单击x并通过系统托盘ToolStripMenuItem删除时如何隐藏窗口表单

Question

我是C＃.Net的新手，我正在寻找一种方法，当单击窗口中的“ X”（右上角的“关闭”按钮）时隐藏表单窗口，并在我从系统任务栏上下文中单击退出时关闭应用程序菜单

为了简化我想做的事情，我想要像Skype这样的东西，当单击窗口的十字时，它可以通过系统托盘选项退出并隐藏到系统尝试下面是我的代码，我尝试在窗体关闭事件中将cancel属性覆盖为true但是它也停止了系统try选项的关闭过程，如何区分它们。

using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private Icon ico;




        private void Form1_Load(object sender, EventArgs e)
        {
              ico = notifyIcon1.Icon;
        }

        private void contextMenuStrip1_Opening(object sender, CancelEventArgs e)
        {

        }

        private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
        {
            this.Show();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            this.Hide();
        }

        private void showFormToolStripMenuItem_Click(object sender, EventArgs e)
        {
            this.Show();
        }

        private void quitFormToolStripMenuItem_Click(object sender, EventArgs e)
        {

            this.Close();
        }

        private void Form1_FormClosing_1(object sender, FormClosingEventArgs e)
        {
            e.Cancel = true;
                System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
                messageBoxCS.AppendFormat("{0} = {1}", "CloseReason", e.CloseReason);
                messageBoxCS.AppendLine();
                messageBoxCS.AppendFormat("{0} = {1}", "Cancel", e.Cancel);
                messageBoxCS.AppendLine();
                MessageBox.Show(messageBoxCS.ToString(), "FormClosing Event");

        }
    }
}

通常，当我必须这样做时，我会保留一个statusflag来记住该呼叫是从其他地方来关闭我的。 因此，在我的关闭处理程序中，我可以检查是否需要关闭或隐藏...

bool bFormCloseRequested = false: //member of my Form

void MyCloseClick_Handler{object sender, eventArgs e)
{
    if(!bFormCloseRequested)
    {
        e.Cancel = true;
        this.hide();
    }
}
