问题描述
我的问题是说的称号。究竟是如何做呢？
my question is stated in the title. How exactly do I do that?
我有一个开放的连接，我想劫持，并通过它发送我的自定义信息。从我的理解是与插座和他们的处理程序进行。
I have an open connection and I want to "hijack" it and send my custom messages through it. From my understanding that is done with sockets and their handlers.
任何语言会做，但C＃.NET为preferred。
Any language would do but C#.NET is preferred.
感谢您
更新：我究竟想实现我想要实现PostgreSQL的客户保持活动的系统。这意味着让所有的连接开放的PostgreSQL数据库，并每5分钟查询数据库中选择的版本（），以保持连接活着。这就是它。它是用于教育目的的居多。
UPDATE: What exactly am I trying to achieve: I want to implement a keep-alive system for postgresql clients. That means get all the connections open to a postgresql database and every 5 minutes querying the database "select version()" to keep the connection alive. That's about it. It's for educational purposes mostly.
不过，我想用任何类型的连接。
But I want to use this for any kind of connection.
有人吗？想法？没有？ ：（
Anyone? Ideas? Nothing? :(
