Hello guys, can you explain me how to send a file as a string through socket from server to client side and convert the string back into the original file on the client side for further use.

Use System.Net.Sockets.TcpListener and System.Net.Sockets.TcpClient; this is most convenient way of using sockets for such purpose. Why raw sockets? A higher-level way with using classical remoting or WCF (self-hosted) would also work. A parameter of service contract method will be a file content (as string, if you want, but prefer encoding it the an array of bytes using UTF-8, for performance sake).

Solution 1

1. Why send it as a string? Is there any reason why you can't just send it as binary? Maybe need to prefix with a few bytes to give file size so that recipient know when binary file ends.

2. If you need to send a string, maybe convert binary data to text using Base64 encoding / decode it back at the other end.

Excellent response. My vote of 5!

Agree, a 5. One note: as a string without base64 encoding is also possible, can be just UTF-8 (UTF-16 less practical due to volume). Using raw TCP socket imposes no limitation.
