C# Visual Studio扩展：如何获取；路径“；选择时解决方案文件夹的名称？

上一个问题：

我构建了一个能够正确管理Git模块的扩展，为此，我在解决方案中有一个名为SubModules的文件夹

我设法将上下文菜单添加到解决方案文件和项目文件中，但我想在右键单击我的子模块文件夹（即删除、添加）时禁用一些本机命令

我现在知道如何禁用所需的本机命令，但要做到这一点，我需要获取所选解决方案文件夹的“路径”

我尝试实现IVsSelectionEvents，但运气不佳（在施放之前o不为null）：

使用我的代码（来自另一个问题）（我想找到“路径”，但我可以用上面的“解决方案”进行管理），我尝试转换到SolutionFolder或FileProperties。。。仍然没有运气；即使MSDN告诉我们返回的对象应该是FileProperties类型。使用QuickWatch在

（Marshal.GetObjectForIUnknown（selectionContainerPtr）作为iSelectContainer）上进行探索
，我可以进入查看私有属性
\u节点
，在那里，我可以查看我的SolutionFolder节点，并使用其父属性来确保它是我要阻止命令的文件夹。以下是实际代码：

private static void CommandEvents_BeforeExecute(string Guid, int ID, object CustomIn, object CustomOut, ref bool CancelDefault)
{
    string name = GetCommandName(Guid, ID);

    if (name == "Project.AddNewSolutionFolder")
    {
        CancelDefault = true;
    }
    if (name == "Edit.Delete")
    {
        CancelDefault = true;

        IVsMultiItemSelect multiItemSelect = null;
        IntPtr hierarchyPtr = IntPtr.Zero;
        IntPtr selectionContainerPtr = IntPtr.Zero;
        uint itemid = 0;

        int hr = monitorSelection.GetCurrentSelection(out hierarchyPtr, out itemid, out multiItemSelect, out selectionContainerPtr);
        object[] selected = new object[2];
        (Marshal.GetObjectForIUnknown(selectionContainerPtr) as ISelectionContainer).GetObjects(2, 1, selected);


        var t = selected[0] as VSLangProj.FileProperties; // ==> null
        var t2 = selected[0] as SolutionFolder; // ==> null
        var b = 1;
    }

    if (name == "View.Branch")
    {
        //TODO: Could disable this command if not able to find the branch changing command (that would be cancelled and launch ours)
        menuBranchOpened = true;
    }

    if (menuBranchOpened)
    {
        var a = 1;
    }

}

我受到了启发并尝试了（除了上面的一个似乎真的很接近外，没有一个有效）：





最后，在浏览（更多）回答我上一个问题的另一个人的网站时，我终于找到了它。因此，我将分享一个我制作的方法，以了解在解决方案资源管理器中选择的项目类型
