使用序列化从XML文件读入C#类

Question

我有以下XML文件,我试图使用DE-serialization读入c#中的类:

<?xml version="1.0"?>
    <PropertiesMapping>
        <Property>
            <WEB_Class>InfoRequest</WEB_Class>
            <COM_Class>CInfoReq</COM_Class>
            <Mappings>
                <Map>
                    <WEB_Property>theId</WEB_Property>
                    <COM_Property>TheID</COM_Property>
                </Map>
                <Map>
                    <WEB_Property>theName</WEB_Property>
                    <COM_Property>NewName</COM_Property>
                </Map>
            </Mappings>
        </Property>
    </PropertiesMapping>

以下是我正在使用的代码,虽然它没有错误地执行,但没有数据被读入类PropertiesMapping,我在哪里错了？

PropertiesMapping pm = null;

        try
        {
            System.IO.StreamReader str = new System.IO.StreamReader(@"PropertyMapping.xml");
            System.Xml.Serialization.XmlSerializer xSerializer = new System.Xml.Serialization.XmlSerializer(typeof(PropertiesMapping));
            pm = (PropertiesMapping)xSerializer.Deserialize(str);
            str.Close();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }


[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "")]
    [System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
    public class PropertiesMapping
    {
        private string m_WEB_Class = "";
        private string m_COM_Class = "";

        private List<IndividualProperties> m_EachProperty = null;

        public string WEB_Class
        {
            get
            {
                return m_WEB_Class;
            }
            set
            {
                m_WEB_Class = value;
            }
        }

        public string COM_Class
        {
            get
            {
                return m_COM_Class;
            }
            set
            {
                m_COM_Class = value;
            }
        }

        public IndividualProperties GetIndividualProperties(int iIndex)
        {
            return m_EachProperty[iIndex];
        }

        public void SetIndividualProperties(IndividualProperties theProp)
        {
            m_EachProperty.Add(theProp);
        }
    }



public class IndividualProperties
    {
        private string m_WEB_PropertyField;

        private string m_COM_PropertyField;

        public string WEB_Property
        {
            get
            {
                return this.m_WEB_PropertyField;
            }
            set
            {
                this.m_WEB_PropertyField = value;
            }
        }

        public string COM_Property
        {
            get
            {
                return this.m_COM_PropertyField;
            }
            set
            {
                this.m_COM_PropertyField = value;
            }
        }
    }

您可以使用它XmlElementAttribute来简化您的C#命名.

指示当XmlSerializer序列化或反序列化包含它的对象时,公共字段或属性表示XML元素.

您将需要使用XmlArrayItemAttribute的Mappings元素.

表示一个属性,指定XmlSerializer可以放置在序列化数组中的派生类型.

类别:

[XmlType("PropertiesMapping")]
public class PropertyMapping
{
    public PropertyMapping()
    {
        Properties = new List<Property>();
    }

    [XmlElement("Property")]
    public List<Property> Properties { get; set; }
}

public class Property
{
    public Property()
    {
        Mappings = new List<Mapping>();
    }

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

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

    [XmlArray("Mappings")]
    [XmlArrayItem("Map")]
    public List<Mapping> Mappings { get; set; }
}

[XmlType("Map")]
public class Mapping
{
    [XmlElement("WEB_Property")]
    public string WebProperty { get; set; }

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

演示:

PropertyMapping result;

var serializer = new XmlSerializer(typeof(PropertyMapping));

using(var stream = new StringReader(data))
using(var reader = XmlReader.Create(stream))
{
    result = (PropertyMapping) serializer.Deserialize(reader);
}
