.net - 如何退出 VSTO 加载项

Question

有没有比抛出异常更好的方法来从加载项代码中关闭 Outlook 2010 的 VSTO 加载项？

我不喜欢抛出异常，因为 Outlook 可能认为我的加载项不稳定。

关闭是指停止执行加载项代码并隐藏其 UI 或停用。但我希望它在重新启动 Outlook 后启用

当你在VS2010中创建你的VSTO项目时，你里面应该会自动生成下面的代码ThisAddIn.cs .如果没有，您可能想自己添加它们。

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InternalStartup()
{
     this.Startup += new System.EventHandler(ThisAddIn_Startup);
     this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
}

private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
{
     //execute your code here, e.g. output some values to a text file 
}

您可以将代码放在 ThisAddIn_Shutdown 事件中，并仅在加载项关闭时执行它。

编辑:
这是 MSDN 所说的:

Starting in Outlook 2010, Outlook, by default, does not signal add-ins that it is shutting down. Specifically, Outlook no longer calls the OnBeginShutdown and OnDisconnection methods of the IDTExtensibility2 interface during fast shutdown. Similarly, an Outlook add-in written with Microsoft Visual Studio Tools for Office no longer calls the ThisAddin_Shutdown method when Outlook is shutting down.
