How to get all data from NetworkStream

Question

I am trying to read all data present in the buffer of the Machine connected through TCP/IP but i don't know why i am not getting all data ,some data is getting Missed. Here is the code that i am using ..

using (NetworkStream stream = client.GetStream())
{
    byte[] data = new byte[1024];
    int numBytesRead = stream.Read(data, 0, data.Length);
    if (numBytesRead > 0)
    {
       string str= Encoding.ASCII.GetString(data, 0, numBytesRead);
    }
}

Please tell me what i am missing to get all the data from the machine. Thanks in advance..

Answer 1

for my scenario, the message itself was telling the length of subsequent message. here is the code

 int lengthOfMessage=1024;
 string message = "";
 using (MemoryStream ms = new MemoryStream())
 {
      int numBytesRead;
      while ((numBytesRead = memStream.Read(MessageBytes, 0, lengthOfMessage)) > 0)
      {
            lengthOfMessage = lengthOfMessage - numBytesRead;
            ms.Write(MessageBytes, 0, numBytesRead);
      }
      message = Encoding.ASCII.GetString(ms.ToArray(), 0, (int)ms.Length);
 }
