VSTO插件表单关闭处理程序

我有一个outlook 2013的VSTO插件。我试图注册一个事件与窗体关闭事件的事件处理程序。

这是我的代码从类Form1:

    public delegate void MyEventHandler();
    private event MyEventHandler Closing;
    private void OtherInitialize()
    {
        this.Closing += new MyEventHandler(this.Form1_Closing);
    }

也来自类Form1:

    public Form1()
    {
        InitializeComponent();
        OtherInitialize();
    }
    private void Form1_Closing(object sender, CancelEventArgs e)
    {
        // Not sure what to put here to make the application exit completely
        // Looking for something similar to Pytthon's sys.exit() or
        // Applicaton.Exit() in Forms Applicatons, I tried
        // Applicaton.Exit() it did not work
    }

当我运行这个时，我得到错误和警告:

警告:

Form1.Closing hides inherited member System.Windows.Forms.Form.Closing.  Use the new keyword if hiding was intended

错误:

No overload for Form1_Closing matches delegate System.EventHandler

这些错误/警告是什么意思?我怎样才能正确地注册Form1_Closing事件处理程序，当窗体关闭无论是X按钮或form. close()现在我能够调用form. close()，但它似乎没有触发Form1_Closing事件。

不需要声明关闭事件，因为父类提供了开箱即用的事件。此外，您可以简单地设置事件处理程序，而无需声明委托类(最新的。net版本):

public Form1()
{
    InitializeComponent();
    OtherInitialize();
}
private void OtherInitialize()
{
    Closing += Form1_Closing;
}
private void Form1_Closing(object sender, CancelEventArgs e)
{
    // Not sure what to put here to make the application exit completely
    // Looking for something similar to Pytthon's sys.exit() or
    // Applicaton.Exit() in Forms Applicatons, I tried
    // Applicaton.Exit() it did not work
}
