使用套接字客户端发送具有特定端口范围的数据 [英] Using socket client to send data with specific ports range

问题描述

首先，请看下面的源代码：

 IPEndPoint endpoint = new IPEndPoint（IPAddress.Parse（" 192.168.0.2"），90）; 
 
 Socket socketSend = new Socket（AddressFamily.InterNetwork，SocketType.Dgram，ProtocolType.Udp）; 
 
 socketSend.Connect（endpoint）; 
 
 if（socketSend.Connected）
 socketSend.Send（data.ToArray（））; 
 

这些代码用于将数据发送到端口的ip 192.168.0.2:90。来自收到的在ip 192.168.0.2和端口90的一侧，我看到我的ip：192.168.0.3的端口总是被改变（随机）。是否可以使用静态端口设置socketSend，以便当数据通过ip 192.168.0.2和端口90到达时，端口始终是静态的？或者是否可以为socketSend设置一系列可能的端口？ 

提前致谢。

解决方案

您可以使用Socket.Bind（）将本地套接字绑定到特定端口。然后，从该套接字发送的所有数据报都将源端口设置为您指定的数据报。

Hi,

First, please take a look at my source code following:

IPEndPoint endpoint = new IPEndPoint(IPAddress.Parse("192.168.0.2"), 90);

Socket socketSend = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);

socketSend.Connect(endpoint);

if (socketSend.Connected)
       socketSend.Send(data.ToArray());

That pieces of code is used to send data to the ip 192.168.0.2 at the port: 90. From the received side of the ip 192.168.0.2 and port 90, I see that the port from my ip: 192.168.0.3 is always changed (randomly). Is it possible to set the socketSend with a static port so that when the data is arrived ath the ip 192.168.0.2 and the port 90, the port is always static? or is it possible to set a range of possible ports for the socketSend? 

Thanks in advance.

解决方案

You can use Socket.Bind() to bind the local socket to a particular port. Then, all datagrams sent from that socket will have the source port set to the one you specified.
