C#.Net Socket 网络通讯编程
1
、理解socket
2) 、 TCP/IP 传输层使用协议端口将数据传送给一台主机的特定应用程序,从网络的观点看,协议端口是一个应用程序的进程地址。当传输层模块的网络软件模块要与另一个程序通信时,它将使用协议端口。Socket 是运行在传输层的API ,所以在使用Socket 建立连接发送数据时,要指定一个端口给它。 3)
、
根据通信性质的不同,可以把Socket
分成3
类: 4)
、
使用Socket
接口进行网络通信的过程如图5-1
所示,简要步骤如下: 2
、C#
编程要点
2)
、构造一个新的socket
对象
3)
、Socket
的配置和连接
IPAddress
ServerIP=IPAdress.Parse("192.18.16.186"); //
设定服务器IP
地址
4)
、数据的传送和接收
public static string
data=null; //
定义字符串变量存放接收到的信息 5)
、socket
的关闭
