求C# *** 编程视频教程!!!!

何需视频？

1.简单服务器端

/*

using System.Data;

using System.Net.Sockets;

using System.Net;

using System.Threading;

*/

private static int port = %%2;

private static Thread thThreadRead;

private static TcpListener TcpListen;

private static bool bListener = true;

private static Socket stRead;

private static void Listen()

{

try

{

TcpListen = new TcpListener(port);

TcpListen.Start();

stRead = TcpListen.AcceptSocket();

EndPoint tempRemoteEP = stRead.RemoteEndPoint;

IPEndPoint tempRemoteIP = (IPEndPoint)tempRemoteEP;

IPHostEntry host = Dns.GetHostByAddress(tempRemoteIP.Address);

string sHostName = host.HostName;

while (bListener)

{

stRead.Send(Encoding.ASCII.GetBytes("Hello"));

string sTime = DateTime.Now.ToShortTimeString();

Byte[] byRead = new Byte[1024];

int iRead = stRead.ReceiveFrom(byRead, ref tempRemoteEP);

Byte[] byText = new Byte[iRead];

Array.Copy(byRead, 0, byText, 0, iRead);

string line = System.Text.Encoding.Default.GetString(byRead);

}

}

catch (System.Security.SecurityException)

{

//监听失败

}

}

thThreadRead = new Thread(new ThreadStart(Listen));

thThreadRead.Start();

2.简单客户端

/*

using System.Data;

using System.Net.Sockets;

using System.Net;

*/

private static IPEndPoint dateTimeHost;

string hostIPString=%%1;

string hostPortString=%%2;

IPAddress hostIP=IPAddress.Parse(hostIPString);

dateTimeHost=new IPEndPoint(hostIP,Int32.Parse(hostPortString));

Socket conn=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);

conn.Connect(dateTimeHost);

int bytes=0;

Byte[] RecvBytes=new Byte[256];

bytes=conn.Receive(RecvBytes,RecvBytes.Length,0);

string RecvString=Encoding.ASCII.GetString(RecvBytes,0,bytes);

Console.WriteLine(RecvString);

conn.Shutdown(SocketShutdown.Both);

conn.Close();

3.获得本机IP

//using System.Net;

IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;

string %%1=null;

for (int i = 0; i addressList.Length; i++)

{

%%1 += addressList[i].ToString();

}

4.端对端通信

/*

using System.Net;

using System.Net.Sockets;

*/

UdpClient client=new UdpClient(%%2);

IPAddress a=IPAddress.Parse("127001");

IPEndPoint receivePoint=new IPEndPoint(a,%%2);

IPAddress HostIP=null;

byte[] sendData=Encoding.UTF8.GetBytes(%%3);

byte[] recData;

try{

HostIP=IPAddress.Parse(%%1);

}

catch {

recData=client.Receive(ref receivePoint);

%%3=Encoding.UTF8.GetString(recData);

client.Send(sendData,sendData.Length,%%4,%%2);

client.Close();

}

IPEndPoint host=new IPEndPoint(HostIP,%%2);

recData=client.Receive(ref receivePoint);

%%3=Encoding.UTF8.GetString(recData);

client.Close();

5.点对点通信

/*

using System.Data;

using System.Net.Sockets;

using System.Net;

using System.Threading;

*/

Thread th;

TcpListener tpListen1;

bool listenerRun=true;

NetworkStream tcpStream;

StreamWriter reqStreamW;

TcpClient tcpc;

Socket skSocket;

protected void Listen()

{

try{

tpListen1=new TcpListener(Int32.Parse(%%2));

tpListen1.Start();

skSocket=tpListen1.AcceptSocket();

EndPoint tempRemoteEP=skSocket.RemoteEndPoint;

IPEndPoint tempRemoteIP=(IPEndPoint)tempRemoteEP;

IPHostEntry host=Dns.GetHostByAddress(tempRemoteIP.Address);

string HostName=host.HostName;

while(listenerRun)

{

Byte[] stream=new Byte[1024];

string time=DateTime.Now.ToString();

int i=skSocket.ReceiveFrom(stream,ref tempRemoteEP);

string %%5=Encoding.UTF8.GetString(stream);

//指定编码，从缓冲区中解析出内容

//time+" "+HostName+":"

}

}

catch(Security.SecurityException)

{

//防火墙安全错误！

}

try{

string sMsg=%%4;

string MyName=Dns.GetHostName();

reqStreamW=new StreamWriter(tcpStream);

reqStreamW.Write(sMsg);

reqStreamW.Flush();

string time=DateTime.Now.ToString();

//显示传送的数据和时间

//time+" "+MyName+":"

//sMsg

}

catch(Exception)

{

//无法发送信息到目标计算机！

}

protected override void Dispose(bool disposing)

{

try{

listenerRun=false;

th.Abort();

th=null;

tpListen1.Stop();

skSocket.Close();

tcpc.Close();

}

catch{}

if(disposing component!=null)

{

components.Dispose();

}

}

base.Dispose(disposing);

}
