public static byte[] StringToByteArray(String hex)

int NumberChars = hex.Length;
byte[] bytes = new byte[NumberChars / 2];
for (int i = 0; i < NumberChars; i += 2)
bytes[i / 2] = Convert.ToByte(hex.Substring(i, 2), 16);
return bytes;
}
問題：c#的如何改成像上面js的那樣，用 a.getHMAC("B64")的？

byte[] hashmessage = hmacsha1.ComputeHash(Encoding.UTF8.GetBytes("abc"));var b64 = Convert.ToBase64String(hashmessage);
得出的結果跟js計算的一致

我的結果是：8L9Q2JUrEVgn6zg15xObcJIL1c8=，不同啊？
