C# Vsix（Visual Studio扩展名）右键单击文件的完整路径

我想检索右键单击文件的完整路径（在Visual Studio 2017的编辑器中）。我已经实现了以下代码，用于在打开项目和/或解决方案时检索文件的路径

如果打开单个文件，此实现将不起作用

场景：

开放VS（2017年）

导航到文件->打开->文件

在文件上单击鼠标右键，然后单击所需的关联菜单。（它调用IsSingleProjectItemSelection方法）

monitorSelection.GetCurrentSelection（out hierarchyPtr

失败，因为

hierarchyPtr

保持IntPtr.Zero

值不能为null。参数名称：pUnk

也许您知道在Visual Studio编辑器（2017）中检索右键单击文件的完整路径的解决方案

先谢谢你

    if (!IsSingleProjectItemSelection(out hierarchy, out itemid)) return;
        // Get the file path
        string itemFullPath = null;
        ((IVsProject) hierarchy).GetMkDocument(itemid, out itemFullPath);
        var transformFileInfo = new FileInfo(itemFullPath);    
        string fullPath = itemFullPath.FullName;

public static bool IsSingleProjectItemSelection(out IVsHierarchy   hierarchy, out uint itemid)
{
    hierarchy = null;
    itemid = VSConstants.VSITEMID_NIL;
    int hr = VSConstants.S_OK;

    var monitorSelection = Package.GetGlobalService(typeof(SVsShellMonitorSelection)) as IVsMonitorSelection;
    var solution = Package.GetGlobalService(typeof(SVsSolution)) as IVsSolution;
    if (monitorSelection == null || solution == null)
    {
        return false;
    }

    IVsMultiItemSelect multiItemSelect = null;
    IntPtr hierarchyPtr = IntPtr.Zero;
    IntPtr selectionContainerPtr = IntPtr.Zero;

    try
    {
        hr = monitorSelection.GetCurrentSelection(out hierarchyPtr, out itemid, out multiItemSelect, out selectionContainerPtr);

        if (ErrorHandler.Failed(hr) || hierarchyPtr == IntPtr.Zero || itemid == VSConstants.VSITEMID_NIL)
        {
            // there is no selection
            return false;
        }

        // multiple items are selected
        if (multiItemSelect != null) return false;

        // there is a hierarchy root node selected, thus it is not a single item inside a project

        if (itemid == VSConstants.VSITEMID_ROOT) return false;

        hierarchy = Marshal.GetObjectForIUnknown(hierarchyPtr) as IVsHierarchy;
        if (hierarchy == null) return false;

        Guid guidProjectID = Guid.Empty;

        if (ErrorHandler.Failed(solution.GetGuidOfProject(hierarchy, out guidProjectID)))
        {
            return false; // hierarchy is not a project inside the Solution if it does not have a ProjectID Guid
        }

        // if we got this far then there is a single project item selected
        return true;
    }
    finally
    {
        if (selectionContainerPtr != IntPtr.Zero)
        {
            Marshal.Release(selectionContainerPtr);
        }

        if (hierarchyPtr != IntPtr.Zero)
        {
            Marshal.Release(hierarchyPtr);
        }
    }
}
