Tcp 我从客户端接收数据，但客户端只能在本地PC上从服务器读取数据。为什么？

我有一个TCPC客户端和服务器，在我的电脑上一切正常，如果我将客户端发送到其他电脑（在同一网络中），客户端连接到服务器并可以发送数据，但客户端不读取数据或服务器不发送，我没有任何错误…这是什么原因

我试着用词 从tcp更改为套接字 完全一样 添加防火墙例外 删除防病毒软件

即使我删除了try-catch，我也没有错误，我从服务器和客户端删除了它们，没有错误…

只是快速查看了一下，所以不确定这是否是问题所在，但当您不在自己的本地系统上测试时，您需要告诉程序特定的IP和要连接的端口。只要您在同一子网上，就不必担心端口转发，但您应该让客户端和服务器知道您要使用的端口和地址
