Why is this outputting 0 instead of throwing an error

byte b = 255; b += 1; Console.Write(b); // 0 Any answer is appreciated.

Nick error is only thrown in checked context , otherwise it truncates the higher order bits as this article says, https://docs.microsoft.com/en-us/dotnet/api/system.overflowexception?view=net-5.0

Rushikesh I appreciate the answers that you've given, but this thread has nothing to do with Java if you take a look at the tag.

Byte can only have max 255. sbyte can have -128-128. Use int or long.

Byte highest value is just 127 to -128🤔 but it can go to 255 266 is out of range according to file sizes
