问题描述
大家好，最近做一个Windows服务是监听某光驱，一旦光驱有光盘时自动读取内容，并通过共享文件的方式传输到服务器上。于是在网上找到了WNetAddConnection2的WindowsAPI函数，通过此函数建立磁盘映射，例如：将\192.168.0.1Share文件夹映射成本地磁盘的P：在控制台程序中没有发生问题，映射磁盘和断开映射都非常成功。但是将程序整理到C#写的Windows服务时，在调用WNetAddConnection2总是返回1312值（正常是返回0表示创建成功）不明白为什么发生这种情况，请教版里的各位大神，这是为什么？是因为Windows服务的权限问题吗？还是WNetAddConnection2还依赖别的服务？

我用这段，可以映射成功
