问如何获得SignalR用户连接id侧的集线器类？

var HubContext = GlobalHost.ConnectionManager.GetHubContext<"ChatHub">(); //`ChatHub` can be your Hub Name
ChatHub HubObj= new ChatHub();
var RequiredId= HubObj.InvokeHubMethod();

public string InvokeHubMethod()
{
     return "ConnectionID"  //ConnectionID will the Id as string that you want outside the hub
}
