DataContractSerializer没有正确反序列化,缺少对象中方法的值

Question

我的SomeClass

[Serializable]
[DataContract(Namespace = "")]
public class SomeClass
{
    [DataMember]
    public string FirstName
    { 
        get; set;
    }

    [DataMember]
    public string LastName
    { 
        get; set;
    }

    [DataMember]
    private IDictionary<long, string> customValues;
    public IDictionary<long, string> CustomValues
    {
        get { return customValues; }
        set { customValues = value; }
    }
}

我的XML文件:

<?xml version="1.0" encoding="UTF-8"?>
 <SomeClass>
 <FirstName>John</FirstName>
 <LastName>Smith</LastName>
 <CustomValues>
    <Value1>One</Value1>
    <Value2>Two</Value2>
 </CustomValues >
 </SomeClass>

但我的问题是在课堂上,我只是在反序列化时得到了一些我方法的数据.

var xmlRoot = XElement.Load(new StreamReader(
                    filterContext.HttpContext.Request.InputStream,
                    filterContext.HttpContext.Request.ContentEncoding));
XmlDictionaryReader reader = XmlDictionaryReader.CreateDictionaryReader(xmlRoot.CreateReader());
 DataContractSerializer ser = new DataContractSerializer(typeof(SomeClass));
//Deserialize the data and read it from the instance.
SomeClass someClass = (SomeClass)ser.ReadObject(reader, true);

因此,当我检查"someClass"时,FirstName将具有值john,但LastName将为null.

神秘的是我如何获得一些数据,而不是课堂上的所有数据.因此,反序列化时,DataContractSerializer不会从xml中提取所有数据.

难道我做错了什么.

任何帮助表示赞赏.提前致谢.

如果有人遇到同样的问题,或者任何人有解决方案,请告诉我

好吧,我在玩了很多之后找到了自己的回答......它必须是一个alpahbetical顺序.所以如果上课了

[Serializable]
[DataContract(Namespace = "")]    
public class SomeClass
{
    [DataMember]
    public string FirstName
    { 
        get; set;
    }

    [DataMember]
    public string LastName
    { 
        get; set;
    }

    [DataMember]
    private IDictionary<long, string> customValues;
    public IDictionary<long, string> CustomValues
    {
        get { return customValues; }
        set { customValues = value; }
    }
}

那么xml应该按字母顺序定义.

<?xml version="1.0" encoding="UTF-8"?>
 <SomeClass>
 <CustomValues>
    <Value1>One</Value1>
    <Value2>Two</Value2>
 </CustomValues >
 <FirstName>John</FirstName>
 <LastName>Smith</LastName>
 </SomeClass>

为什么h ...它必须按字母顺序排列？

这就是Order属性的用途; 如果你无法控制你反序列化的XML,那就是我所知道的唯一解决方法.

在你的第一个例子中

[Serializable]
[DataContract(Namespace = "")]
public class SomeClass
{
    [DataMember(Order = 0)]
    public string FirstName
    { 
        get; set;
    }

    [DataMember(Order = 1)]
    public string LastName
    { 
        get; set;
    }

    [DataMember(Order = 2)]
    private IDictionary customValues;
    public IDictionary CustomValues
    {
        get { return customValues; }
        set { customValues = value; }
    }
}
