问题描述
我有一个简单的TCP套接字客户端和服务器应用程序.他们使用IP =本地主机和端口= 33367进行通信.
I have a simple TCP socket client and server application. They are communicating using IP = localhost and port = 33367.
我正在使用SocketSniff检查通过本地主机的数据包.嗅探客户端应用程序时，我注意到每次以相同的过程向服务器发送数据包时，本地端口"都在更改，而远程端口始终是33367.
I'm using SocketSniff to examine my packets going through localhost. While sniffing the client app, I noticed that every time I'm sending a packet to the server in the same process, the "local port" is changing, while remote port is always 33367.
那么，客户端应用程序是否有可能通过固定端口发送数据(如果是，则使用C#?)，还是必须每次都为它们分配一个不同的端口?
So, is it possible for the client apps to send their data through a fixed port (if so, how in C#?) or do they have to get assigned a different port each time?
推荐答案
您可以在调用connect之前绑定套接字.
You can bind the socket before calling connect.
