Problems with ReadByte on a TCP/IP Client Stream

Question

Hello Does anyone have any experience using the ReadByte method on a TCP/IP client stream? The method does not return a -1 when I am at the end of a stream the code just hangs. Regards Dave

Hello Thanks for getting back to me. You are correct using a trycatch block will work but it is a work around for the problem. I am disappointed when thsings do not work as documented. In theory if there is nothing in the stream you should receive a -1 otherwise you get the char from the stream. However in the real world if there is nothing in the stream you get a exception which requires you to use a trycatch block as a work around. Well at leastI have found a way to get the code to work and I can move on to other things that my code needs to do. Regards Dave

While I don't have much experience doing any sort of TCP/IP coding does the code generate an exception?? if so you can use a try-catch block to catch it as the end of stream. It should throw an InvalidOperationException if you tried to read past the end of the stream.
