Question

我有一个只需要NotifyIcon按预期工作的程序。所以我一直试图让程序启动时隐藏主窗体。

在frmMain_Load中，我尝试了两个

this.Hide();
this.Visible = false;

没有成功。

它们可以在其他方法中工作，例如NotifyIcon_MouseClick方法，但我希望它隐藏在Load中。

我在另一个问题中看到了马蒂亚斯提出的这个问题：

BeginInvoke(new MethodInvoker(delegate
{
    Hide();
}));

这很有效，但是当我启动程序时，我可以看到表单快速闪烁。它总比没有好，但我想知道是否有更好的解决方案。

感谢。

Answer 1

// 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

Answer 2

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 ());
}

调用Run的简单事实确实会使表单可见。尝试在表单的属性中执行以下操作：

将WindowState设为Minimized
将ShowInTaskbar设为false

这应该可以解决问题！

Answer 3

不要在表单上调用Show或ShowDialog，您可以让Application.Run定位一个自定义类，然后实例化一个表单，不显示或创建NotifyIcon实例，并从那里处理所有内容。

Answer 4

您也可以在form_shown事件中输入this.hide = true。我相信该事件仅在加载事件之后触发一次。如果您的表单有很多控件和/或计算机很慢，您可能会看到轻微的闪烁。

Answer 5

如果您的程序不需要运行表单，那么最好的方法是根本没有表单。
在程序代码中设置NotifyIcon，并输入一个循环，直到您想通过设置某个值或调用某些方法退出程序。
在此示例中，将UserExitCalled设置为true（Program.UserExitCalled = true）将导致程序退出。

这是一个简短的例子：

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;
    }
}
