C# 序列化不'；I don’我不接受我的赞扬，为什么？

我遇到了一个序列化问题。我的Silverlight应用程序不希望businessobject中有我的属性，也不知道该怎么办。之前，我通过设置KnownTypeAttribute解决了这个问题，如下面的示例所示，但在本例中，它不起作用

我曾经这样解决它：

[DataContract(Name = "baseClass")]
public class baseClass { }

[DataContract(Name = "busObj1")]
public class busObj1 : baseClass { }

[DataContract(Name = "busObj2")]
[KnownType(typeof(busObj1))]
public class busObj2 : baseClass
{
    public busObj1 myObj { get; set; }
}

[DataContract(Name = "baseClass")]
public class baseClass { }

[DataContract(Name = "busObj1")]
public class busObj1 : baseClass { }

[DataContract(Name = "busObj2")]
[KnownType(typeof(busObj1))]
public class busObj2 : baseClass
{
    public busObj1 myObj { get; set; }
}

// This is the class that I want to send via WCF and that cannot be serialized
// because the serializer doesn't expect busObj1.
[DataContract(Name = "busObj3")]
public class busObj3 : busObj2 { }

我所知道的唯一区别是我的结构略有不同，如下所示：

[DataContract(Name = "baseClass")]
public class baseClass { }

[DataContract(Name = "busObj1")]
public class busObj1 : baseClass { }

[DataContract(Name = "busObj2")]
[KnownType(typeof(busObj1))]
public class busObj2 : baseClass
{
    public busObj1 myObj { get; set; }
}

[DataContract(Name = "baseClass")]
public class baseClass { }

[DataContract(Name = "busObj1")]
public class busObj1 : baseClass { }

[DataContract(Name = "busObj2")]
[KnownType(typeof(busObj1))]
public class busObj2 : baseClass
{
    public busObj1 myObj { get; set; }
}

// This is the class that I want to send via WCF and that cannot be serialized
// because the serializer doesn't expect busObj1.
[DataContract(Name = "busObj3")]
public class busObj3 : busObj2 { }

我非常感谢任何可能出错的想法

关于，Clas

您需要将已知类型属性放在基本对象上：

[DataContract(Name = "baseClass")]
[KnownType(typeof(busObj1))]
[KnownType(typeof(busObj2))]
[KnownType(typeof(busObj3))]
[KnownType(typeof(busObj4))]
public class baseClass { }

[DataContract(Name = "busObj1")]
public class busObj1 : baseClass { }

[DataContract(Name = "busObj2")]
public class busObj2 : baseClass { }

[DataContract(Name = "busObj3")]
public class busObj3 : busObj1
{
    public busObj2 myObj { get; set; }
}

[DataContract(Name = "busObj4")]
public class busObj4 : busObj3 { }

或者，如果您不想用这些属性污染域模型，您也可以。
