Since Java bytes are signed values and I'm trying to establish a TCP socket connection with a C# program that is expecting the bytes to be unsigned.
I am not able to change the code on the C# portion.
How can I go about sending these bytes in the correct format using Java.
Thanks
No, Java bytes are signed values. In general C# bytes are unsigned. (You'd need the sbyte type to refer to signed bytes; I can't remember the last time I used sbyte.)
However, it shouldn't matter at all in terms of transferring data across the wire - normally you just send across whatever binary data you've got (e.g. what you've read from a file) and both sides will do the right thing. A byte with value -1 on the Java side will come through as a byte with value 255 on the C# side.
If you can tell us more about exactly what you're trying to do (what the data is) we may be able to help more, but I strongly suspect you can just ignore the difference in this case.
