c# - C# 关闭时最小化到系统托盘

Question

嗨，在我的 c# 应用程序中，当表单关闭时，我试图将应用程序最小化到系统托盘。这是我尝试过的代码。

   public void MinimizeToTray()
    {
        try
        {
            notifyIcon1.BalloonTipTitle = "Sample text";
            notifyIcon1.BalloonTipText = "Form is minimized";

            if (FormWindowState.Minimized == this.WindowState)
            {
                notifyIcon1.Visible = true;
                notifyIcon1.ShowBalloonTip(500);
                this.Hide();
            }
            else if (FormWindowState.Normal == this.WindowState)
            {
                notifyIcon1.Visible = false;
            }
        }
        catch(Exception ex)
        {
            MessageBox.Show(ex.Message);
        }

    }

我正在调用该方法来形成关闭事件。但问题是它没有最小化到托盘。它只是关闭表格。

e.Cancel = true;即使您关闭计算机，代码也将始终取消事件，但这里有一个代码可以帮助您：

 private void Form1_FormClosing(object sender, FormClosingEventArgs e)
 {
     if (e.CloseReason == CloseReason.UserClosing)
     {
          myNotifyIcon.Visible = true;
          this.Hide();
          e.Cancel = true;
     }
 }

它将允许以编程方式关闭表单。

在表单关闭事件中编写一个事件。

 private void Form1_FormClosing(object sender, FormClosingEventArgs e)
 {
        e.Cancel = true;                         
        Hide();
 }

并使用自定义菜单条写入通知图标以显示。

   namespace MinimizeTrayNotification
     {
      public partial class Form1 : Form
       {
    public Form1()
    {
        InitializeComponent();
    }

    private void MinimzedTray()
    {
        notifyIcon1.Visible = true;
        notifyIcon1.Icon = SystemIcons.Application;

        notifyIcon1.BalloonTipText = "Minimized";
        notifyIcon1.BalloonTipTitle = "Your Application is Running in BackGround";
        notifyIcon1.ShowBalloonTip(500);

    }

    private void MaxmizedFromTray()
    {
        notifyIcon1.Visible = true;
        notifyIcon1.BalloonTipText = "Maximized";
        notifyIcon1.BalloonTipTitle = "Application is Running in Foreground";
        notifyIcon1.ShowBalloonTip(500);


    }



    private void Form1_Resize(object sender, EventArgs e)
    {
        if(FormWindowState.Minimized==this.WindowState)
        {
        MinimzedTray();
        }
      else  if (FormWindowState.Normal == this.WindowState)
        {

            MaxmizedFromTray();
        }
        }

    private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        this.WindowState = FormWindowState.Normal;
        Form1 frm = new Form1();
        frm.Show();
        MaxmizedFromTray();


    }

    private void notifyIcon1_MouseClick(object sender, MouseEventArgs e)
    {
        this.WindowState = FormWindowState.Normal;
    }

    private void Form1_FormClosing(object sender, FormClosingEventArgs e)
    {
        if (e.CloseReason == CloseReason.UserClosing)
        {
            e.Cancel = true;
            this.WindowState = FormWindowState.Minimized;
            this.ShowInTaskbar = false;
            this.Hide();

        }


    }

    private void notifyIcon1_Click(object sender, EventArgs e)
    {
        this.WindowState = FormWindowState.Normal;
        notifyIcon1.BalloonTipText = "Normal";
        notifyIcon1.ShowBalloonTip(500);
    }
 }

}

您应该取消该FormClosing事件，然后调用您的MinimizeToTray()函数。

这是通过Cancel.FormClosingEventArgs

另外，考虑在某些情况下使用bool某个地方来允许关闭Form，例如，如果您正在使用File > Exit菜单或其他东西：

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if(!allowClosing)
    {
        e.Cancel = true;
        MinimizeToTray();
    }
}

要在关闭时最小化，请将WindowState设置为Minimized

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
    e.Cancel = true;
    WindowState = FormWindowState.Minimized;
}

您需要使用 FormClosing-Event。

private void Form1_FormClosing(Object sender, FormClosingEventArgs e) {
    e.Cancel = true;
    MinimizeToTray();
}

您可以按照以下 C# 示例处理FormClosing诸如micsoft Form Closing Event之类的事件

private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
    {
        // Determine if text has changed in the textbox by comparing to original text.
        if (textBox1.Text != strMyOriginalText)
        {
            // Display a MsgBox asking the user to save changes or abort.
            if (MessageBox.Show("Do you want to save changes to your text?", "My Application",
                MessageBoxButtons.YesNo) == DialogResult.Yes)
            {
                // Cancel the Closing event from closing the form.
                e.Cancel = true;
                // Call method to save file...
            }
        }
}
