C# 通过WCF回调发送业务对象时发生超时

我有一个WCF服务，它是通过一个回调契约实现的，我正试图通过它发送一个业务对象。我用DataContract（）和DataMember（）属性装饰业务对象，它包含以下数量的属性：

• ints:3
• 字符串：4
• 元素：1
• 其他对象：5（也用DataContract（）和DataMember（）修饰）

每当我尝试通过回调发送此对象时，服务都会超时。我尝试过创建其他属性较少的对象以通过回调发送，如果只有一个属性，则可以让它通过，但如果我有多个属性，则服务会超时

我的配置有问题吗？我尝试了默认的wsDualHttpBinding和customBinding（如下所示）我已经尝试了maxBufferSize、maxBufferPoolSize和maxReceivedMessageSize的各种不同设置。我不想增加超时时间，因为我希望这个对象能够很快到达我的客户端。请有人帮帮我……如果我还有头发，我现在就把它拔出来了

我已将我的服务配置为：

将以下内容添加到web.config：

<system.diagnostics>
    <trace autoflush="true">
        <listeners>
        </listeners>
    </trace>
    <sources>
        <source name="System.ServiceModel"
                switchValue="Information, ActivityTracing"
                propagateActivity="true">

                <add name="sdt"
                     type="System.Diagnostics.XmlWriterTraceListener"
                     initializeData= "WcfDetailTrace.svclog" />
            </listeners>
        </source>
    </sources>
</system.diagnostics>

。这将为您提供有关发生了什么的大量信息。
其他对象有多大？例如，
XElement
的子树有多大？对象的图形最终可能会变得相当大，特别是在调用其他对象时

一种简单的调查方法可能是删除
[DataMember]
属性，除了其中一个字符串，然后一次重新引入一个属性，直到它断开。
我会看一看。
我创建了另一个测试对象，只考虑了一个属性，并成功地通过我的Web服务提交了它。我在这之后添加了另一个属性，它将不再通过…执行this产生了以下结果：尝试序列化参数时出错。InnerException消息为“Type”实用程序。不应为数据协定名称为“SubmittedJob:”的DAO.SubmittedJob。将任何静态未知的类型添加到已知类型列表中-例如，使用KnownTypeAttribute属性或将它们添加到传递给DataContractSerializer“”的已知类型列表。有关详细信息，请参阅InnerException。您可以使用KnownTypeAttribute（）为了列出从基类派生的所有类。我想我发现了问题…在Web服务中，我已将该方法定义为接受对象类型，并尝试发送SubmittedJob类型。我将Web服务更改为接受SubmittedJob，超时错误消失。感谢您的回答，但我已放弃Silverlight我几乎也不得不放弃一个，直到我发现这个…也许下次吧！
