Question

I have an application that requires manipulating nybbles and possibly even individual bits at a time. Is there a library in C# that can help me?

Answer 1

You can use BitVector32 to manipulate bits in a 32 bit integer and BitArray to have an array of bits representing a set of boolean variables.

Also, it’s pretty easy to write a couple functions to manipulate individual bits:

public bool GetBitValue(int integer, int bit) {
    return (integer & (1 << bit)) != 0; 
}

public bool SetBitValue(ref int integer, int bit, bool value) {
    if (value)
        integer |= 1 << bit;
    else
        integer &= ~(1 << bit);
}
