Gray code in .NET

Question

Is there a built in Gray code datatype anywhere in the .NET framework? Or conversion utility between Gray and binary? I could do it myself, but if the wheel has already be

Answer 1

Here is a C# implementation that assumes you only want to do this on non-negative 32-bit integers:

static uint BinaryToGray(uint num)
{
    return (num>>1) ^ num;
}

You might also like to read this blog post which provides methods for conversions in both directions, though the author chose to represent the code as an array of int containing either one or zero at each position. Personally I would think a BitArray might be a better choice.
