TcpClient reading problem

[David Dvali]

Hello.
I wnat to read some data from server, I'm using following code:
----------------------------------------------------------------------------------------
TcpClient cl = new TcpClient();
cl.Connect("Som eHost", 9000);

NetworkStream networkStream = cl.GetStream();

if (!networkStream .CanRead)
return;
byte[] myReadBuffer = new byte[1024];
String myCompleteMessa ge = "";
int numberOfBytesRe ad = 0;

do
{
numberOfBytesRe ad = networkStream.R ead(myReadBuffe r, 0,
myReadBuffer.Le ngth);
myCompleteMessa ge = String.Concat(m yCompleteMessag e,
Encoding.ASCII. GetString(myRea dBuffer, 0, numberOfBytesRe ad));
}
while(networkSt ream.DataAvaila ble);

cl.Close();
----------------------------------------------------------------------------------------
When it executes lone:
numberOfBytesRe ad = networkStream.R ead(myReadBuffe r, 0,
myReadBuffer.Le ngth);
The applications just heng up:(
What I'm doing wrong?

Thank you.

Because it's trying to read something which is not available.

TCPClinet has a property called ReceiveTimeout which Gets or sets the
amount of time a TcpClient will wait to receive data once a read
operation is initiated.

Can you tell me how can I use unblocked sockets?
