这是一个非常友好的框架通知区域应用程序…将NotificationIcon添加到基本表单并将自动生成的代码更改为下面的代码就足够了:

public partial class Form1 : Form
{
    private bool hidden = false;

    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        this.ShowInTaskbar = false;
        //this.WindowState = FormWindowState.Minimized;
        this.Hide();
        hidden = true;
    }

    private void notifyIcon1_Click(object sender, EventArgs e)
    {
        if (hidden) // this.WindowState == FormWindowState.Minimized)
        {
            // this.WindowState = FormWindowState.Normal;
            this.Show();
            hidden = false;
        }
        else
        {
            // this.WindowState = FormWindowState.Minimized;
            this.Hide();
            hidden = true;
        }
    }
}

            this.Hide();
            hidden = true;
        }
    }
}

notifyIcon1->ContextMenu = gcnew

System::Windows::Forms::ContextMenu();
System::Windows::Forms::MenuItem^ nIItem = gcnew
System::Windows::Forms::MenuItem("Open");

nIItem->Click += gcnew System::EventHandler(this, &your_class::Open_NotifyIcon);

notifyIcon1->ContextMenu->MenuItems->Add(nIItem);

在。net 6中，我必须像这样工作我的类的核心:

private NotifyIcon trayIcon;
private ContextMenuStrip contextMenu1;
private ToolStripMenuItem menuItem1;

public MyCustomApplicationContext()
{
    contextMenu1 = new System.Windows.Forms.ContextMenuStrip();
    menuItem1 = new System.Windows.Forms.ToolStripMenuItem();
    this.menuItem1.Text = "E&xit";
    this.menuItem1.Click += new System.EventHandler(Exit);
    this.contextMenu1.Items.AddRange(
            new System.Windows.Forms.ToolStripMenuItem[] {this.menuItem1 });
    trayIcon = new NotifyIcon(){Icon = Resources.AppIcon, ContextMenuStrip = this.contextMenu1, Visible = true };            

}

简单的添加

this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;

到你的表单对象。 你只会在系统托盘上看到一个图标。

据我所知，您仍然必须使用表单编写应用程序，但在表单上没有控件，并且永远不会将其设置为可见。使用NotifyIcon(可以在这里找到它的MSDN示例)来编写应用程序。
