我有一个小问题,我不知道如何导入我的程序要读取的 xml 文档,然后验证字符串(真/假),如果是真的保存它们。该程序由程序类、paymentImporter 类和接口类组成。我知道我只需要更改 paymentImporter 类即可使其正常工作。代码如下:

paymentImporter 类:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WsPreInterviewTest
{

    public class XmlPaymentImporter : IPaymentImporter
    {
        public XmlPaymentImporter(IDatabaseProvider service_provider)
        {
            //import file

            throw new NotImplementedException();
        }

        public bool ReadFile(string file_path, List<string> errs)
        {

            //read file for validation

            throw new NotImplementedException();
        }

        public bool SaveAll()
        {
            //save if validation ok

            throw new NotImplementedException();
        }
    }
}

Interface Class:




public class Person
{
    public int Recno { get; set; }
    public string Name {get;set;}        
}

public class Payment
{
    public int PersonRecno { get; set; }
    public string Currency { get; set; }
    public decimal Amount { get; set; }
    public string Narrative { get; set; }

}

interface IPaymentImporter
{
    bool ReadFile(string file_path, List<string> errs);
    bool SaveAll();
}

public interface IDatabaseProvider
{
    DatabaseRepository GetDataRepository();
}

public abstract class DatabaseRepository
{
    public DatabaseRepository()
    {

    }


    /// <summary>
    /// returns null if person is not known
    /// </summary>
    /// <param name="name"></param>
    /// <returns></returns>
    public abstract Person FindPerson(string name);

    public abstract bool SavePayment(Payment payment);


}

}

程序类:

class Program
{
    static void Main(string[] args)
    {
        IDatabaseProvider _service_provider = null;
        string example_file = "ExampleFile.xml";
        XmlPaymentImporter importer = new XmlPaymentImporter(_service_provider);
        List<string> errors = new List<string>();
        if (importer.ReadFile(example_file, errors))
        {
            if (!importer.SaveAll())
                Console.WriteLine("Problem saving records");
        }
        else
        {
            Console.WriteLine("Problem With File");
            foreach (string s in errors)
                Console.WriteLine(s);
        }

用相应的 xml 类型装饰器装饰你的PersonPayment类。[Serializable()]然后只需将您的 xml 文档反序列化为这些类并捕获异常。如何反序列化 XML 文档

我看到的唯一问题是您的课程中没有Person字段Payment。您尚未提供要反序列化的 xml,但如果您将 person 元素作为 payment 的子元素,则具有相同的类结构将使您更容易。您只需调用 Deserialize() 即可获得完整的数据结构。
