使用vb.net的套接字 [英] Sockets usage with vb.net
问题描述
您好！
我有一些设备可以通过局域网与服务器进行通信我使用的旧的
表单是FTP作为服务器和服务器之间的通信客户i
决定使用个人TCP套接字而不是使用FTP
协议。我很熟悉套接字，但有些概念我无法获得它。我会使用Vb.Net作为服务器程序，但问题
呵护我的大脑是为了例如.. ip 192.168.0.0.1尝试在服务器上进行通信
端口5444和同时另一台设备用ip
192.168.0.0.2尝试在端口5444上进行通信什么是
结果在这种情况下设备用ip xxx1仍在使用端口
其他设备可以在同一端口上进行通信。
问候

Hello !
I have some devices which communicate trough LAN to the server the old
form i was using was FTP as a communication between Server and Client i
have decided to use personal TCP sockets instead of using the FTP
protocol. Well im familar with sockets but some concepts im not able to
get it. I would be using Vb.Net as a server program but the question
pampering my brain is for eg .. ip 192.168.0.0.1 tries to communicate
on the server port 5444 and at the same time another device with ip
192.168.0.0.2 tries to communicate on port 5444 what would be the
result in this case the device with ip x.x.x.1 is still using the port
will the other device can communicate on the same port .

推荐答案
你不是说IP：192.168.0.1&不是192.168.0.0.1？
您可以使用其中一个重载函数来传递特定的端口号。
只需查看套接字类获取信息
VB.NET大大简化了套接字编程

Don''t you mean IP: 192.168.0.1 & not 192.168.0.0.1?
You can use one of the overloaded functions to pass a specific port number.
Just see the sockets class for information
Socket programming is greatly simplified with VB.NET

将另一台设备可以在同一个港口沟通。

这是基本概念：
您使用一个端口建立连接（在这种情况下为端口5444）然后您
在随机端口号处打开一个新端口（框架将选择一个端口
for you）这个新端口是所有通信完成的端口，
离开端口5444进行下一次连接。

This is the basic concept:
You use one port to make a connection (port 5444 in this case) then you
open a new port at a random port number (the framework will pick a port
for you) This new port is the one all the communication is done on,
leaving port 5444 for the next connection.

很抱歉，但我认为只有UDP连接需要释放公共端口
（在这种情况下为5444），并创建一个随机端口进行通信。用于TCP和UDP连接的
套接字是否以相同的方式工作？
如果我错了，请指出我。谢谢。

Sorry, but I thought only UDP connections needs to release the public port
(5444 in this case), and create a random port for communication. Is the
socket for TCP and UDP connection works in same way?
Please point me out if I am wrong. Thanks.
