WebSocket问题:此WebSocket实例已经有一个未完成的"SendAsync"调用 [英] WebSocket Issue: There is already one outstanding 'SendAsync' call for this WebSocket instance
问题描述
我正在使用System.Net.WebSockets.WebSocket.SendAsync(..)方法.
I using System.Net.WebSockets.WebSocket.SendAsync(..) method.
我反复面对这个问题.
我了解从这些帖子中，我们一次最多只能执行一个sendAsync操作:
I understand that from these posts we can do at most one sendAsync operation at a time:

推荐答案
您好，JP.M.P，
Hello JP.M.P,
我建议看看这两个使用System.Net.WebSockets的示例项目.客户端一次仅发出一个发送(非阻塞异步).我的猜测是，这是为什么您收到错误消息的关键. 您可以扩展 这样可以向客户端添加一个队列，该队列将在每次响应后将消息发送到服务器.
I suggest taking a look at these two sample projects that use System.Net.WebSockets. The client is only issuing one send at a time (non-blocking async). My guess is this is the key to why you are getting the error message. You could extend this to add a queue to the client that will fire the messages the the server after each response.
