我只能序列化 167 条记录.任何其他抛出 mscorlib.dll 中发生了类型为“System.StackOverf

老实说，我完全筋疲力尽了，我真的不知道该怎么办。我正在使用 Silverlight wcf 开发 Silverlight 应用程序。我的网络配置如下所示：

我在服务器和 Silverlight 项目之间共享程序集，以便可以在它们之间发送类。服务器生成 250 个对象。我可以在最多 167 的集合中发送它们。我可以从这 167 个对象中选择 VmNugget 的任何 250 个对象，这不是任何具体对象的问题。我的视图模型非常复杂，可以相互包含，一个可以是另一个的祖先。MY 类使用 [DataContract] 和 [DataMember] 属性进行修饰。您有什么提示如何在序列化期间检查该过程吗？我的网络服务是这样装饰的：

[ServiceKnownType(typeof(VmCulture))]
[ServiceKnownType(typeof(VmNugget))]
[ServiceKnownType(typeof(VmDesignedNugget))]
[ServiceKnownType(typeof(VmDesigner))]
[ServiceKnownType(typeof(OperationLog))]
[ServiceKnownType(typeof(OperationLog))]
[ServiceKnownType(typeof(VmFile))]
[ServiceKnownType(typeof(VmQuery))]
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class QueryService : BaseService

有趣的事情：

我已经从这样的属性中删除了所有构造函数：

private ObservableCollection<VmNugget> my;
[DataMember]
public ObservableCollection<VmNugget> My
get{
/* commented
if (this.my == null)
 this.my = new ObservableCollection<VmNugget>();
*/ 
return this.my;
}

我尝试将超过 167 个空对象放入返回的集合中，但我无法序列化它们并发送给客户端。这些对象应为空(未初始化(。

我正在使用带有行中的 OBservableCollection 属性的 VmQuery 类发送它。

谢谢。
