RegistryKey rk2 = rk.CreateSubKey(@"Software/Microsoft/Windows/CurrentVersion/Run"); rk2.DeleteValue("JcShutdown", false); rk2.Close(); rk.Close(); } } App.cs中完整代码：
public partial class App : Application { public App() { //禁止双进程 bool canCreateNew; using (System.Threading.Mutex m = new System.Threading.Mutex(true, System.Windows.Forms.Application.ProductName, out canCreateNew)) { if (!canCreateNew) { this.Shutdown(); } } SetAppAutoRun(true); Startup += App_Startup; } private void SetAppAutoRun(bool autoRun) { if (autoRun) //设置开机自启动 { MessageBox.Show("设置开机自启动，需要修改注册表", "提示"); // hovertree.com string path = System.Windows.Forms.Application.ExecutablePath; RegistryKey rk = Registry.LocalMachine; RegistryKey rk2 = rk.CreateSubKey(@"Software/Microsoft/Windows/CurrentVersion/Run"); rk2.SetValue("JcShutdown", path); rk2.Close(); rk.Close(); } else //取消开机自启动 { MessageBox.Show("取消开机自启动，需要修改注册表", "提示"); RegistryKey rk = Registry.LocalMachine; RegistryKey rk2 = rk.CreateSubKey(@"Software/Microsoft/Windows/CurrentVersion/Run"); rk2.DeleteValue("JcShutdown", false); rk2.Close(); rk.Close(); } } private void App_Startup(object sender, StartupEventArgs e) { new AutoCleanCacheHelper(CleanCacheVeiwModel.ViewModel).Start(); } } 以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持VEVB武林网。
