HMAC C# and JavaScript

在获取C#和Javascript以生成相同的HMAC:时遇到问题

C#：

string data = String.Format("{0}{1}{2}{3}{4}{5}", APPId, requestHttpMethod, requestUri, requestTimeStamp, nonce, requestContentBase64String);
        var secretKeyBytes = Convert.FromBase64String(sharedKey);
        byte[] signature = Encoding.UTF8.GetBytes(data);
        using (HMACSHA256 hmac = new HMACSHA256(secretKeyBytes))
        {
            byte[] signatureBytes = hmac.ComputeHash(signature);                
            return (incomingBase64Signature.Equals(Convert.ToBase64String(signatureBytes), StringComparison.Ordinal));
        }

Javascript：

var signatureRawData = "".concat(appId, requestHttpMethod, requestUri, requestTimeStamp, nonce, requestContentBase64String);
var hash = CryptoJS.HmacSHA256(signatureRawData, apiKey);
var hashInBase64 = CryptoJS.enc.Base64.stringify(hash);

c代码中的apiKey在哪里？它是sharedKey吗？sercretKeyBytes是字符串、char[]还是byte[]？我怀疑secrtetKeyBytes正被转换为字符串，这就是问题的原因。
