在控制台应用程序中,无法将值“”分析为“Boolean”类型

我正在将wcf服务消费到控制台应用程序中。我想根据帐号检索帐户信息。当我输入帐号时,它可以无任何错误地使用该方法,但我在控制台应用程序中遇到以下错误。

:'格式化程序在尝试反序列化消息时引发异常:尝试反序列化参数时出错 http://tempuri.org/:AccountBalanceCheekResult . InnerException消息为“反序列化System类型的对象时出错。”。布尔值。无法将值“”分析为“Boolean”类型。有关详细信息,请参阅InnerException。”

这是课程。

[DataContract]
    public class AccountBalanceRequest : Current_Account_Details
    {
        string account_number;

        [DataMember]
        public string Account_Number
        {
            get { return account_number; }
            set { account_number = value; }
        }
    }
}

下面是实现,我在ADO中没有发现任何错误。NET代码。

   public AccountBalanceRequest AccountBalanceCheek(AccountBalanceRequest accountNumber)
        {
            using (SqlConnection conn = new SqlConnection(ConnectionString))
            {
                conn.Open();

                var cmd = new SqlCommand("SELECT * FROM Current_Account_Details WHERE Account_Number = '" + accountNumber.Account_Number + "'", conn);


                cmd.CommandType = CommandType.Text;

                var reader = cmd.ExecuteReader();
                //read the result of the execute command.
                while (reader.Read())
                {
                    //assuming that your property is the same as your table schema. refer to your table schema Current_Account_Details

                    accountNumber.Account_Number = reader["Account_Number"].ToString();
                    accountNumber.Account_Creation_Date = reader["Account_Creation_Date"].ToString();

                    accountNumber.Account_Type = reader["Account_Type"].ToString();
                    accountNumber.Branch_Sort_Code = reader["Branch_Sort_Code"].ToString();
                    accountNumber.Account_Fees = reader["Account_Fees"].ToString();
                    accountNumber.Account_Balance = reader["Account_Balance"].ToString();
                    accountNumber.Over_Draft_Limit = reader["Over_Draft_Limit"].ToString();
                }
                return accountNumber;
            }
        }

这是控制台窗口代码。

  public static void Balance()
        {
            MyService.HalifaxCurrentAccountServiceClient currentAccount = new MyService.HalifaxCurrentAccountServiceClient("NetTcpBinding_IHalifaxCurrentAccountService");
            MyService.AccountBalanceRequest cs = new MyService.AccountBalanceRequest();


            string AccountNumber;


            Console.WriteLine("\nEnter your Account Number--------:");
            AccountNumber = Console.ReadLine();
            cs.Account_Number = AccountNumber;
            // MyService.AccountBalanceRequest cs1 = currentAccount.AccountBalanceCheek(AccountNumber);



           if (currentAccount.AccountBalanceCheek(cs))**//Error on this line**
            {

                    Console.WriteLine("Your Account Number is :" + cs.Account_Number);
                    Console.WriteLine("Your Account Type :" + cs.Account_Balance);
                    Console.WriteLine("Your Account Account Fee :" + cs.Account_Fee);
                    Console.WriteLine("Your Account Balance:" + cs.Account_Balance);
                    Console.WriteLine("Your Account Over Draft Limit :" + cs.Over_Draft_Limit);

                    Console.Write("--------------------------");
                    Console.ReadLine();
                    //Console.Clear();


           }

        }

这是我运行应用程序时的屏幕截图。
