在C＃中使用Microsoft.Vbe.Interop，我可以通过CommandBarEvents访问ReferencesEvents和VBE.Events。
然而，那些有用的MSDN文档似乎表明，当向VBE添加项目或从VBE中删除项目时，我可以使用VBProjectsEvents来通知我的加载项。这正是我想在这里实现的目标。
我可以在对象浏览器中看到_VBProjectsEvents接口，但没有实现它（与_CommandBarControlsEvents接口相反，CommandBarEventsClass接口由{{1}实现使用ReSharper的转到实现功能。
在任何地方都有_VBProjectsEvents接口的实现吗？如果没有，那么如何通知从VB中删除VBProject？

您需要为这些事件创建接收器。
实现const wchar_t sql[]调度接口 - 这是一个通过调用常规托管.net事件来响应这些事件的实现，有效地“包装”_dispVBProjectsEvents事件：
VBProjects public class VBProjectsEventsSink : _dispVBProjectsEvents
{
public event EventHandler<DispatcherEventArgs<VBProject>> ProjectAdded;
public void ItemAdded(VBProject VBProject)
{
if (VBProject.Protection == vbext_ProjectProtection.vbext_pp_none)
{
OnDispatch(ProjectAdded, VBProject);
}
}
public event EventHandler<DispatcherEventArgs<VBProject>> ProjectRemoved;
public void ItemRemoved(VBProject VBProject)
{
if (VBProject.Protection == vbext_ProjectProtection.vbext_pp_none)
{
OnDispatch(ProjectRemoved, VBProject);
}
}
public event EventHandler<DispatcherRenamedEventArgs<VBProject>> ProjectRenamed;
public void ItemRenamed(VBProject VBProject, string OldName)
{
var handler = ProjectRenamed;
if (handler != null && VBProject.Protection == vbext_ProjectProtection.vbext_pp_none)
{
handler.Invoke(this, new DispatcherRenamedEventArgs<VBProject>(VBProject, OldName));
}
}
public event EventHandler<DispatcherEventArgs<VBProject>> ProjectActivated;
public void ItemActivated(VBProject VBProject)
{
if (VBProject.Protection == vbext_ProjectProtection.vbext_pp_none)
{
OnDispatch(ProjectActivated, VBProject);
}
}
private void OnDispatch(EventHandler<DispatcherEventArgs<VBProject>> dispatched, VBProject project)
{
var handler = dispatched;
if (handler != null)
{
handler.Invoke(this, new DispatcherEventArgs<VBProject>(project));
}
}
}
类只是公开事件涉及的DispatcherEventArgs项的一种便捷方式，可以重复用于其他接收器：
VBProject客户端代码需要注册接收器 - 为此，您需要保留public class DispatcherEventArgs<T> : EventArgs
where T : class
{
private readonly T _item;
public DispatcherEventArgs(T item)
{
_item = item;
}
public T Item { get { return _item; } }
}
字段及其IConnectionPoint Cookie：
int private readonly IConnectionPoint _projectsEventsConnectionPoint;
private readonly int _projectsEventsCookie;
集合实现了VBProjects接口，您需要使用该接口来找到连接点：
IConnectionPointContainer获得var sink = new VBProjectsEventsSink();
var connectionPointContainer = (IConnectionPointContainer)_vbe.VBProjects;
var interfaceId = typeof (_dispVBProjectsEvents).GUID;
connectionPointContainer.FindConnectionPoint(ref interfaceId, out _projectsEventsConnectionPoint);
后，使用IConnectionPoint方法“连接”您的接收器并检索 Cookie ：
Advise然后你可以处理接收器事件，就像处理任何“普通”.net事件一样：
_projectsEventsConnectionPoint.Advise(sink, out _projectsEventsCookie);
如果要断开接收器，请将 cookie 传递给sink.ProjectAdded += sink_ProjectAdded;
sink.ProjectRemoved += sink_ProjectRemoved;
sink.ProjectActivated += sink_ProjectActivated;
sink.ProjectRenamed += sink_ProjectRenamed;
实例的Unadvise方法：
IConnectionPoint“那么简单！”
