Why is this outputting 0 instead of throwing an error

Question

byte b = 255;
b += 1;

Console.Write(b);
// 0

Any answer is appreciated.

Answer 1

Nick error is only thrown in checked context , otherwise it truncates the higher order bits as this article says,

Answer 3

Rushikesh

byte in C# is an unsigned value

Answer 4

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.

Answer 5

In c#
sbyte - -128 to 127
Byte 0-255

Answer 6

Rushikesh

But can you explain why the integer didn't overflow

Answer 7

Nick iam talking about java
for just to know about byte size

Answer 8

That means your adding one to 255(heighest byte value)
Which is not possible

Answer 9

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

Answer 10

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

Answer 11

C# does not check overflow exceptions
like any other languages
