Question

当我单击Form Closing按钮（clasic red X按钮）时，我想在系统托盘中隐藏我的应用程序。我提供了这段代码;

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

所以我的程序stil在系统托盘中运行，我添加了一个ContextMenuStrip，当我右键单击我的鼠标contextmenustrip时出现“关闭”，但当我点击“关闭”我的程序仍在运行时我想退出我的应用程序时我点击“关闭”。这是我的代码：

   private void kapatToolStripMenuItem_Click(object sender, EventArgs e) //Close
    {

        DialogResult ext;
        ext = MessageBox.Show("Çıkmak İstediğinizden Emin misiniz?", "Onay", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
        if (ext == DialogResult.Yes)
        {
            Application.Exit();

        }       
    }

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

Answer 1

调用Application.Exit()实际上会尝试关闭所有表单，并且由于您的FormClosing被硬编码为取消，因此无法完成任务。

当前结构的一个选项是创建AllowClose标志。这可以是Form的属性，也可以是全局静态值。

例如：

//in your form
public bool AllowClose {get;set;}

private void Ana_FormClosing(object sender, FormClosingEventArgs e) 
{
    if(!AllowClose)
    {            
        e.Cancel = true; 
        this.Hide();  
    }        
}

//in your context menu event
private void kapatToolStripMenuItem_Click(object sender, EventArgs e) //Close
{

    DialogResult ext;
    ext = MessageBox.Show("Çıkmak İstediğinizden Emin misiniz?", "Onay", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
    if (ext == DialogResult.Yes)
    {
        this.AllowClose = true;
        Application.Exit();
    }       
}

Answer 2

试试这个，

bool isClosing = false;


 private void Ana_FormClosing(object sender, FormClosingEventArgs e) 
    {            
        if(!isClosing)
        {
           e.Cancel = true; 
           this.Hide();          
        }
    }




private void kapatToolStripMenuItem_Click(object sender, EventArgs e) //Close
    {
        DialogResult ext;
        isClosing = true;

        ext = MessageBox.Show("Çıkmak İstediğinizden Emin misiniz?", "Onay", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
        if (ext == DialogResult.Yes)
        {
            Application.Exit();

        }       
    }

C＃从ContextMenuStrip退出应用程序
