在VS 2015扩展中，如何在解决方案资源管理器中获取选定的对象？ [英] In a VS 2015 extension, how can I get the selected object in the Solution Explorer?

问题描述

我有兴趣为仅选择一个项目的当前选择获取一个Project或ProjectItem（例如，但不限于这两个）。

I'm interested in getting a Project or ProjectItem (as examples, not limited to those two) for the current selection where only a single item is selected.

大多数人似乎正在使用 IVsMonitorSelection 来获取 IVSHierarchy ，然后使用以下内容来获取所选项目的对象（如果选择了单个项目）：

Most people seem to be using IVsMonitorSelection to get an IVSHierarchy and then use the following to get the object for the selected item (in case of a single item being selected):

var monitorSelection = (IVsMonitorSelection) Package.GetGlobalService(typeof(IVsMonitorSelection));

IntPtr hierarchyPointer, selectionContainerPointer;
uint projectItemId;
IVsMultiItemSelect multiItemSelect;

monitorSelection.GetCurrentSelection(out hierarchyPointer, out projectItemId, out multiItemSelect, out selectionContainerPointer);

var hierarchy = (IVsHierarchy) Marshal.GetObjectForIUnknown(hierarchyPointer);

Marshal.Release(hierarchyPointer);
Marshal.Release(selectionContainerPointer);

object o;

hierarchy.GetProperty((uint) projectItemId, (int) __VSHPROPID.VSHPROPID_ExtObject, out o);

但是， GetProperty 在此处返回E_NOTIMPL。我使用了错误的参数吗？

However, GetProperty returns E_NOTIMPL here. Am I using the wrong parameters? Is there an alternative solution perhaps?

推荐答案

根据谢尔盖（Sergey）的回答，我找到了dte.SelectedItems，甚至更多。强类型，不需要强制转换为包含UIHierarchy
项目的数组。

Based on the answer from Sergey, I found dte.SelectedItems, which is even "more strongly-typed" and does not require casting to an array containing UIHierarchy items.

现在的结果是：

dte.SelectedItems.Item（1）.ProjectItem
