我不能工作，为什么不会触发事件。

 私人列表＆LT; _Outlook.Explorer＆GT; ListOfExplorerWindows =新的List＆LT; _Outlook.Explorer＆GT; {};
私人_Outlook.Application应用;公共无效的OnConnection（对象应用程序，Extensibility.ext_ConnectMode ConnectMode，对象AddInInst，楼盘阵列定制）

    Explorer.FolderSwitch + =新_Outlook.ExplorerEvents_10_FolderSwitchEventHandler（Explorer_FolderSwitch）;
    ListOfExplorerWindows.Add（资源管理器）;
}
 

解决方案

有关你想使用VSTO时保持周围的任何事件，您需要保持周围的类级成员（ 资源管理器，应用，检查，命令栏等的），以保持GC线程从删除它们。这是一个资源优化，也可以是一个惨痛的教训中学习。

请参阅相关的<一个href=\"http://social.msdn.microsoft.com/Forums/en-US/vsto/thread/2debdd37-daf0-4966-8e12-f5eec01849e0\">MSDN论坛发帖对事件一生或相似，所以帖子。

For some reason in my app my FolderSwitch works on the main Explorer that opens with the application but the NewExplorer event never fires, so obviously the FolderSwitch event won't fire on a new Explorer.

I can't work out why the event doesn't fire.

private List<_Outlook.Explorer> ListOfExplorerWindows = new List<_Outlook.Explorer> { };
private _Outlook.Application Application;

public void OnConnection(object Application, Extensibility.ext_ConnectMode ConnectMode, object AddInInst, ref Array custom)
{
    this.Application = (_Outlook.Application)Application;
}

public void OnStartupComplete(ref Array custom)
{
    _Outlook.Explorer Explorer = this.Application.ActiveExplorer();
    Explorer.FolderSwitch += new _Outlook.ExplorerEvents_10_FolderSwitchEventHandler(Explorer_FolderSwitch);
    ListOfExplorerWindows.Add(Explorer);

    this.Application.Explorers.NewExplorer += new _Outlook.ExplorersEvents_NewExplorerEventHandler(Explorers_NewExplorer);
}

private void Explorers_NewExplorer(_Outlook.Explorer Explorer)
{
    Explorer.FolderSwitch += new _Outlook.ExplorerEvents_10_FolderSwitchEventHandler(Explorer_FolderSwitch);
    ListOfExplorerWindows.Add(Explorer);
}

解决方案

For any events you want to keep around when using VSTO, you are required to keep around a class-level member (Explorer, Application, Inspector, CommandBar, etc.) to keep the GC Thread from removing them. This is a resource optimization, but can also be a painful lesson to learn.
