Hello:
I write a multithread c# socket server,it is a winform application,there is
a richtextbox control and button,when the button is click,the server begin
to listen the socket port,waiting for a incoming connection,the relative
code snipprt as following::
private IPAddress myIP=IPAddress.Parse("127.0.0.1");
private IPEndPoint myServer;
private Socket socket;
private Socket accSocket;
private System.Windows.Forms.Button button2;
private bool check;
private void button1_Click(object sender, System.EventArgs e)
{
check=true;
try
{
Thread thread =new Thread(new ThreadStart(accp));
thread.Start();
}
catch(Exception ee)
{
MessageBox.Show(ee.Message);
}
}
private void accp()
{
myServer=new IPEndPoint(myIP,Int32.Parse("20000"));
socket=new
Socket(AddressFamily.InterNetwork,SocketType.Strea m,ProtocolType.Tcp);
socket.Bind(myServer);
socket.Listen(50);
while(true)
{
try
{
accSocket=socket.Accept();
if(accSocket.Connected)
{
Thread thread=new Thread(new ThreadStart(round));
thread.Start();
}
}
catch(Exception ee)
{
MessageBox.Show(ee.Message);
}
}
}
private void round()
{
Byte[] rec=new Byte[1024];
NetworkStream acceptStream=new NetworkStream(accSocket);
int i=0;
while((i=acceptStream.Read(rec,0,rec.Length))!=0)
{
string
recMessage=System.Text.Encoding.Default.GetString( rec);
rec=new Byte[1024];
this.richTextBox1.AppendText(recMessage);
}
}
¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*.
¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*¡*
In order to test the server,I write a multithread client too,there is only
one button in the form,when it is clicked,four threads is generated to
connect the server simultaneously,each thread write one line to the server
socket.code as:
private IPAddress myIP;
private IPEndPoint myServer;
private Socket socket;
private void button1_Click(object sender, System.EventArgs e)
{
for(int i=0;i<4;i++)
{
Thread thread=new Thread(new ThreadStart(round));
thread.Start();
thread.Join();
}
}
private void round()
{
try
{
myIP=IPAddress.Parse("127.0.0.1");
myServer=new IPEndPoint(myIP,Int32.Parse("20000"));
socket=new
Socket(AddressFamily.InterNetwork,SocketType.Strea m,ProtocolType.Tcp);
socket.Connect(myServer);
NetworkStream netStream=new NetworkStream(socket);
Byte[] byteMessage=new Byte[640];
string sendMessage="´ó¼ÒºÃ£¡£¡£¡£¡!\r\n";
byteMessage=System.Text.Encoding.Default.GetBytes( sendMessage.ToCharArray())
;
// socket.Send(byteMessage,byteMessage.Length,0);
netStream.Write(byteMessage,0,byteMessage.Length);
netStream.Flush();
netStream.Close();
socket.Close();
}
catch(Exception ee)
{
MessageBox.Show(ee.Message);
}
}
As you can see,when I click the button in the client side,I should see four
lines is printed in the server side.but in fact,I can¡¯t,I can only see one
line,sometimes two or three lines,by my tracing,I found they always come
from the last several threads.if I modify the button click event in the
client as following(add sleep between the threads),it works well,that is I
can see four lines every time in the server:
private void button1_Click(object sender, System.EventArgs e)
{
for(int i=0;i<4;i++)
{
Thread thread=new Thread(new ThreadStart(round));
thread.Start();
thread.Join();
Thread.Sleep(100);
}
}
If I modify the timeout param of the sleep method to lower and lower, the
mentioned problem occur again.i also write a java multithread server, it
works well to the simuteneous thread connection.
Why c# socket server can¡¯t handle the simultaneous access?is it a bug?by
comparing the java server and c# server,I also found that the java server is
faster then c# server.
Any instruction?Thank you.

You do not have to repost you message over and over. As far as I see 6
messages from now you recieved an answer from community member, Henrik Dahl,
to your question. So why repost? Use the current thread to continue

sorry,the other questions is posted from other forums,maybe microsoft community and several others ,and i only post one time in every forum.i don't know why they come here,maybe you are the same forum.
