如何将XML反序列化为List <object> </object>

标签： c# xml asp.net-mvc asp.net-mvc-3 wcf

我尝试创建WCF，返回值为XML。 当我尝试将xml文件反序列化为对象时，我有错误。

这是我的反序列化文件的代码

我的控制器

//serialize request to wcf//    
var requestXML = Lib.Serializer.ObjectSerializer.Serialize(request);
//get response from wcf//
var XMLResult = Lib.Net.Http.Post(requestXML,"http://localhost:53721/RoomRate.svc/RoomRates", 60);
//deserialize xml file to object//
var response = Lib.Serializer.ObjectSerializer.Deserialize<List<RoomRatesResponses>>(XMLResult);

我的反序列化xml

的类 
public static T Deserialize<T>(string xml)
{
    T result;
    XmlSerializer ser = new XmlSerializer(typeof(T));
    using (TextReader tr = new StringReader(xml))
    {
        result = (T)ser.Deserialize(tr);
    }
    return result;
}

我的对象模型

public class RoomRatesResponses
{
    public List<RoomRateResponse> ListRoomRateResponse { get; set; }

    public RoomRatesResponses()
    {
        ListRoomRateResponse = new List<RoomRateResponse>();
    }
}

public class RoomRateResponse
{
    public string ErrorMessage { get; set; }
    public bool OperationSuccess { get; set; }
    public int Allotment { get; set; }
    public bool Breakfast { get; set; }
    public DateTime CheckInDate { get; set; }
    public bool CloseSelling { get; set; }
    public double CommissionPct { get; set; }
    public string CurrCode { get; set; }
    public bool FreeSell { get; set; }
    public int RoomRateId { get; set; }
    public string RoomType { get; set; }
    public double SingleRate { get; set; }
    public double TripleRate { get; set; }
    public double TwinDoubleRate { get; set; }
}

当我反序列化我的xml时，我有这样的错误

  

<ArrayOfRoomRateResult xmlns=''>没有预料到。        描述：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪了解更多信息   有关错误的信息以及它在代码中的起源。

     

异常详细信息：System.InvalidOperationException：<ArrayOfRoomRateResult xmlns=''>未被预期。

如何解析我的xml文件？

以下是解决问题所需的虚拟代码。它显示了序列化如何在这里工作，反向是要进行反序列化，注意类和变量名称：

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Threading;
using System.Xml.Serialization;

namespace Code.Without.IDE
{
    //http://stackoverflow.com/questions/20697928/how-to-deserialize-xml-to-listobject

            RoomRateResult rs1 = new RoomRateResult
                                        {
                                            ErrorMessage = string.Empty,
                                            OperationSuccess = true,

                                            TripleRate = 150d,
                                            TwinDoubleRate = 150d
                                        };

            RoomRateResult rs2 = new RoomRateResult
                                        {
                                            ErrorMessage = string.Empty,

                                            CloseSelling = false,
                                            CommissionPct = 2.0d,
                                            CurrCode = "USD",
                                            FreeSell = true,
                                            RoomRateId = 110,
                                            RoomType = "Mega",
                                            SingleRate = 90d,
                                            TripleRate = 140d,
                                            TwinDoubleRate = 150d
                                        };

            ArrayOfRoomRateResult.Add(rs1);
            ArrayOfRoomRateResult.Add(rs2);

            XmlSerializer ser = new XmlSerializer(typeof(List<RoomRateResult>));
            TextWriter writer = new StreamWriter("serl.xml");
            ser.Serialize(writer, ArrayOfRoomRateResult);
            writer.Flush();
            writer.Close();
        }
    }

    [Serializable]
    public class RoomRateResult
    {
        public string ErrorMessage { get; set; }
        public bool OperationSuccess { get; set; }
        public int Allotment { get; set; }

        public double TripleRate { get; set; }
        public double TwinDoubleRate { get; set; }
    }
}

序列化给出：

<?xml version="1.0" encoding="utf-8"?>

    <RoomType>Mega</RoomType>

    <TripleRate>140</TripleRate>
    <TwinDoubleRate>150</TwinDoubleRate>
  </RoomRateResult>
</ArrayOfRoomRateResult>

如果你不想像Abhinav所说的那样出于某种原因重命名你的类，你可以创建自己的列表来实现 IXmlSerializable ：

[XmlRoot(ElementName = "ArrayOfRoomRateResult")]
public class MyList : List<RoomRateResponse>, IXmlSerializable
{
    public XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(XmlReader reader)
    {
        var serializer = new XmlSerializer(typeof(RoomRateResponse));
        var wasEmpty = reader.IsEmptyElement;
        reader.Read();
        if (wasEmpty)
            return;
        while (reader.NodeType != XmlNodeType.EndElement)
        {
            var item = (RoomRateResponse)serializer.Deserialize(reader);
            Add(item);
        }
        reader.ReadEndElement();
    }

    public void WriteXml(XmlWriter writer)
    {
        var serializer = new XmlSerializer(typeof(RoomRateResponse));
        foreach (var val in this)
        {
            serializer.Serialize(writer, val);
        }
    }
}

您还需要将属性添加到 RoomRateResponse ：

[XmlRoot(ElementName = "RoomRateResult")]
public class RoomRateResponse
{
    //...
}

现在您的序列化按预期工作：

//...
var response = Lib.Serializer.ObjectSerializer.Deserialize<MyList>(xml);
