我有一个程序，只需要一个NotifyIcon就能正常运行。因此，我一直在尝试让主窗体在程序启动时隐藏。
在frmMain_Load中，我尝试了以下两种方法：
this.Hide();
this.Visible = false;
没有成功。
它们在其他方法中起作用，比如在NotifyIcon_MouseClick方法中，但我希望在加载时隐藏。
我在SO的另一个问题中看到Matias建议了这个：
BeginInvoke(new MethodInvoker(delegate
{
Hide();
}));
这个方法可以用，但当我启动程序时，我可以看到表单闪烁得非常快。虽然比什么都没有要好，但我想知道是否有更好的解决方案。
谢谢。
// In Your Program.cs Convert This
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
// To This
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Form1 TheForm = new Form1();
Application.Run();
}
// Call Application.Exit() From Anywhere To Stop Application.Run() Message Pump and Exit Application
如果您的程序具有默认的Visual Studio生成的Program.cs文件，则有一种简单的方法：
[STAThread]
static void Main()
{
Application.EnableVisualStyles ();
Application.SetCompatibleTextRenderingDefault (false);
Application.Run (new MainForm ());
}
仅仅调用Run方法就可以让窗体显示出来。在您的窗体属性中尝试以下操作：
WindowState设置为MinimizedShowInTaskbar设置为false这样应该就可以了！
你也可以在form_shown事件中加入this.hide = true。我相信该事件仅会在load事件之后触发一次。但是，如果你的表单有很多控件和/或计算机速度较慢，可能会看到一些闪烁。
如果你的程序不需要表格运行，那么最好的方法就是不要有表格。
在程序代码中设置你的NotifyIcon，然后进入循环，直到你想通过设置某个值或调用某个方法退出程序为止。
例如，将UserExitCalled设置为true（Program.UserExitCalled = true）将导致程序退出。
以下是一个简短的示例：
static class Program {
internal static Boolean UserExitCalled;
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main() {
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
// Setup your tray icon here
while (!UserExitCalled) {
Application.DoEvents(); // Process windows messages
Thread.Sleep(1);
}
return;
}
}

ApplicationContext，并将其实例传递给Application.Run()，它管理窗体的生命周期，从而避免在其他地方调用Application.Exit()的需要。 - Quolonel Questions
