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

Answer 1

TCP itself does not have any ways to define "end of data" condition. This is responsibility of application level portocol.

For instance see HTTP request description:

A client request (consisting in this case of the request line and only one header field) is followed by a blank line, so that the request ends with a double newline

So, for request end of data is determined by two newline sequences. And for response:

Content-Type specifies the Internet media type of the data conveyed by the HTTP message, while Content-Length indicates its length in bytes.

The response content size is specified in header before data. So, it's up to you how to encode amount of data transferred at once - it can be just first 2 or 4 bytes in the beginning of the data holding total size to read or more complex ways if needed.
