# Ethernet
Ethernet library for C#. This library allows users send UDP messages over Ethernet (TCP/IP).
It also provides interface for using sockets.
## Installation
To install this library use following command:
Install-Package Ethernet -Version 1.1.0
## Usage
### Using sockets
Using socket interface is very simple.
csharp
// Create socket object.
Socket socket = Socket.CreateSocket(SocketType.Datagram);
// Connect socket.
socket.Connect(new IPEndPoint(IPAddress.Parse("192.168.1.10"), 11000));
// Send message.
socket.Send("Hello World");
// Receive message.
byte[] buffer = new byte[1024];
int receivedBytesCount = socket.Receive(buffer);
Console.WriteLine(Encoding.ASCII.GetString(buffer));
### Using Client
You can also use Client class which implements IDisposable interface.
csharp
// Create client object.
var client = new Client(new IPEndPoint(IPAddress.Parse("192.168.1.10"), 11000));
// Send message.
client.Send("Hello World");
// Receive message.
var responseMessage = await client.ReceiveAsync();
Console.WriteLine(responseMessage.Message);
await client.DisposeAsync();
### Using Server
Server class implements IDisposable interface as well.
csharp
// Create server object.
var server = new Server(new IPEndPoint(IPAddress.Any), 11000);
// Wait for connection request from client.
var requestTaskAwaiter = server.ConnectionRequestAsync.Task.GetAwaiter();
if (!requestTaskAwaiter.IsCompleted)
{
await requestTaskAwaiter;
}
var connectionRequestMessage =
await server.ConnectionRequestAsync;
if (connectionRequestMessage == null)
{
Console.WriteLine("No connection request");
return;
}
Console.WriteLine(connectionRequestMessage.Message);
// Create connection object which holds information about connected client.
Connection connection =
await server.CreateConnectionAsync(connectionRequestMessage.SocketHandle);
await connection.SendAsync("Hello World");
var responseMessage =
await connection.ReceiveAsync();
Console.WriteLine(responseMessage.Message);
await server.DisposeAsync();

本文主要是对C#中网络编程的一些总结,涉及到的知识点包括:
* Socket编程基础(UDP和TCP)
* Socket编程进阶(多线程、异步、消息队列、Select)
* Socket编程高级(反射与泛型)
这篇文章的目的是为了帮助初学者入门Socket编程,所以可能会有很多不严谨之处,如果你发现有错误或者不妥之处,请随时联系我。
如果你是一个老司机,已经精通Socket编程,但又想看看别人是怎么写的,那么请继续往下看吧。
# 基础篇:UDP和TCP的基本使用方法
## 网络编程三大核心概念:IP地址、端口号和协议类型
在网络编程中,我们常说到三个概念:IP地址、端口号和协议类型。那么什么是IP地址呢?什么是端口号呢?什么又是协议类型呢?
**IP地址**就像我们住在一个城市里面的家庭住址一样,在互联网上可以通过IP地址找到某台主机。而**端口号**则像一栋楼里面的房间号,用来标识某个应用程序。最后**协议类型**就像楼内电话系统中两个人之间沟通时使用的语言一样,在网络中两台主机之间交换数据时使用什么样的协议。
当我们说“我想给你发一个消息”时,对方肯定需要知道以下三个信息:
* 我要给谁发消息(目标主机)——即IP地址。
* 在对方主机上哪个应用程序能够接收到我的消息——即端口号。
* 我们用什么样的方式交流——即协议类型。
比如说我想给朋友张三发送一个邮件,那么我就需要知道以下信息:
* 张三所在城市(目标主机)——即张三家庭住址。
* 张三家庭住址里面哪套房子可以接收我的邮件——即张三家庭住址里面哪套房子有邮件信箱。
* 我们用什么样的方式交流——即邮递员是否能够把信送到张三家,并且张三是否能够读懂我的信。
当然了,如果我们只是想通过微信或者QQ聊天而不需要发邮件时,则不需要知道以上信息。但无论如何,在网络世界中还是需要这些信息才能完成一次通讯。
## IP地址与端口号如何表示?
首先来看看如何表示一个IP地址和端口号。
一个典型的IPv4格式为“192.168.x.x”,其中x代表0~255之间任意整数。比如说“192.168.xx.xx”可以表示成“192.168.xxx.xxx”,其中x代表任意整数。注意到每个小段范围都是从0~255之间任意整数,也就意味着每个小段都可以表示成3位十进制数字或者1位十六进制数字。因此可以将其转换成16进制格式为“C0.A8.xx.xx”。
同理,“xxx.xxx.xxx.xxx”也可以转换成16进制格式为“xx.xx.xx.xx”。
而对于IPv6格式来说,则可表示成8组16进制数字组合而成。“xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx”则可转换成16进制格式为“xx:xx:xx:xx:xx:xx:x:x”。
由于端口号范围只有从0~65535之间任意整数,则其可表示为两组16进制数字组合而成:“xx.xx”。也就意味着每个小段都可以表示成4位十六进制数字。
下图展示了以上几种格式对应关系:

## 协议类型介绍及其相关概念简介:SOCKET、SOCK_DGRAM和SOCK_STREAM
在C++中常见有两种协议类型:SOCK_DGRAM和SOCK_STREAM。其中SOCK_DGRAM对应UDP协议(User Datagram Protocol),而SOCK_STREAM对应TCP协议(Transmission Control Protocol)。前者提供无连接服务而后者则提供面向连接服务。
C#中没有明确区分这两种协议类型,在.NET Framework下提供了Socket类来实现相同功能。其中Socket类提供了几种常量来描述不同协议类型:
c#
public static readonly int Datagram; // 对应UDP协议。
public static readonly int Stream; // 对应TCP协议。
public static readonly int Raw; // 对应RAW协议。
public static readonly int Rdm; // 对应RDM协议。
public static readonly int Seqpacket; // 对应SEQPACKET协议。
由于本文重点讨论基于UDP和TCP进行网络通讯,则只需要关注Datagram和Stream这两个常量即可。
在Windows平台下还存在另外一个概念叫做SOCKET,它属于Winsock API提供的一种特殊对象,专门用于描述Internet 连接。SOCKET对象通过调用WSASocket函数创建,并且其操作方法与普通文件对象类似。同时Windows平台下支持五种不同类型操作模式:
c#
typedef enum {
SOCK_STREAM , /* stream socket */
SOCK_DGRAM , /* datagram socket */
SOCK_RAW , /* raw protocol access */
SOCK_RDM , /* reliably-delivered message */
SOCK_SEQPACKET /* sequenced packet stream */
} SOCKET_PROTOCOL_TYPE ;
其中第一个元素`SOCK_STREAM`对应于`TcpProtocolType.Tcp`,第二个元素`SOCK_DGRAM`对应于`TcpProtocolType.Udp`.
另外还有几个重要概念值得说明:

### 面向连接与无连接服务区别解析以及其优缺点分析
无连接服务指客户端发送请求后立刻得到服务器返回结果并断开连接;而面向连接服务指客户端发送请求后会先建立连接再获取服务器返回结果并断开连接。
从性能角度来说无连接服务效率更高;从稳定性角度来说面向连接服务更加稳定可靠;从安全性角度来说面向连接服务更加安全可靠;从灵活性角度来说无连接服务更加灵活自由。
### UDP与TCP差异分析及其优缺点分析
首先来看看UDP与TCP差异分析:

然后再来看看它们各自优缺点分析:

根据以上内容总结出以下结论:

## 如何创建基本Socket实例并进行简单数据传输?
首先创建一个新项目作为测试工具代码库:
