Treat visual representation of integer as hex for placement in guid

We have an obsolete requirement to store what has recently transferred identifier values intto a type guidfor use in types of agnostic ID attributes (mostly old code that used the "globally unique" part guidto contain all possible identifiers in one column / field) .

In connection with this requirement needed to implement integer identifier entites in guida human-readable way . This is important and is currently what prevents me from working directly with byte values.

I currently have the following:

    public static byte[] IntAsHexBytes(int value)
    {
        return BitConverter.GetBytes(Convert.ToInt64(value.ToString(), 16));
    }

    public static Guid EmbedInteger(int id)
    {
        var ib = IntAsHexBytes(id);

        return new Guid(new byte[]
            {
                0,0,0,0,0,0,1,64,ib[7],ib[6],ib[5],ib[4],ib[3],ib[2],ib[1],ib[0]
            });
    }

int (value.ToString()), long (Convert.ToInt64(value.ToString(), 16)) long byte[] guid .

, int 42, 42 long, 66, 66 , guid :

"00000000-0000-4001-0000-000000000042"
