如何从服务访问通过RDP映射的磁盘？

Question

RDP具有将来自远程用户工作站的磁盘导出到RDP服务器的出色能力。据我所知，它不仅仅是一个Windows资源管理器技巧，但各种程序都可以使用快捷方式“X：”，“Y：”，“Z：”等... RDP磁盘复制上的stack overflow entry提到指向RDP用户的计算机的'\ tsclient'别名。现在，很明显，如果有2个或更多用户，他们将拥有自己的，没有冲突的tsclient目的地。

所以，我的问题是：如何从服务获取所有远程用户共享资源（磁盘）的列表并访问它？理想情况下，如果说2个用户已经连接并共享了他们的C：驱动器，我会得到如下列表：

• \ UserJohnDoe \ VolumeXyzC - John's C drive
• \ UserJaneRoe \ VolumeXyzC - Jane的C盘

帮助表示感谢！ UPDATE：

这是一段有效的代码（gist snippet）

我认为您可以使用CreateProcessAsUser实现此目的，但您需要检索用户会话的令牌，您可以通过WTSQueryUserToken执行此操作。
