C# 关闭时最小化到系统托盘

C# Minimize to system tray on close

提问by Rakesh

Hi In my c# application I am trying to minimize application to systems tray, when the form is closed. Here is the code I have tried.

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);
        }

    }

and I am calling the method to form closing event. But the problem is its not minimizing to tray. Its just closing the form.

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。它只是关闭表单。

Write a event in Form Closing event.

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();
 }

And write using Custom menu strip for notification icon for to show.

并使用自定义菜单条编写通知图标以显示。

You should cancel the FormClosingevent and then call your MinimizeToTray()function.

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

This is done through the Cancelproperty of the FormClosingEventArgs.

这是通过完成Cancel的财产FormClosingEventArgs。

Also, consider using a boolsomewhere to allowclosing the Formin some conditions, such as if you're using a File > Exitmenu or something:

另外，考虑使用bool某个地方来允许Form在某些情况下关闭，例如如果您使用File > Exit菜单或其他东西：

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

You need to use the FormClosing-Event.

您需要使用 FormClosing-Event。

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

e.Cancel = true;code will be always cancelling the event even if you shut the computer down, but here is a code that helps you:

e.Cancel = true;即使您关闭计算机，代码也将始终取消该事件，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;
     }
 }

It will allow closing the form programmaticaly.

它将允许以编程方式关闭表单。

To minimize when closing set WindowStateto Minimized

关闭时最小化将WindowState设置为Minimized

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

You can handle FormClosingEvent such as micsoft Form Closing Eventas Following example of C#

您可以按照以下 C# 示例处理FormClosing诸如micsoft 表单关闭事件之类的事件

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...
            }
        }
}
