1 Socket方式
连接按钮：
服务器: 新建一个socket-->.Bind,绑定IPEndPoint-->.Listen,监听 -->.Accept
客户端：新建一个socket-->.Connect
新建一个线程thread对应receive函数
thread.Start()
//receive函数：接收代码用一个while循环起来。
if
(AcceptSocke连接上)
try
{接收}
catch
{报警;断开;重新监听}
服务器
try
{
//主程序
ChatServer=new IPEndPoint(IPAddress.Parse(textBox4.Text);Int32.Parse(textBox5.Text));
ChatSocket=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
ChatSocket.Bind(ChatServer);//绑定，监听
ChatSocket.Listen(50);
statusBar2.Text=textBox1.Text+" has logoned on.Now begin to listen
";
AcceptedSocket = ChatSocket.Accept();
Thread thread=new Thread(new ThreadStart(ChatProcess));//相当于receive
thread.Start();
}
catch(Exception ee)
{statusBar2.Text=ee.Message;}
客户端
try
{
ChatServer=new IPEndPoint(IPAddress.Parse(textBox4.Text),Int32.Parse(textBox5.Text));
ChatSocket=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
ChatSocket.Connect(ChatServer);
statusBar1.Text=textBox1.Text+" has logoned on.Now begin to connect";
Thread thread=new Thread(new ThreadStart(ChatProcess));
thread.Start();
}
catch(Exception ee)
{statusBar1.Text=ee.Message;}
发送按钮：
.Send;
Code
try
{
Byte[] SentByte=new Byte[64];
string SentStr=textBox1.Text+"::::"+textBox3.Text+"\r\n";
SentByte=System.Text.Encoding.BigEndianUnicode.GetBytes(SentStr.ToCharArray());
AcceptedSocket.Send(SentByte,SentByte.Length,0);
textBox3.Clear();
}
catch
{statusBar2.Text="The connection has not existed!";}
断开按钮：
socket.Close();
Code
try
{
ChatSocket.Close();
AcceptedSocket.Close();
statusBar2.Text="The connection is disconnected!";
}
catch{statusBar2.Text="The connection has not existed!";}
2 TcpClient方式
连接按钮：
服务器：Tcplistener()--->listener.Start();
客户端：TcpClient()--->tcpClient.Connect();
新建一个线程thread，绑定receive函数
thread.Start();
服务器
try
{
listener = new TcpListener(IPAddress.Parse(textBox1.Text), Int32.Parse(textBox2.Text));
listener.Start();
toolStripStatusLabel1.Text = "等待连接";
Thread thread = new Thread(new ThreadStart(Receive));
thread.Start();
}
catch(Exception ee)
{
toolStripStatusLabel1.Text =ee.Message;
}
客户端
try
{
tcpClient = new TcpClient();
tcpClient.Connect(textBox1.Text, Int32.Parse(textBox2.Text));
toolStripStatusLabel1.Text = "连接上。";
Thread thead = new Thread(new ThreadStart(receive));
thead.Start();
}
catch (Exception ee)
{
toolStripStatusLabel1.Text = ee.Message;
}
//receive函数
服务器：listener.AcceptSocket();
if(acceptSocket连接上)
{while循环接收，networkstream(acceptsocket)，netstream.Read}
catch{报警，断开，重新监听}
客户端:
netstream = tcpClient.GetStream
.Read
服务器
AcceptSocket = listener.AcceptSocket();
try
{
if(AcceptSocket.Connected)
{
toolStripStatusLabel1.Text = "建立连接";
while(!needControl)
{
netStream = new NetworkStream(AcceptSocket);
byte[] bytes = new byte[64];
netStream.Read(bytes, 0, bytes.Length);
string str = System.Text.Encoding.ASCII.GetString(bytes);
Invoke(new Action<string>(delegate(string aa) { richTextBox1.AppendText(aa); })
, str);
}
}
}
catch (Exception ee)
{
Invoke(new Action<string>(delegate(string aa)
{ toolStripStatusLabel1.Text =aa; })
, ee.Message);
}
客户端
try
{
if (tcpClient.Connected)
{
while (!needControl)
{
byte[] bytes = new byte[64];
netStream = tcpClient.GetStream();
netStream.Read(bytes, 0, bytes.Length);
string str = System.Text.Encoding.ASCII.GetString(bytes);
Invoke(new Action<string>(delegate(string aa) { richTextBox1.AppendText(aa); })
, str);
}
}
}
catch(Exception ee)
{
Invoke(new Action<string>(delegate(string aa) { toolStripStatusLabel1.Text = aa; })
, ee.Message);
}
发送按钮：
通过networkstream发送
服务器来自acceptsocket，客户端来自tcpClient.GetStream()
服务器
try
{
netStream = new NetworkStream(AcceptSocket);
string str = richTextBox2.Text + "\r\n";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(str);
netStream.Write(bytes, 0, bytes.Length);
netStream.Flush();
richTextBox2.Text = null;
}
catch (Exception ee)
{
toolStripStatusLabel1.Text = ee.Message;
}
客户端
try
{
netStream = tcpClient.GetStream();
string str = richTextBox2.Text + "\r\n";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(str);
netStream.Write(bytes, 0, bytes.Length);
netStream.Flush();
richTextBox2.Text = null;
}
catch (Exception ee)
{
toolStripStatusLabel1.Text = ee.Message;
}
断开按钮：
服务区关闭acceptsocket,listener
客户端关闭tcpClient
