【问题描述】:
我使用 XmlSerializer 类来序列化继承基类“BaseClass”的派生类“MyContext”。序列化的 XML 输出中不存在基类属性“attr1”、“attr2”。我需要 Context 类和 Context 类中的嵌套类中的这些属性。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>
【问题讨论】:
-
XmlSerializer只会序列化公共类和成员。因为它是您的MyContext类,所以根本无法序列化。你能提供一个complete example你的问题吗? -
您的代码无法编译,并且您的类和属性未公开。一旦我对这些问题进行了合理的修复,我就无法重现您的问题。见dotnetfiddle.net/ueui7z
-
dbc:按要求更新了代码示例。请检查并告诉我
-
XmlAttributeAttribute没有Order属性,因此代码无法编译。如果我解决了这个问题,我仍然无法重现该问题,请参阅dotnetfiddle.net/CWQZ1Y。请注意,您将Attr1标记为[XmlElementAttribute]而不是[XmlAttributeAttribute],因此Attr1显示为元素而不是属性。Attr2虽然显示为属性。 -
我已经修复了编译器错误并更新了我的帖子。实际上,我通过在 MyContext 对象中指定“Attr1Specified”值来填充属性,如下所示。 var context = new MyContextType() { Element1 = "Car", Element2 = "Bike", Attr1 = "id1", Attr1Specified = true, Attr2 = "id2", Attr2Specified = true };
