直接上方法

public string ConvertToMd5(string password)

        {

            if (string.IsNullOrEmpty(password))

            {

                return string.Empty;

            }

            using (MD5CryptoServiceProvider MD5 = new MD5CryptoServiceProvider())

            {

                return BitConverter.ToString(MD5.ComputeHash(Encoding.UTF8.GetBytes(password)),0).Replace("-", string.Empty);

            }

        }
