Расчет CRC16 в C#?

Question

У меня есть код c, который я использовал для расчета crc16, может ли любой конвертировать его в C#?

static const unsigned short crc16tab[256]= { 
0x0000,0x1021,0x2042,0x3063,0x4084,0x50a5,0x60c6,0x70e7,

Brute перевод от C до C# будет выглядеть следующим образом:

public static class CRCHelper 
    { 
     private static ushort[] crc16tab = new ushort[256] { 
     0x0000,0x1021,0x2042,0x3063,0x4084,0x50a5,0x60c6,0x70e7,
