Java写法改成C#

[【Help】]

[code=csharp]
private static byte[] MD5(String data) throws IOException {
  byte[] bytes = null;
  try {
   MessageDigest md = MessageDigest.getInstance("MD5");
   bytes = md.digest(data.getBytes(Constants.CHARSET_UTF8));
  } catch (GeneralSecurityException gse) {
   String msg = getStringFromException(gse);
   throw new IOException(msg);
  }
  return bytes;
 }

 private static String B(byte[] bytes) {
  StringBuilder sign = new StringBuilder();
  for (int i = 0; i < bytes.length; i++) {
   String hex = Integer.toHexString(bytes[i] & 0xFF);
   if (hex.length() == 1) {
    sign.append("0");
   }
   sign.append(hex.toUpperCase());
  }
  return sign.toString();
 }

md5算法？这个不用换了吧？直接C#代码就可以

public class Digest
    {
        public static string MD5Of(string text)
        {
            return MD5Of(text, Encoding.UTF8);
        }
        public static string MD5Of(string text, Encoding enc)
        {
            return HashOf<MD5CryptoServiceProvider>(text, enc);
        }
        public static string SHA1Of(string text)
        {
            return SHA1Of(text, Encoding.UTF8);
        }
        public static string SHA1Of(string text, Encoding enc)
        {
            return HashOf<SHA1CryptoServiceProvider>(text, enc);
        }

        public static string SHA384Of(string text)
        {
            return SHA384Of(text, Encoding.UTF8);
        }
        public static string SHA384Of(string text, Encoding enc)
        {
            return HashOf<SHA384CryptoServiceProvider>(text, enc);
        }

        public static string SHA512Of(string text)
        {
            return SHA512Of(text, Encoding.UTF8);
        }
        public static string SHA512Of(string text, Encoding enc)
        {
            return HashOf<SHA512CryptoServiceProvider>(text, enc);
        }

        public static string SHA256Of(string text)
        {
            return SHA256Of(text, Encoding.UTF8);
        }
        public static string SHA256Of(string text, Encoding enc)
        {
            return HashOf<SHA256CryptoServiceProvider>(text, enc);
        }

        public static string HashOf<TP>(string text, Encoding enc)
            where TP : HashAlgorithm, new()
        {
            return BitConverter.ToString(HashBytes<TP>(text, enc)).Replace("-", "");
        }
        public static byte[] HashBytes<TP>(string text, Encoding enc)
            where TP : HashAlgorithm, new()
        {
            var buffer = enc.GetBytes(text);
            var provider = new TP();
            return provider.ComputeHash(buffer);
        }
    }

按你的java代码，MD5Of(string text)这个方法就可以了，转换结果也是大写的

引用 2 楼 starfd 的回复:

public static String encryptHMAC(String data, String key) { if (Strings.isNullOrEmpty(data)) { return null; } byte[] bytes = encryptHMAC(data.getBytes(), key); return byteArrayToHexString(bytes); }这种呢？

这个就不知道你具体是哪种HMAC了 微软默认提供了 HMACMD5 HMACSHA1 HMACSHA256 HMACSHA384 HMACSHA512 HMACRIPEMD160
