如何在從具有工作“XmlInclude”屬性的基類繼承的類中包含“XmlInclude”？

Question

我在我的解決方案中有多個項目，我正在使用覆蓋任何自定義單個客戶端請求以保持代碼盡可能有條理。 在這個特定的覆蓋中，我試圖從序列化的基類繼承我將要做但我在嘗試序列化時遇到錯誤。

//In the Base project serialization works 100%
namespace Template
{
    //[XmlInclude(typeof(StaticText))]
    //[XmlInclude(typeof(BoundText))]
    //[XmlInclude(typeof(StaticImage))]
    //[XmlInclude(typeof(BoundImage))]
    //[XmlInclude(typeof(Font))]
    public class objType
    {
        public float X { get; set; }
        public float Y { get; set; }
        public float Height { get; set; }
        public float Width { get; set; }
    }

    public class ObjMain()
    {
        public string ObjName { get; set; }
        public List<objType> ObjTypeItems { get; set; }
    }

    public class DoWork() {
        using (System.IO.TextReader tr = new System.IO.StringReader(templateXML))
        {
            System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(ObjMain));
            bg = (ObjMain)serializer.Deserialize(tr);
        }
    }
}



/*

    <ObjName>Section 1</ObjName>
    <ObjTypeItems>
        <objType xsi:type="StaticText">

    public class CustomObjType : objType
    {

    }

    public class CustomObjMain()
    {
        public string CObjName { get; set; }
        public List<CustomObjType> CObjTypeItems { get; set; }

    public class DoWork() {
        using (System.IO.TextReader tr = new System.IO.StringReader(templateXML))
        {
            System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(CustomObjMain));//Error
            bg = (CustomObjMain)serializer.Deserialize(tr);
        }
    }

我的感覺是類屬性不是繼承基類。 但我也嘗試將屬性添加到從基類繼承的類中，但沒有運氣，錯誤繼續顯示在第一行的xml中，並添加了“xsi：type =”。

試試以下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication5
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            ObjMain objects = new ObjMain()
            {
                ObjName = "Main",
                objects = new List<ObjMain>() {
                    new objType1 { ObjName = "type 1" , X = 1.0F, Y = 2.0F, Height = 5F, Width = 10F},
                    new objType2 { ObjName = "type 2" , X = 1.5F, Y = 2.5F, Height = 5.5F, Width = 10.5F}
                }
            };

            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            XmlWriter writer = XmlWriter.Create(FILENAME, settings);
            XmlSerializer serializer = new XmlSerializer(typeof(ObjMain));
            serializer.Serialize(writer, objects);


        }
    }
    public class objType1 : ObjMain
    {
        public float X { get; set; }
        public float Y { get; set; }
        public float Height { get; set; }
        public float Width { get; set; }
    }
    public class objType2 : ObjMain
    {
        public float X { get; set; }
        public float Y { get; set; }
        public float Height { get; set; }
        public float Width { get; set; }
    }

    [XmlInclude(typeof(objType1))]
    [XmlInclude(typeof(objType2))]
    public class ObjMain
    {
        public string ObjName { get; set; }
        [XmlElement()]
        public List<ObjMain> objects { get; set; }
    }
}
