跪求大腿用C# 代码重构该方法

[迷茫的Buffer]

public static String sign(String accessSecret, String stringToSign) throws Exception
{
javax.crypto.Mac mac = javax.crypto.Mac.getInstance("HmacSHA1");
mac.init(new javax.crypto.spec.SecretKeySpec(accessSecret.getBytes("UTF-8"), "HmacSHA1"));
byte[] signData = mac.doFinal(stringToSign.getBytes("UTF-8"));
return new sun.misc.BASE64Encoder().encode(signData);
}

[正怒月神]

 public static string HmacSha1Sign(string secret, string strOrgData)
        {
            var hmacsha1 = new HMACSHA1(Encoding.UTF8.GetBytes(secret));
            var dataBuffer = Encoding.UTF8.GetBytes(strOrgData);
            var hashBytes = hmacsha1.ComputeHash(dataBuffer);
            return Convert.ToBase64String(hashBytes);
        }

已解决,谢谢
