这是需要序列化的类。
[DataContract]
public class Fullresponse
{
[DataMember(Order=0)]
public string success { get; set; }
[DataMember]
public string participants { get; set; }
[DataMember]
public string term { get; set; }
[DataMember]
public categoryCollection categories { get; set; }
[DataMember]
public string total { get; set; }
}
这是categoryCollection Class
[DataContract]
public class categoryCollection
{
[DataMember]
public Results online { get; set; }
[DataMember]
public Results offline { get; set; }
}
这是结果类
public class Results
{
public string categoryName { get; set; }
public List<Node> results { get; set; }
}
我想从WCF服务到我的客户端应用程序获取Fullresponse类对象。 我怎样才能做到这一点。从这段代码中可以看出错误。当我从Fullresponse类中删除categoryCollection对象时，它可以正常工作。
这是我的服务web.config

请帮我解决这个问题。

您还需要将DataContract添加到Results课程。
DataContractSerializer是一个选择性序列化程序，意思是它只序列化你告诉序列化程序序列化的内容。由于您没有使用Results属性标记DataContract类，因此不会将其序列化。
所有.NET Framework原始类型（例如Byte, SByte, Int16, Int32, Int64, UInt16, UInt32, UInt64, Single, Double, Boolean, Char, Decimal, Object, and String）都可以序列化而无需其他准备工作，并被视为具有默认数据协定。
有关DataContractSerializer支持的类型的详细信息，请阅读msdn
[DataContract]
public class Results
{
[DataMember]
public string categoryName { get; set; }
[DataMember]
public List<Object> results { get; set; }
}

我解决了这个问题如下。
[KnownType(typeof(Contact)), KnownType(typeof(Apps)), KnownType(typeof(Person))]
[DataContract]
public abstract class Node
{
[DataMember]
public string title { get; set; }
[DataMember]
public string name { get; set; }
[DataMember]
public string url { get; set; }
[DataMember]
public string description { get; set; }
[DataMember]
public List<Action> actions { get; set; }
public virtual void AddComment()
{
}
public virtual void AddContact()
{
}
}
添加KnownType()
