C# Bitwise With Integers

Question

I am trying to preform a simple bitwise statement to see if a user has security. It seems to be ok until i introduce variables.

This Works: byte test = 1 & 3.

Won't work: byte a = 1; byte b = 3; byte test = a & b;

Is there anyway that I can get this to work?

The error I get is: Cannot implicitly convert type 'int' to 'byte'. An explicit conversion exists (are you missing a cast?) — Trent Stewart

That error actually tells you 1) what's wrong, and 2) what to do about it. — user555045

I've never had to cast something in C# i'm still learning. But next time i'll know what to do :) — Trent Stewart

You need to cast it back to a byte as a bitwise AND will return an int, so do this:

byte a = 1; byte b = 3; byte test = (byte)(a & b);
