How to use C#'s ternary operator with two byte values?

Question

There doesn't seem to be a way to use C#'s ternary operator on two bytes like so:

byte someByte = someBoolean ? 0 : 1;

That code currently fails to compile with "Cannot convert source type 'int' to target type 'byte'", because the compiler treats the numbers as integers. Apparently there is no designated suffix to indicate that 0 and 1 are bytes, so the only workarounds are to (a) cast the result into a byte or (b) to use an if-else control after all.

Any thoughts?

Answer 1

byte someByte = someBoolean ? (byte)0 : (byte)1;

The cast is not a problem here, in fact, the IL code should not have a cast at all.

Edit: The IL generated looks like this:

L_0010: ldloc.0          // load the boolean variable to be checked on the stack
L_0011: brtrue.s L_0016  // branch if true to offset 16
L_0013: ldc.i4.1         // when false: load a constant 1
L_0014: br.s L_0017      // goto offset 17
L_0016: ldc.i4.0         // when true: load a constant 0
L_0017: stloc.1          // store the result in the byte variable

Answer 2

You could always do:

var myByte = Convert.ToByte(myBool);

This will yield myByte == 0 for false and myByte == 1 for true.
