推荐答案

向特定用户发送消息的唯一方法是通过用户的连接ID寻址该用户.在这种情况下，他是否属于特定组并不重要.除此之外，没有可以迭代的内置列表，您需要自己管理这些引用.

The only way to send a message to a specific user is by addressing the user by its connection Id. In this case it doesn't matter if he is in a specific group or not. Other than that there's no such thing as a built-in list, that you can iterate on, you need to manage those references by yourself.

当然，如果所需的用户是发件人，则可以使用 Clients.Caller .

Of course, if the desired user is the sender, you can use Clients.Caller.
