將xml反序列化為對象列表

Question

我正在嘗試將一些xml反序列化為對象列表。

我遇到麻煩的地方是Event對象中的輔助對象Resources沒有填充值。 對於更多的背景知識，這是一個統一的項目，我正在反序列化可能發生的隨機事件的列表。

以下是我正在測試的XML：

<?xml version='1.0'?>
<Events>
  <Event>
    <Description>
      this is a test
    </Description>
    <Reward>
        <Food>
          0
        </Food>
        <Energy>
          1
        </Energy>
        <Happiness>
          2
        </Happiness>
        <ShipHp>
          3
        </ShipHp>
        <Garbage>
          4
        </Garbage>
    </Reward>
    <Cost>
        <Food>
          0
        </Food>
        <Energy>
          1
        </Energy>
        <Happiness>
          2
        </Happiness>
        <ShipHp>
          3
        </ShipHp>
        <Garbage>
          4
        </Garbage>
    </Cost>
    <EventType>
      Good
    </EventType>
    <EventId>
      1
    </EventId>
  </Event>
  <Event>
    <Description>
      this is a test
    </Description>
    <Reward>
        <Food>
          0
        </Food>
        <Energy>
          1
        </Energy>
        <Happiness>
          2
        </Happiness>
        <ShipHp>
          3
        </ShipHp>
        <Garbage>
          4
        </Garbage>
    </Reward>
    <Cost>
        <Food>
          0
        </Food>
        <Energy>
          1
        </Energy>
        <Happiness>
          2
        </Happiness>
        <ShipHp>
          3
        </ShipHp>
        <Garbage>
          4
        </Garbage>
    </Cost>
    <EventType>
      Good
    </EventType>
    <EventId>
      1
    </EventId>
  </Event>
</Events>

以下是對象（事件和資源）：

public class Event {
    [XmlElement("Description")]
    public string Description { get; set; }

    [XmlElement("Reward")]
    public Resources Reward { get; set; }

    [XmlElement("Cost")]
    public Resources Cost { get; set; }

    [XmlElement("EventId")]
    public int EventId { get; set; }

    [XmlElement("EventType")]
    public string EventType { get; set; }

}

[XmlType("Resources")]
public class Resources {

    //Each prop can be extended to food being a Food object with expiry, etc
    [XmlElement("Food")]
    public int Food { get; set; } // 0 to cap
    [XmlElement("Happiness")]
    public int Happiness { get; set; } // 0 to 100
    [XmlElement("Energy")]
    public int Energy { get; set; } //0 to cap
    [XmlElement("ShipHp")]
    public int ShipHp { get; set; }// cap to 0
    [XmlElement("Garbage")]
    public int Garbage { get; set; } // 0 to cap
}

這是我的反序列化代碼：

   public class EventHandler : MonoBehaviour
{

    [XmlInclude(typeof(Event))]
    [XmlInclude(typeof(Resources))]
    [Serializable, XmlRoot("Events")]
    public class EventData
    {
        [XmlElement("Event")]
        public List<Event> Events { get; set; }

        public EventData()
        {
            List<Event> Events = new List<Event>();
        }
    }

    List<Event> Events = new List<Event>();
    public static EventHandler instance;

    // Use this for initialization, called on script enabling
    void Start()
    {

        var serializer = new XmlSerializer(typeof(EventData));
        try
        {
            string xml = File.ReadAllText("Assets/TextResources/Events.xml");
            xml = xml.Replace("\n", string.Empty);
            xml = xml.Replace("\r", string.Empty);
            xml = xml.Replace("\t", string.Empty);
            using (var stringReader = new StringReader(xml))
            {
                using (var reader = XmlReader.Create(stringReader))
                {
                    var result = (EventData)serializer.Deserialize(reader);
                    Events = result.Events;

                }
            }
        }
        catch(Exception ex)
        {
            Debug.Log(ex);
        }
    }
}

因此，從這段代碼中，我的事件對象中填充了Description ， EventType和EventId的值，但是Reward和Cost資源對象中卻沒有填充這些值，到目前為止，我不知所措。 為了獲得加分，我還努力尋找一種方法，以簡單地除去解析字符串后得到的所有無效空間。 （即Good更改為“ \\ n \\ r Good”）。

好。 因此，我找到了解決問題的方法，我對這方面都不是專家，因此，如果有任何更正經驗的人想要添加改進以改進代碼，我將很樂意進行更改。

首先，我的XML存在一個格式問題，要找到這個，我實際上序列化了一個事件對象列表，並使用生成的文本來找到解決方案，以下是修改后的文本：

<ArrayOfEvent xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Event>
    <Description>abc</Description>
    <Reward>
      <Food>0</Food>
      <Happiness>2</Happiness>
      <Energy>1</Energy>
      <ShipHp>3</ShipHp>
      <Garbage>4</Garbage>
    </Reward>
    <Cost>
      <Food>0</Food>
      <Happiness>2</Happiness>
      <Energy>1</Energy>
      <ShipHp>3</ShipHp>
      <Garbage>4</Garbage>
    </Cost>
    <EventId>1</EventId>
    <EventType>Good</EventType>
  </Event>
  <Event>
    <Description>def</Description>
    <Reward>
      <Food>0</Food>
      <Happiness>2</Happiness>
      <Energy>1</Energy>
      <ShipHp>3</ShipHp>
      <Garbage>4</Garbage>
    </Reward>
    <Cost>
      <Food>0</Food>
      <Happiness>2</Happiness>
      <Energy>1</Energy>
      <ShipHp>3</ShipHp>
      <Garbage>4</Garbage>
    </Cost>
    <EventId>2</EventId>
    <EventType>Good</EventType>
  </Event>
</ArrayOfEvent>

所以首先要注意的是，我序列化了事件對象列表，這些對象是<ArrayOfEvent>標記和生成的xml名稱空間屬性。 從那開始。 這也意味着我必須從EventData類更改為List<Event> ，這在任何方面都更加方便。 從Event和Resources類中，我將[Serializable, XmlRoot()]標記添加到了它們的類中。 要注意的另一件事是，我將EventType從字符串交換為枚舉，該枚舉的代碼也將在下面提供。這些修補程序還修復了我從xml純文本獲取到XmlReader的格式問題，我將共享完整的以下代碼供將來的讀者使用：

[Serializable, XmlRoot("Event")]
public class Event
{
    [XmlElement("Description")]
    public string Description { get; set; }

    [XmlElement("Reward")]
    public Resources Reward { get; set; }

    [XmlElement("Cost")]
    public Resources Cost { get; set; }

    [XmlElement("EventId")]
    public int EventId { get; set; }

    [XmlElement("EventType")]
    public EventType EventType { get; set; }
    [XmlIgnore]
    public string MarkUp { get; set; }
}


[Serializable, XmlRoot("Resources")]
public class Resources
{
    //Each prop can be extended to food being a Food object with expiry, etc
    [XmlElement("Food")]
    public int Food { get; set; } // 0 to cap
    [XmlElement("Happiness")]
    public int Happiness { get; set; } // 0 to 100
    [XmlElement("Energy")]
    public int Energy { get; set; } //0 to cap
    [XmlElement("ShipHp")]
    public int ShipHp { get; set; }// cap to 0
    [XmlElement("Garbage")]
    public int Garbage { get; set; } // 0 to cap
}

[XmlType("EventType")]
public enum EventType
{
    [XmlEnum("Good")]
    Good = 0,
    [XmlEnum("Bad")]
    Bad,
    [XmlEnum("Neutral")]
    Neutral
}


public class EventHandler : MonoBehaviour
{

    List<Event> Events = new List<Event>();

    // Use this for initialization, called on script enabling
    void Start()
    {
        try
        {
            var serializer = new XmlSerializer(typeof(List<Event>));

            string xml = File.ReadAllText("Assets/TextResources/Events.xml");
            xml = XDocument.Parse(xml).ToString(SaveOptions.DisableFormatting);

            using (var stringReader = new StringReader(xml))
            {
                using (var reader = XmlReader.Create(stringReader))
                {
                    var result = (List<Event>)serializer.Deserialize(reader);
                    Events = result;
                }
            }
        }
        catch (Exception ex)
        {
            Debug.Log(ex);
        }
    }
}

基本序列化方法

private void serializeList()
{
    XmlSerializer ser = new XmlSerializer(typeof(List<Event>));
    List<Event> list = new List<Event>();
    list.Add(new Event { EventId = 1, Description = "abc", EventType = EventType.Good, Cost = new Resources { Food = 0, Energy = 1, Happiness = 2, ShipHp = 3, Garbage = 4 }, Reward = new Resources { Food = 0, Energy = 1, Happiness = 2, ShipHp = 3, Garbage = 4 } });
    list.Add(new Event { EventId = 2, Description = "def", EventType = EventType.Good, Cost = new Resources { Food = 0, Energy = 1, Happiness = 2, ShipHp = 3, Garbage = 4 }, Reward = new Resources { Food = 0, Energy = 1, Happiness = 2, ShipHp = 3, Garbage = 4 } });
    list.Add(new Event { EventId = 3, Description = "ghi", EventType = EventType.Good, Cost = new Resources { Food = 0, Energy = 1, Happiness = 2, ShipHp = 3, Garbage = 4 }, Reward = new Resources { Food = 0, Energy = 1, Happiness = 2, ShipHp = 3, Garbage = 4 } });
    StreamWriter sw = new StreamWriter("Assets/TextResources/test.xml");
    ser.Serialize(sw, list);
    sw.Close();
}

Answer 2

您的XML無效。 您的第一個Resources標簽永遠不會關閉。
