C# 如何在C中同时运行HTTP POST和HTTPListener#

我是个新手，希望有人能帮我。我有两个设备作为客户机-服务器或服务器-客户机对。这取决于谁正在向其他设备执行HTTP POST。当设备充当客户端时，我正在实现HTTP POST代码。我还实现了HTTPListener代码，用于 该设备正在充当服务器

我希望HTTPListener在定期发布时与HTTP POST代码并发运行。我不知道这是怎么回事 HTTPListener侦听传入的帖子。它似乎使程序等待，直到识别出首选URI。然后它出现了 接受其他设备的请求并发布数据

我应该将HTTPListener放在程序执行期间随时触发的事件处理程序中吗？我相信这会 暂停当前程序的执行以执行HTTPListener代码。侦听器代码完成后，程序 应该在最初停止的地方继续。我理解正确吗

下面是我的一些代码的简化说明。我希望它相当清楚。感谢您对HTTP和事件概念的帮助，任何人都可以分享

您可以查看WebRequest.GetRequestStreamAsync之类的内容。但是，你可能想看看HttpClient，让事情变得简单一点。我会研究一下。听起来事件和事件处理程序在这里不适用。谢谢你，彼得。
