Get, Set, Read, converts bitwise in Short type value in C#

Question

I have a short value X:

short X=1;  //Result in binary: 0000000000000001 

1. I need to split them into an array and set the bits (say bit 6 and 10) //Result in binary: 0000001000100001
2. I need to convert it back to short X value.

How can I do it painlessly? Could you please help?

Answer 1

If what you are referring to is a very basic encryption, then perhaps using the XOR (^) operator would be better suited for your needs.

short FlipBytes(short original, params int[] bytesToSet)
{
    int key = 0;
    foreach (int b in bytesToSet)
    {
        if (b >= 0 && b < 16)
        {
            key |= 1 << b;
        }
    }

    return (short)(original ^ key);
}

This method will both set and reset the bytes that you desire. For example:

short X = 1;
short XEncrypt = FlipBytes(X, 6, 10);
short XDecrypt = FlipBytes(XEncrypt, 6, 10);

// X        = 1    , Binary = 0000000000000001
// XEncrypt = 1089 , Binary = 0000010001000001
// XDecrypt = 1    , Binary = 0000000000000001
