纠结了两天的DataContractSerializer 反序列化xml的问题，在线等啊
xml格式Contract
string data =
"<Contract xmlns=\"http://tianka.com\">
<Title>合同版权</Title>

<Copyrights> //一个合同里面有多个版权实体
<Copyright ><WorksName>青色平原</WorksName></Copyright>
<Copyright ><WorksName>西游记</WorksName></Copyright>
</Copyrights>

</Contract>";

下面是DataContract契约类

//合同类
[DataContract(Namespace = "http://tianka.com")]
public class Contract
{
[DataMember]
public int Title{ get;set;}

private List<Copyright> m_copyrights = new List<Copyright>();
[DataMember]
public List<Copyright> Copyrights
{
get
{
return this.m_copyrights;
}
set
{
this.m_copyrights = value;
}
}
}

//版权类
[DataContract]
public class Copyright
{
[DataMember]
public string WorksName { get; set; }

}

问题:

//反序列化为对象
byte[] bytes = UnicodeEncoding.UTF8.GetBytes(data);
DataContractSerializer xml = new DataContractSerializer(typeof(Contract));
MemoryStream ms = new MemoryStream(bytes);
Contract c = (Contract)xml.ReadObject(ms);

序列化完之后c.Copyrights总是为null.请高手解答。

你的XML可能有问题，如果记得没错，集合类用DataContract是会多一层节点出来的。

你直接把你的类‘正序列化’之后，和你的XML对比一下就知道了

帮lz试了一把

C# code

class Program {    static void Main(string[] args) {        //var c = new Contract {        //    Title = "合同版权",        //    Copyrights = new List<Copyright> {         //        new Copyright{WorksName="worksname1"},        //        new Copyright{WorksName="worksname2"},        //        new Copyright{WorksName="worksname3"}        //    }        //};        //using (MemoryStream ms = new MemoryStream()) {        //    var xs = new XmlSerializer(typeof(Contract));        //    xs.Serialize(ms, c);        //    Console.WriteLine(Encoding.UTF8.GetString(ms.GetBuffer()));        //}        string data = "<Contract><Title>合同版权</Title><Copyrights><Copyright ><WorksName>青色平原</WorksName></Copyright><Copyright><WorksName>西游记</WorksName></Copyright></Copyrights></Contract>";        var xs = new XmlSerializer(typeof(Contract));        var c = xs.Deserialize(new StringReader(data)) as Contract;        Console.WriteLine(c.Copyrights.Count);        foreach(var each in c.Copyrights){            Console.WriteLine(each.WorksName);        }        Console.WriteLine("press any key to exit.");        Console.ReadLine();    }}[DataContract]public class Contract {    [DataMember]    public string Title { get; set; }    private List<Copyright> m_copyrights = new List<Copyright>();    [DataMember]    public List<Copyright> Copyrights {        get { return this.m_copyrights; }        set { this.m_copyrights = value; }    }}//版权类[DataContract]public class Copyright {    [DataMember]    public string WorksName { get; set; }}

1. 指定次序(默认C在T前面，而Copyrights在Title后面):
[DataMember(Order=1 
 )]
public List<Copyright> Copyrights

2. 指定名字：
[DataContract(Namespace = "http://tianka.com", Name = "Copyright")]
public class Copyright
