推荐答案

您是指引用单个值吗?现在看来，您正在尝试从整个节点获取键值.路径应该是这样的:

Do you mean to refer a single value? Now it looks like you''re trying to get a key value from a whole node. Should the path be something like:

#define REGDB_SYS_ENV				"SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Environment\\OS"

或您要使用的任何密钥.

or whatever key you''re trying to use.
