       直接上代码，简单明了。

 

        /// <summary>
        ///     返回MD5
        /// </summary>
        /// <param name="input"></param>
        /// <returns></returns>
        public string Md5(string input)
        {
            MD5 md5Hash = MD5.Create();
            byte[] data = md5Hash.ComputeHash(Encoding.UTF8.GetBytes(input));


            StringBuilder sBuilder = new StringBuilder();


            for (int i = 0; i < data.Length; i++)
            {
                sBuilder.Append(data[i].ToString("x2"));
            }


            return sBuilder.ToString();
        }
