Xml 序列化基础 class 属性

Question

我正在使用 XmlSerializer class 序列化 Derived class "MyContext"，它继承了基础 Class "BaseClass"。基本 class 属性 "attr1"、"attr2" 不存在于序列化 XML output.I 中需要这些属性在上下文 class 和嵌套 class 在上下文 class 中。请帮助这里缺少什么。

namespace MyConsoleApplication
{
    [System.Xml.Serialization.XmlIncludeAttribute(typeof(MyContextType))]
    [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.6.1055.0")]
    [System.SerializableAttribute()]
    [System.Diagnostics.DebuggerStepThroughAttribute()]
    [System.ComponentModel.DesignerCategoryAttribute("code")]
    public partial class BaseType
    {
     private MyEnumType attr1Field;
     private MyEnumType attr2Field;

     [System.Xml.Serialization.XmlAttributeAttribute()]
     public MyEnumType Attr1
        {
            get
            {
                return this.attr1Field;
            }
            set
            {
                this.attr1Field= value;
            }
        }

     [System.Xml.Serialization.XmlAttributeAttribute()]    
     public MyEnumType Attr2
        {
            get
            {
                return this.attr2Field;
            }
            set
            {
                this.attr2Field= value;
            }
        }
    }


     [System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.6.1055.0")]
     [System.SerializableAttribute()]
     [System.Diagnostics.DebuggerStepThroughAttribute()]
     [System.ComponentModel.DesignerCategoryAttribute("code")]
     [System.Xml.Serialization.XmlRootAttribute("Context", Namespace = "", IsNullable = false)]
     public partial class MyContextType : BaseType
     {
         private string element1Field;

         private string element2Field;

         [System.Xml.Serialization.XmlElementAttribute(Order = 0)]
         public string Element1
         {
             get
             {
                 return this.element1Field;
             }
             set
             {
                 this.element1Field = value;
             }
         }
         [System.Xml.Serialization.XmlElementAttribute(Order = 1)]
         public string Element2
         {
             get
             {
                 return this.element2Field;
             }
             set
             {
                 this.element2Field = value;
             }
         }
     }

     public enum MyEnumType
     {

         /// <remarks/>
         False,

         /// <remarks/>
         True,
     }
}

我的序列化程序代码：

var mydoc = new XmlDocument();
var context = new MyContextType() { Element1 = "Car", Element2 = "Bike", Attr1 = "id1", Attr2 = "id2" };  

using (MemoryStream stream = new MemoryStream())
    {
        XmlSerializer s = new XmlSerializer(typeof(MyContextType));
        s.Serialize(XmlWriter.Create(stream), context);
        stream.Flush();
        stream.Seek(0, SeekOrigin.Begin);
        mydoc.Load(stream);
    }

输出Xml：

<MyContext>
    <Element1>Happy</Element1>
    <Element2>10</Element2>
</MyContext>

但我希望输出为

<MyContext attr1 = "False" attr2="False">
        <Element1>Happy</Element1>
        <Element2>10</Element2>
</MyContext>

Answer 1

解决方案是将 "Attr1Specified" 值指定为 true。这是答案。

 var context = new MyContextType() { Element1 = "Car", Element2 = "Bike", Attr1 = MyEnumType.False, Attr1Specified = true, Attr2 = MyEnumType.False, Attr2Specified = true };
