C#实现java的DigestUtils.md5Hex加密方式

private static string Md5Hex(string data)
{
MD5CryptoServiceProvider md5 = new MD5CryptoServiceProvider();
byte[] dataHash = md5.ComputeHash(Encoding.UTF8.GetBytes(data));
StringBuilder sb = new StringBuilder();
foreach (byte b in dataHash)
{
sb.Append(b.ToString("x2").ToLower());
}
return sb.ToString();
}
