你的问题太笼统了。你有什么特别的麻烦？您收到了什么错误消息？你用的是什么代码？如果你只是告诉我们一些事情被打破了，我们就无法帮助你。我们不会看到你所看到的。

您根本不想使用RDS。它已经被推荐了很长一段时间，并且从Windows 8和Server 2012开始逐渐消失。



来自MSDN：

从Windows 8和Windows Server 2012开始，Windows操作系统中不再包含RDS服务器组件（有关详细信息，请参阅Windows 8和Windows Server 2012兼容手册）。将来的Windows版本中将删除RDS客户端组件。避免在新的开发工作中使用此功能，并计划修改当前使用此功能的应用程序。使用RDS的应用程序应迁移到 WCF数据服务 [ ^ ]。



你应该通过Web服务，WebAPI或类似方式公开您的数据，然后您的应用程序代码可以连接到它并在代码之外操作数据。

You do NOT want to use RDS at all. It''s been deprecated for quite a while now and is disappearing from Windows starting with Windows 8 and Server 2012.

From MSDN:
Beginning with Windows 8 and Windows Server 2012, RDS server components are no longer included in the Windows operating system (see Windows 8 and Windows Server 2012 Compatibility Cookbook for more detail). RDS client components will be removed in a future version of Windows. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Applications that use RDS should migrate to WCF Data Service[^].

You should be exposing your data through a web service, WebAPI, or similar then your application code can connect to that and have the data manipulated outside of your code.
