C#实现接口xml序列化与反序列化

C#实现接口xml序列化与反序列化

 

C#中接口无法被xml序列化，提示不支持。百度和bing也搜不到，只好自己动手写了

原理上肯定支持，.Net自己的xml序列化有一个IXmlSerializable接口。

自行实现该接口，并取得类名，再进行自定义的序列化处理即可。

 

using System.Collections;

using System.Xml.Serialization;

using System;

using System.Xml;



[XmlRoot("SerInterface"), Serializable]

public class SerInterface<TInterface> : IXmlSerializable

{

    public TInterface Source { get { return (TInterface)mSource; } }

    string mTypeName;

    object mSource;





    public SerInterface()

    {



    }



    public SerInterface(object interfaceObj)

    {

        this.mSource = interfaceObj;

        mTypeName = mSource.GetType().FullName;

    }



    public System.Xml.Schema.XmlSchema GetSchema()

    {

        return null;

    }



    public void ReadXml(XmlReader reader)

    {

        var typeSer = new XmlSerializer(typeof(string));

        bool wasEmpty = reader.IsEmptyElement;

        reader.Read();



        if (wasEmpty)

            return;

        while (reader.NodeType != XmlNodeType.EndElement)

        {

            reader.ReadStartElement("Type");

            mTypeName = typeSer.Deserialize(reader) as string;



            reader.ReadEndElement();



            var sourceSer = new XmlSerializer(Type.GetType(mTypeName));

            reader.ReadStartElement("Object");

            mSource = sourceSer.Deserialize(reader);

            reader.ReadEndElement();

            reader.MoveToContent();

        }

        reader.ReadEndElement();

    }



    public void WriteXml(XmlWriter writer)

    {

        var typeSer = new XmlSerializer(typeof(string));

        var sourceSer = new XmlSerializer(mSource.GetType());



        writer.WriteStartElement("Type");

        typeSer.Serialize(writer, mTypeName);

        writer.WriteEndElement();

        writer.WriteStartElement("Object");

        sourceSer.Serialize(writer, mSource);

        writer.WriteEndElement();

    }

}

 

 

使用：

//把接口嵌套

IXXX tmp = new Class1();

var serInterface = new SerInterface<IXXX>(tmp);





//序列化

var xmlSer = new XmlSerializer(serInterface.GetType());

var writer = new MemoryStream();



xmlSer.Serialize(writer, serInterface);



StreamReader sr = new StreamReader(writer);

var serStr = Encoding.UTF8.GetString(writer.ToArray());



writer.Flush();

writer.Close();

sr.Close();





//反序列化

xmlSer = new XmlSerializer(typeof(SerInterface<IXXX>));

TextReader reader = new StringReader(serStr);

var deSer =  xmlSer.Deserialize(reader);



//原始数据

var sourceInterfaceData = (deSer as SerInterface<IXXX>).Source;
