"ORing" two bytes together

Question

I need to take two bytes and OR them together, a rather simple task. However, I do not know the proper syntax to OR the two bytes together.

 byte First = 0x03;
 byte Second = 0x15;

 //Need to or Them
 byte Result = First || Second; //This syntax does not work in C#

Did you read the documentation? You're using the wrong operator. `||` is a *logical* OR. You're looking for `|` which is a bitwise OR. — tnw, Aug 19 '14 at 15:17

|| is a logical or not bitwise so you need:

byte Result = (byte) (First | Second);
