How to handle NetworkStream.BeginRead

Question

I read that TCP ensures the order of arrival of packets, but does not ensure that they are complete.
I also read that a system to solve this problem would be to first send the packet size and then read up until receiving a full package, but I do not understand how to implement such a system.

Solution 1

You have to thing about that TCP is like a pipe where data can be transported in. On top of that, you can implement what ever protocol or message system you like.

Say you what to send and receive a file. Then you have to tell the receiver some information about that file you will sent. It can be file name, create date/time and the size of the file.
When the receiver knows about that info, it will know how to interpret the data received.

See how HTTP protocol[^] is built up. Its been used for many years now.

i need to know how to implement a system that ensure i received full message with async read

Avoid async operation as threads are much more robust.

To ensure to receive all data, you call NetworkStream.BeginRead when you are done in the callback method. This tell that you are ready to receive more data. When there is no more data, callback method it not called.
See NetworkStream.EndRead
