额外＆＃34;指定＆＃34;代理类中的字段

Question

有一个WCF Web服务和Web服务的客户端。 Web服务包含一些带有一些参数的方法。

Web服务合同：

namespace WcfPaymentRegistryService
{
    [ServiceContract]
    public interface UsrIPaymentRegistryService
    {
        #region business methos region

        [OperationContract]
        string TestConnection();

        #endregion

        #region business methos region

        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped)]           
        [OperationContract]
        string GetPaymentRegistry(string debtorName, string debtorSurname, string debtorMiddleName, DateTime dateBegin, DateTime dateEnd);

        #endregion
    }
}

Web服务实现：

namespace WcfPaymentRegistryService
{
    public class UsrPaymentRegistryService : UsrIPaymentRegistryService
    {        
        private string clientSection;
        private string paymentSection;

        #region business methos region

        string UsrIPaymentRegistryService.GetPaymentRegistry(string debtorName, string debtorSurname, string debtorMiddleName, 
            DateTime dateBegin, DateTime dateEnd)
        {
            var userConnection = (UserConnection)HttpContext.Current.Session["UserConnection"];
            var resultXml = "";

            var selectPaymentsRegister = (Select)new Select(userConnection)
                .Column("c", "Surname").As("Surname")
                .Column("c", "GivenName").As("Name")
                .Column("c", "MiddleName").As("MiddleName")
                .Column("c", "Name").As("FullName")
                .Column("c", "Phone").As("Phone")
                .Column("c", "Address").As("Address")
                .Column("up", "UsrPaymentSum").As("Amount")
                .Column("up", "UsrPaymentDate").As("AmountDate")
                .From("UsrPayments").As("up")
                .Join(JoinType.Inner, "Contact").As("c")
                .On("up", "UsrDebtorId").IsEqual("c", "Id")
                .Where("c", "Surname").IsEqual(Column.Parameter(debtorSurname))
                .And("c", "GivenName").IsEqual(Column.Parameter(debtorName))
                .And("c", "MiddleName").IsEqual(Column.Parameter(debtorMiddleName))
                .And("up", "UsrPaymentDate").IsGreaterOrEqual(Column.Parameter(dateBegin))
                .And("up", "UsrPaymentDate").IsLessOrEqual(Column.Parameter(dateEnd)) 

                as Select;

            using (DBExecutor dbExecutor = userConnection.EnsureDBConnection())
            {
                using (IDataReader reader = selectPaymentsRegister.ExecuteReader(dbExecutor))
                {
                    while (reader.Read())
                    {
                        clientSection =
                            "<Client>\n" +
                                "<Name>" + reader["Name"].ToString() + "</Name>\n" +
                                "<Phone>" + reader["Phone"].ToString() + "</Phone>\n" +
                                "<Address>" + reader["Address"].ToString() + "</Address>\n" +
                            "</Client>";

                        paymentSection +=
                            "<Payment>\n" + 
                                "<Amount>"+ reader["Amount"].ToString() + "</Amount>\n" +
                                "<Date>" + reader["AmountDate"].ToString() + "</Date>\n" +
                            "</Payment>\n";
                    }
                    resultXml = "<xml>\n" + clientSection + "<Payments>\n" + paymentSection + "</Payments>\n</xml>";
                }
            }
            return resultXml;
        }

        #endregion

        #region common methods region

        string UsrIPaymentRegistryService.TestConnection()
        {
            return "Test connection is successful";
        }

        #endregion
    }
}

在方法GetPaymentRegistry(...)中，我添加了参数DateTime dateBegin和DateTime dateEnd。我从WSDL生成了一个代理类，发现该方法添加了额外的参数dateBeginSpecified bool和bool dateEndSpecified。

如何禁用其他参数的生成？

我将非常感谢这些信息。谢谢大家。
