C#与linux c 之间的socket通信

最近在做windows上一个工具时用到了socket通信，在此记录一下通讯的程序；通讯是以linux端作为服务，windows端作为客户端，下面直接贴程序

服务端：

#include<stdio.h>  
#include<stdlib.h>  
#include<string.h>  
#include<errno.h>  
#include<sys/types.h>  
#include<sys/socket.h>  
#include<netinet/in.h>  
#define DEFAULT_PORT 8000  
#define MAXLINE 4096  

int main(int argc, char** argv)  
{  
    int    socket_fd, connect_fd;  
    struct sockaddr_in     servaddr;  
    char    buff[4096];  
    int     n;  
    //初始化Socket  
    if( (socket_fd = socket(AF_INET, SOCK_STREAM, 0)) == -1 ){  
        printf("create socket error: %s(errno: %d)\n",strerror(errno),errno);  
        exit(0);  
    }  
    //初始化  
    memset(&servaddr, 0, sizeof(servaddr));  
    servaddr.sin_family = AF_INET;  
    servaddr.sin_addr.s_addr = htonl(INADDR_ANY);//IP地址设置成INADDR_ANY,让系统自动获取本机的IP地址。  
    servaddr.sin_port = htons(DEFAULT_PORT);//设置的端口为DEFAULT_PORT  
  
    //将本地地址绑定到所创建的套接字上  
    if( bind(socket_fd, (struct sockaddr*)&servaddr, sizeof(servaddr)) == -1){  
    printf("bind socket error: %s(errno: %d)\n",strerror(errno),errno);  
    exit(0);  
    }  
    //开始监听是否有客户端连接  
    if( listen(socket_fd, 10) == -1){  
    printf("listen socket error: %s(errno: %d)\n",strerror(errno),errno);  
    exit(0);  
    }  
    printf("======waiting for client's request======\n");  
    while(1){  
        //阻塞直到有客户端连接，不然多浪费CPU资源。  
        if( (connect_fd = accept(socket_fd, (struct sockaddr*)NULL, NULL)) == -1){  
            printf("accept socket error: %s(errno: %d)",strerror(errno),errno);  
            continue;  
        }  
        //接受客户端传过来的数据  
        n = recv(connect_fd, buff, MAXLINE, 0);  
        //向客户端发送回应数据  
        if(!fork()){ 
            if(send(connect_fd, "Hello,you are connected!\n", 26,0) == -1)  
            perror("send error");  
            close(connect_fd);  
            exit(0);  
        }  
        buff[n] = '\0';  
        printf("recv msg from client: %s\n", buff);  
        close(connect_fd);  
    }  
    close(socket_fd);  
} 

客户端：

 1 TcpClient client = new TcpClient();
 2 IPAddress address = IPAddress.Parse(textBox2.Text);
 3 int nPort = 8000;
 4 try
 5 {
 6     client.Connect(address, nPort);
 7 }
 8 catch (SocketException E)
 9 {
10     Console.WriteLine(E.Message);
11     client.Close();
12     Console.ReadLine();
13     return;
14 }
15 NetworkStream sockStream = client.GetStream();
16 string sendMsg = "hello, srver! This is client A";
17 Byte[] sendBuf = Encoding.ASCII.GetBytes(sendMsg);
18 
19 try
20 {
21     sockStream.Write(sendBuf, 0, sendBuf.Length);
22 }
23 catch (SocketException E)
24 {
25     Console.WriteLine(E.Message);
26     sockStream.Close();
27     client.Close();
28     Console.ReadLine();
29     return;
30 }
31 MessageBox.Show("成功向服务器发送消息");
32 sockStream.Close();
33 client.Close();
34 Console.ReadLine();
