Question

我正在序列化的类：

public class StyleProperties
{
    [XmlAttribute]
    public string Name;
    [XmlAttribute]
    public string Description;
    [XmlAttribute]
    public StyleType Type;

    public ShapeStyleProperties ShapeStyle;
    public TextStyleProperties TextStyle;
}

负责序列化数据的部分：

XmlSerializer serializer = new XmlSerializer(typeof(StyleProperties));

PPT.Presentation pres = Globals.ThisAddIn.Application.ActivePresentation;
CustomXMLParts parts = pres.CustomXMLParts;

//var serializer = new DataContractSerializer(typeof(MyCustomData));
using (var stream = new MemoryStream())
{
    serializer.Serialize(stream, styleProperties);
    stream.Seek(0, SeekOrigin.Begin);

    var sr = new StreamReader(stream);
    var myStr = sr.ReadToEnd();
    Console.WriteLine(myStr);

    parts.Add(myStr);

}

负责反序列化的部分：

    public static T ReturnObjectFromXML<T>(CustomXMLPart customXMLPart)
    {

        using (XmlReader reader = XmlReader.Create(new StringReader(customXMLPart.XML)))
        {
            DataContractSerializer formatter0 =
                new DataContractSerializer(typeof(T));

            return (T)formatter0.ReadObject(reader);
        }        

   }

当然在行

中发生错误

return (T)formatter0.ReadObject(reader);

我得到的错误：

第1行位置出错23.期待元素'StyleProperties'来自命名空间'http://schemas.datacontract.org/2004/07/PPT_Styles_Tool'.. 遇到名为'StyleProperties'的'元素'，命名空间''。

所以从我看来没有命名空间：'http://schemas.datacontract.org/2004/07/PPT_Styles_Tool'但是我该如何修复呢？我是处理XML文档的新手，特别是将XML数据序列化/反序列化到对象

Answer 1

使用[XmlElement]属性：

[XmlElement(ElementName = "StyleProperties", Namespace="http://schemas.datacontract.org/2004/07/PPT_Styles_Tool")]
public class StyleProperties
{
//...

此外，如果使用XmlSerializer进行序列化，则应使用XmlSerializer进行反序列化。不是DataContractSerializer。

反序列化XML时出错
