C# TCPClient - Data Mismatch

C# TCPClient - Data Mismatch

I need some help. I have a simple server-client application using C#
TCPClient
The problem that I am having is that when a client sends a message to
server, the server returns a 4 bytes response containing an number.
But, every 3 or 4 responses the bytes are in the same wrong place.
For example:
server response with a byte array containing an integer 243:
byte[0] => 243 byte[1] => 0 byte[2] => 0 byte[3] => 0
The client receives the 4 bytes as follows:
byte[0] => 0 byte[1] => 0 byte[2] => 243 byte[3] => 0
This is an integer number of 15925248 not 243.
Here's the snippet of server code. the code executes when client sends a
message:
byte[4] resp = new byte[4]; Buffer.BlockCopy(BitConverter.GetBytes(243),
0, resp, 0, 4); clientStream.Write(resp, 0, resp.Length);
clientStream.Flush();
Here's the snippet of client code to receive:
Byte[] rec = new Byte[4] {0xx0, 0x00, 0x00, 0x00}; if (netStream.CanRead)
{ int numberOfBytesRead = 0; do { numberOfBytesRead = netStream.Read(rec,
0, rec.Length); } while (netStream.DataAvailable); }
I have done the following: - verified that the server indeed is sending
the byte array correctly.
I don't know what am I doing wrong here. Or is there a bug in my code or not.
Please help me.
