创建一个可序列化的类 - 复杂对象

我需要将数据序列化为XML,但我在解决如何执行此操作时遇到了麻烦。 (在Visual Studio中)

我需要在结构下面创建这种类型的XML。但是Object FormType包含IList,它不会序列化。

<?xml version="1.0" encoding="utf-16"?>
<VersionXml xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ImportId>1</ImportId>
<Environment>SIT</Environment>
<DateExported>12/2/2014</DateExported>
<FormType>
    <Id>4000</Id>
    <FormTypeVersion>
        <DisplayName>display name here</DisplayName>
        <FormNumber>12345<FormNumber>
        <Name>12345-abc<Name>
        <CompanyId>1</CompanyId>
        <Active>1<Active>
        <RevisionHistoryNumber>2<RevisionHistoryNumber>
    <FormTypeVersion>
    <FormTypeVersion>
        <DisplayName>display name here</DisplayName>
        <FormNumber>12345<FormNumber>
        <Name>12345-abc<Name>
        <CompanyId>1</CompanyId>
        <Active>1<Active>
        <RevisionHistoryNumber>3<RevisionHistoryNumber>
    <FormTypeVersion>
</FormType>
<FormType>
    <Id>4001</Id>
    <FormTypeVersion>
        <DisplayName>another one here</DisplayName>
        <FormNumber>456<FormNumber>
        <Name>456-bcd<Name>
        <CompanyId>1</CompanyId>
        <Active>1<Active>
        <RevisionHistoryNumber>3<RevisionHistoryNumber>
    <FormTypeVersion>
    <FormTypeVersion>
        <DisplayName>another one here</DisplayName>
        <FormNumber>456<FormNumber>
        <Name>456-bcd<Name>
        <CompanyId>1</CompanyId>
        <Active>1<Active>
        <RevisionHistoryNumber>1<RevisionHistoryNumber>
    <FormTypeVersion>
</FormType>
</VersionXml>

这是我尝试创建的类,但FormType不会序列化并产生反射器错误

[Serializable]
    public class FormXml
    {
        public string ImportID  { get; set; }
        public string Environment { get; set; }
        public string DateExported { get; set; }  
        public IEnumerable<FormType> FormType { get; set; }
    }

这是收到的错误:

Cannot serialize member FormXml.FormType of type System.Collections.Generic.IEnumerable`1..... because it is an interface.

我无法将IList更改为List - 那么还有另一种方法吗?

这是thr FormType.cs

[Serializable]
    public class FormType : Entity
    {
        public virtual ProductCode Product { get; set; }

        public virtual String DisplayName { get; set; }

        public virtual String FormNumber { get; set; }

        public virtual String Name { get; set; }

        public virtual Boolean Active { get; set; }

        private IList<FormTypeVersion> _versions = new List<FormTypeVersion>();

        public virtual IList<FormTypeVersion> Versions
        {
            get { return _versions; }
            set { _versions = value; }
        }
    }

2 个答案:

答案 0 :(得分:0)

实现此目的使用可序列化类型而不是IEnumerable<FormType>,可能是List<FormType>

[edit]当然,FormType也必须实现ISerializable。

答案 1 :(得分:0)

因此,对于我所提供的资源,我带来了示例

<强>富

[Serializable]
[XmlRoot("Foo")]
public class Foo
{
    [XmlArray("BarList"), XmlArrayItem(typeof(Bar), ElementName = "Bar")]
    public List<Bar> BarList { get; set; }
}

<强>酒吧

[Serializable]
public class Bar
{
    public string Property1 { get; set; }
    public string Property2 { get; set; }
}

要测试的代码

Foo f = new Foo();
f.BarList = new List<Bar>();
f.BarList.Add(new Bar() { Property1 = "s", Property2 = "2" });
f.BarList.Add(new Bar() { Property1 = "s", Property2 = "2" });

FileStream fs = new FileStream("c:\\test.xml", FileMode.OpenOrCreate);
System.Xml.Serialization.XmlSerializer s = new System.Xml.Serialization.XmlSerializer(typeof(Foo));
s.Serialize(fs, f);

<强>输出

<?xml version="1.0" ?> 
<Foo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <BarList>
        <Bar>
            <Property1>s</Property1> 
            <Property2>2</Property2> 
        </Bar>
        <Bar>
            <Property1>s</Property1> 
            <Property2>2</Property2> 
        </Bar>
    </BarList>
</Foo>

这展示了如何使用自定义类列表序列化xml。

你也可以参考:

修改 你也可以:

[Serializable]
[XmlRoot]
public class FormXml
{
    public string ImportID  { get; set; }
    public string Environment { get; set; }
    public string DateExported { get; set; }  
    [XmlIgnore]
    public IEnumerable<FormType> FormType { get; set; }
    [XmlElement, Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]
    public List<FormType> Foo { get { return FormType.ToList() } set { FormType = value; } }
}
