序列化代码示例中的无限循环

从这里查看以下代码。
它是关于在wcf中序列化时在数据提取（对象模型，对象图，域模型）中保留循环引用。

class ReferencePreservingDataContractSerializerOperationBehavior :DataContractSerializerOperationBehavior { public ReferencePreservingDataContractSerializerOperationBehavior( OperationDescription operationDescription) : base(operationDescription) { } public override XmlObjectSerializer CreateSerializer( Type type, string name, string ns, IList knownTypes) { return CreateDataContractSerializer(type, name, ns, knownTypes); } private static XmlObjectSerializer CreateDataContractSerializer( Type type, string name, string ns, IList knownTypes) { return CreateDataContractSerializer(type, name, ns, knownTypes); } public override XmlObjectSerializer CreateSerializer( Type type, XmlDictionaryString name, XmlDictionaryString ns, IList knownTypes) { return new DataContractSerializer(type, name, ns, knownTypes, 0x7FFF /*maxItemsInObjectGraph*/, false/*ignoreExtensionDataObject*/, true/*preserveObjectReferences*/, null/*dataContractSurrogate*/); } } 

不是CreateDataContractSerializer生成无限循环（stackoverflow） – 因此也是前面的CreateSerializer方法？

 private static XmlObjectSerializer CreateDataContractSerializer( Type type, string name, string ns, IList knownTypes) { return CreateDataContractSerializer(type, name, ns, knownTypes); } 

现在也许这些方法没有被使用？ 我在这里想念的是什么？

确实如此。 它工作的事实表明当前只调用了最后一个重载。 由于涉及不同的参数，也许最好丢失静态方法（这没有帮助）：

 public override XmlObjectSerializer CreateSerializer( Type type, string name, string ns, IList knownTypes) { return new DataContractSerializer(type, name, ns, knownTypes, 0x7FFF /*maxItemsInObjectGraph*/, false/*ignoreExtensionDataObject*/, true/*preserveObjectReferences*/, null/*dataContractSurrogate*/); } public override XmlObjectSerializer CreateSerializer( Type type, XmlDictionaryString name, XmlDictionaryString ns, IList knownTypes) { return new DataContractSerializer(type, name, ns, knownTypes, 0x7FFF /*maxItemsInObjectGraph*/, false/*ignoreExtensionDataObject*/, true/*preserveObjectReferences*/, null/*dataContractSurrogate*/); }
