JAVA MD5 加密 对应 c# MD5 加密

java：

1     public static String md5(String username, String password) throws NoSuchAlgorithmException {
2         MessageDigest md = MessageDigest.getInstance("MD5");
3 
4         md.update(username.getBytes());
5         md.update(password.getBytes());
6 
7         return new BigInteger(1, md.digest()).toString(16);
8     }

c#:

 1         public static string MD5Encode(string str)
 2         {
 3             var md5 = MD5.Create();
 4             var bs = md5.ComputeHash(Encoding.UTF8.GetBytes(str));
 5             var sb = new StringBuilder();
 6             foreach (byte b in bs)
 7             {
 8                 sb.Append(b.ToString("x2"));
 9             }
10             //所有字符转为小写
11             return sb.ToString().ToLower();
12         }
