启动时将程序放入系统托盘

在主程序中,您可能有一行表单:

Application.Run(new Form1());

这将强制显示窗体。您需要创建表单,但是 不 把它传递给 Application.Run :

Form1 form = new Form1();
Application.Run();

请注意,直到您调用 Application.ExitThread() . 最好是由 FormClosed 事件。

private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
    Application.ExitThread();
}

你就是这样做的

static class Program
{
    [STAThread]
    static void Main()
    {
        NotifyIcon icon = new NotifyIcon();
        icon.Icon = System.Drawing.SystemIcons.Application;
        icon.Click += delegate { MessageBox.Show("Bye!"); icon.Visible = false; Application.Exit(); };
        icon.Visible = true;
        Application.Run();
    }
}

如果您使用 NotifyIcon ,尝试将showintaskbar更改为false。

要将其从alt+tab屏幕中删除,请尝试更改窗口边框样式;我相信某些工具窗口样式不会显示…

类似:

using System;
using System.Windows.Forms;
class MyForm : Form
{
    NotifyIcon sysTray;

    MyForm()
    {
        sysTray = new NotifyIcon();
        sysTray.Icon = System.Drawing.SystemIcons.Asterisk;
        sysTray.Visible = true;
        sysTray.Text = "Hi there";
        sysTray.MouseClick += delegate { MessageBox.Show("Boo!"); };

        ShowInTaskbar = false;
        FormBorderStyle = FormBorderStyle.SizableToolWindow;
        Opacity = 0;
        WindowState = FormWindowState.Minimized;
    }

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.Run(new MyForm());
    }
}

如果它仍然出现在alt+选项卡中,则可以通过p/invoke更改窗口样式(稍微有点hackier):

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    IntPtr handle = this.Handle;
    int currentStyle = GetWindowLong(handle, GWL_EXSTYLE);
    SetWindowLong(handle, GWL_EXSTYLE, currentStyle | WS_EX_TOOLWINDOW);
}
private const int GWL_EXSTYLE = -20, WS_EX_TOOLWINDOW = 0x00000080;
[System.Runtime.InteropServices.DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr window, int index, int value);
[System.Runtime.InteropServices.DllImport("user32.dll")]
private static extern int GetWindowLong(IntPtr window, int index);

作为一个小小的尝试,你可以将启动应用程序的快捷方式配置为“最小化运行”?这可能会给你所需要的!

就像这样:(图片只是谷歌的一个例子)

因为这是用vb.net标记的,下面是我在一个Windows服务和控制器应用程序中所做的,我刚刚完成了,在项目中添加了一个代码模块,在sub main()中设置了notifyIcon及其关联的上下文菜单,然后将应用程序的启动对象设置为sub main()而不是表单。

Public mobNotifyIcon As NotifyIcon
Public WithEvents mobContextMenu As ContextMenu

Public Sub Main()

    mobContextMenu = New ContextMenu
    SetupMenu()
    mobNotifyIcon = New NotifyIcon()
    With mobNotifyIcon
        .Icon = My.Resources.NotifyIcon
        .ContextMenu = mobContextMenu
        .BalloonTipText = String.Concat("Monitor the EDS Transfer Service", vbCrLf, "Right click icon for menu")
        .BalloonTipIcon = ToolTipIcon.Info
        .BalloonTipTitle = "EDS Transfer Monitor"
        .Text = "EDS Transfer Service Monitor"
        AddHandler .MouseClick, AddressOf showBalloon
        .Visible = True
    End With
    Application.Run()
End Sub

Private Sub SetupMenu()
    With mobContextMenu

        .MenuItems.Add(New MenuItem("Configure", New EventHandler(AddressOf Config)))
        .MenuItems.Add("-")
        .MenuItems.Add(New MenuItem("Start", New EventHandler(AddressOf StartService)))
        .MenuItems.Add(New MenuItem("Stop", New EventHandler(AddressOf StopService)))
        .MenuItems.Add("-")
        .MenuItems.Add(New MenuItem("Exit", New EventHandler(AddressOf ExitController)))
    End With
    GetServiceStatus()
End Sub

在config()中,我创建表单的一个实例并显示它。

Private Sub Config(ByVal sender As Object, ByVal e As EventArgs)
    Using cs As New ConfigureService
        cs.Show()
    End Using

End Sub

干得好:

创建2个类,1个从ApplicationContext继承。另一个只包含一个主例程。我做了一个例子,其中有一个表单和一个通知图标,当双击时,会再次显示表单。

记住在“我的项目设置”中将“Sub-Main”设置为启动对象,并指向一个真正的*.ico文件,而不是f:\tp.ico.。:)

当然,代码中应该填充适当的错误处理代码。

第一类:

Imports System.threading 
Imports System.Runtime.InteropServices 
Imports System.Windows.Forms


Public Class Class1

    <System.STAThread()> _
        Public Shared Sub Main()

        Try
            System.Windows.Forms.Application.EnableVisualStyles()
            System.Windows.Forms.Application.DoEvents()
            System.Windows.Forms.Application.Run(New Class2)
        Catch invEx As Exception

            Application.Exit()

        End Try


    End Sub 'Main End Class 

第二类:

Imports System.Windows.Forms  
Imports System.drawing

Public Class Class2
    Inherits System.Windows.Forms.ApplicationContext

    Private WithEvents f As New System.Windows.Forms.Form
    Private WithEvents nf As New System.Windows.Forms.NotifyIcon

    Public Sub New()

        f.Size = New Drawing.Size(50, 50)
        f.StartPosition = FormStartPosition.CenterScreen
        f.WindowState = Windows.Forms.FormWindowState.Minimized
        f.ShowInTaskbar = False
        nf.Visible = True
        nf.Icon = New Icon("f:\TP.ico")
    End Sub


    Private Sub nf_DoubleClick(ByVal sender As Object, ByVal e As EventArgs) Handles nf.DoubleClick
        If f.WindowState <> Windows.Forms.FormWindowState.Minimized Then
            f.WindowState = Windows.Forms.FormWindowState.Minimized
            f.Hide()
        Else
            f.WindowState = Windows.Forms.FormWindowState.Normal
            f.Show()
        End If
    End Sub

    Private Sub f_FormClosed(ByVal sender As Object, ByVal e As FormClosedEventArgs) Handles f.FormClosed
        Application.Exit()
    End Sub  End Class

这将向您展示如何使用notifyicon将启动控制为最小化或正常以及更多。
