First of all I would like to thank you for taking the time to respond to my question. However, whilst that seems to cater for packets not being "fully-read", however, what I need to do is ensure that all data is received, by either slowing down the data transfer or somehow else...
There must be a solution to fully receive all the sent bytes, or implement the data transfer otherwise. Any help that will ensure that data is fully-read, is greatly appreciated!
In the mean time I would still like to thank you for taking the time to reply!

if you look at the read method it returns you an integer which represents the number of bytes that were actually read.
sometimes a read will only read a few bytes (depending on the packet structure with your TCP stream).
For this reason most people use a protocol that is either fixed size or includes deliniaters so that they can figure out when they have read a "full packet"
eg:
int bytesread = stream.Read(0, buffer, buffer.Length);
I can be told that only 1 byte was read. If I am reading a 256 byte packet ...
int count = 0;
byte [] buffer = new byte[256];
byte [] packet = new byte[256];
while(true) {
int bytesread= stream.Read(0, buffer, buffer.Length);
if(count + bytesread <=255) {
count += bytesread;
Array.Copy(packet, count, buffer, 0, bytesread);
if(count == 255) {
ProcessMessage(packet);
count = 0;
}
}
if(count + bytesread > 255) {
int touse = 255 - count;
Array.Copy(packet, count, buffer, 0, touse);
ProcessMessage(packet);
count = 0;
Array.Copy(packet, count, buffer, bytesread - touse);
}
}
