我使用“Visual Studio的加载项”向导创建一个新的Addin项目,现在我正在尝试添加一些事件处理程序：
- public void OnConnection(object application,ext_ConnectMode connectMode,object addInInst,ref Array custom)
- {
- _applicationObject = (DTE2)application;
- _addInInstance = (AddIn)addInInst;
- _applicationObject.Events.BuildEvents.OnBuildBegin += BuildEvents_OnBuildBegin;
- _applicationObject.Events.BuildEvents.OnBuildDone += BuildEvents_OnBuildDone;
- _applicationObject.Events.SelectionEvents.OnChange += SelectionEvents_OnChange;
- _applicationObject.Events.DocumentEvents.DocumentOpened += DocumentEvents_DocumentOpened;
- _applicationObject.Events.DocumentEvents.DocumentSaved += DocumentEvents_DocumentSaved;
- }
但无论我做什么,我的处理程序都永远不会执行！
我是盲人吗我必须做任何事情来注册这些处理程序,或者为什么不工作？
解决方法
看来你是垃圾收集者的受害者.见：
http://www.mztools.com/articles/2005/mz2005012.aspx
- private readonly BuildEvents _buildEvents;
- private readonly SelectionEvents _selectionEvents;
- private readonly DocumentEvents _documentEvents;
- private readonly Events _events;
- public void OnConnection(object application,ref Array custom)
- {
- _applicationObject = (DTE2)application;
- _addInInstance = (AddIn)addInInst;
- _events = _applicationObject.Events;
- _buildEvents = _events.BuildEvents;
- _buildEvents.OnBuildBegin += BuildEvents_OnBuildBegin;
- _buildEvents.OnBuildDone += BuildEvents_OnBuildDone;
- _selectionEvents = _events.SelectionEvents;
- _selectionEvents.OnChange += SelectionEvents_OnChange;
- _documentEvents = _events.DocumentEvents;
- _documentEvents.DocumentOpened += DocumentEvents_DocumentOpened;
- _documentEvents.DocumentSaved += DocumentEvents_DocumentSaved;
- }
