在socket编程中发送和接收c＃ [英] send and receive in socket programming c#

问题描述

public void receive_send(object obj) {
           Socket sk = (Socket)obj;
           while (true) {
               Byte[] buffer = new Byte[1024];
               int recv = sk.Receive(buffer);
               foreach (Socket temp in listClient)
                   temp.Send(buffer, buffer.Length, SocketFlags.None);
           }
       }

我看了一个应用程序聊天，上面的代码在服务器上。

我有一些关于发送和接收方法的问题。



首先，接收意味着接收来自的数据绑定的System.Net.Sockets.Socket到接收缓冲区，所以 sk.Receive（缓冲区）表示从 sk 接收数据？

它与 ReceiveFrom 方法有什么区别？



Send有同等问题吗？

temp.Send的意思是将数据发送到temp？



这是所有代码的链接。

请阅读。

I looked at an app chat, above code is on server.
I have some problems about send and receive method.

First, Receive means "receives data from a bound System.Net.Sockets.Socket into a receive buffer", so sk.Receive(buffer) mean receive data from sk ?
have any differences between it and ReceiveFrom method?

Equal problem with Send?
temp.Send means "send data to temp" ?

Here is link to all code.

不，不太对劲。这意味着从sk接收数据，这是在计算机上的某个IP和端口上监听。

No, not quite right. It means "receive data from sk, which is listening at a certain ip and port on your computer".

Nope。这意味着您将数据提供给名为temp的对象，然后该对象将数据发送到您之前指定的某个IP和某个端口。

Nope. It means that you give the data to the object called "temp" and afterwards the object sends the data to a certain IP and a certain port which you have specified before.
