套接字连接与绑定？有什么不同 [英] Socket connect vs. bind? What is the difference

问题描述

我正在制作多播服务器客户端设置，并想知道Socket.Connect和Socket.Bind之间的区别是什么。


它可能是一个愚蠢的问题，但我只是好奇。因为我尝试了一个

测试，我不能将两个套接字绑定到同一个端口/ ip但是我可以

连接一个套接字，并绑定到另一个套接字相同的IP /端口。


谢谢

I am makeing a Multicast server client setup and was wondering what the
difference is between Socket.Connect, and Socket.Bind.

It may be a stupid question, but I was just curious. Because I tried a
test, and I can''t bind two sockets to the same port/ip but I can
connect with one socket, and bind with another to the same ip/port.

Thanks

推荐答案

绑定一个Socket与一个本地IPEndPoint。 Connect将Socket

连接到远程IPEndPoint。

Bind associates a Socket with a local IPEndPoint. Connect connects a Socket
to a remote IPEndPoint.

感谢您的回复，但您对联营公司究竟是什么意思，并且

connect 。我想我要问的是有什么不同，当你想要使用一个而不是另一个时，有什么情况。


At这一点我正在使用套接字创建一个多播套接字服务器

setup，在我看到的例子中，发送的套接字通常连接，

和监听的套接字绑定。

Thanks for the reponse, but what exactly do you mean by associate, and
connect. I guess what I''m asking is what is the difference, and when
would you want to use one over the other, what situations.

At this point I''m using sockets to create a multicast socket server
setup, and in examples I saw, the socket that sends typically connects,
and the socket that listens binds.

这是正确的，因为监听器是服务器。您可以将多个

客户端连接到服务器套接字。它比

稍微复杂一点，但基本上，你想将你的服务器绑定到服务器套接字并且

将它设置为Listen。然后您的客户端将连接到服务器套接字以使
与服务器应用程序进行交互。服务器在尝试连接时要为每个要接受的
客户端调用Accept。每个客户

将拥有自己的IPEndPoint，它由IP地址和端口组成。

That''s correct, because the listener is the server. You can have multiple
clients connect to the server socket. It''s a little more complicated than
that, but basically, you want to bind your server to the server socket and
set it to Listen. Then your clients will Connect to the server socket to
interact with the server application. The server calls Accept for each
client that it wants to accept when they attempt to connect. Each client
will have its own IPEndPoint, which is made up of an IP address and a Port.
