我已经搜索了一天中的大部分时间来试图解决这个问题，而且我确定我在某个地方缺少一个简单的解决方案。
我正在使用异步套接字客户端连接来监视来自 TCP 连接的传入数据。我已经按照 msdn 示例的建议实现了 ManualResetEvent 和 Callback 方法，但是 Callback 方法无法调用用于将接收到的数据输出到我的 Windows 窗体的方法。如何获取从套接字接收到的数据，并将其发送到表单中的文本框？
我敢肯定，我在某处遗漏了一个简单的技巧。示例代码是为控制台应用程序编写的。如何让表单对来自 Socket 的传入数据做出反应？
更新：
我想你让我走上了正确的道路。我尝试输入代码来使用委托，但我显然不太了解委托是如何工作的，因为它不断抛出以下错误：
非静态字段、方法或属性“APRS_SMS_Gateway.MainForm.SockOutputDelegate”需要对象引用
你能让我靠近一点吗？这是我现在正在尝试处理的 ConnectCallBack 处理程序，但我想从所有 CallBacks 中使用相同的方法（SockOutput）。
