外接程序如何检测何时加载解决方案? [英] How can an add-in detect when a solution is loaded?

问题描述

我的外接程序如何检测何时加载解决方案?我知道DTE模型中的某处肯定有一些事件，但是我找不到它.我的加载项在Visual Studio加载时加载，但这取决于打开的解决方案.在MS失去对COM的恶意修复之前，我不想使其成为解决方案外接程序，因为解决方案外接程序必须是COM组件.

How can my add-in detect when a solution is loaded? I know there must be some event somewhere in the DTE model, but I can't find it. My add-in loads when Visual Studio loads, but it depends on a solution being open. I don't want to make it a solution add-in until MS loses their sick fixation on COM, as solution add-ins have to be COM components.

推荐答案

以下是使用C#注册事件处理的方法:

Here's how to register for event handling using C#:

_solutionEvents = _applicationObject.Events.SolutionEvents;
_solutionEvents.Opened += new _dispSolutionEvents_OpenedEventHandler(SolutionOpened);
_solutionEvents.AfterClosing += new _dispSolutionEvents_AfterClosingEventHandler(SolutionClosed);

还请注意，当用户通过双击解决方案文件打开Visual Studio时，您将不会获得打开解决方案的事件.您应该检查OnStartupComplete方法中的_applicationObject.Solution是否不为null，以正确处理这种情况.

Also note that when user opens Visual Studio by double clicking on a solution file, you won't get an event for solution opening. You should check whether _applicationObject.Solution is not null in OnStartupComplete method to handle this situation correctly.
