所请求的地址在其上下文中无效UDP数据包捕获程序

Question

我正在尝试通过C＃捕获调制解调器的UDP数据。但是，当我运行代码时，会发生以下异常：

请求的地址在其上下文中无效 system.net.sockets.socket.setmulticastoption（socketOptionName 选件名，多拟合MR）at system.net.sockets.socket.socket.setsocketoption（socketOptionlevel OptionLevel，socketOptionName optionName，Object OptionValue）at C：\ Users \ Muhammed中的caa..ctor（） kara \ source \ repos \ udppragram \ udpprogram \ caa.cs：第25行此处是 Wireshark属性：来源IP：192.168.1.150 DEST IP：192.168.1.140 来源端口：32768 dest端口：50000
