如何通过ID向signalR特定的PersistentConnection发送消息？ （使用asp.net mvc4 web-api）

I use class Echo derived from PersistentConnection, and I want to send a message to certain connection:

我使用从PersistentConnection派生的类Echo，我想向某个连接发送消息：

var client = GlobalHost.ConnectionManager.GetConnectionContext<Echo>();
client.Connection.Broadcast(msg);

But I want to send it to specific connection ID. Do I have to create a group for every connection or start using Hubs, or there is a simpler way to select connection by ID, something like:

但我想将它发送到特定的连接ID。我是否必须为每个连接创建一个组或开始使用集线器，或者有一种更简单的方法来按ID选择连接，例如：

GetConnectionById(id).Send(msg);

?

？

Message can be sent to a specific connection ID, but the syntax is not same as what you specified in the question. Following snippet shows the syntax:

消息可以发送到特定的连接ID，但语法与您在问题中指定的语法不同。以下代码段显示了语法：

return Connection.Send(connectionId, Message);

I think, you are aware that SignalR 1 Alpha is released. It is possible to send message to a specific client by its ID if you use this version. Following snippet shows it:

我想，你知道SignalR 1 Alpha已经发布了。如果您使用此版本，则可以通过其ID向特定客户端发送消息。以下代码段显示：

var connection = GlobalHost.ConnectionManager.GetConnectionContext<Echo>().Connection;
connection.Send(((Connection)connection).Identity, "Message to be sent");

Here, ((Connection)connection).Identity gives connection ID of the requesting client.

这里，（（连接）连接）.Identity给出请求客户端的连接ID。
