MD5

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);
            }
        }
