.net wcf serialization error-handling

.net 如何在WCF中拦截序列化期间发生的异常？,.net,wcf,serialization,error-handling,.net,Wcf,Serialization,Error Handling,我有一个合法的数据对象，具有所有数据契约/数据成员属性。由于某些原因，WCF服务在操作完成并将结果作为返回值传递后崩溃。我相信这与WCF无法正确序列化该结果有关。测试客户端没有说任何特定的内容： The underlying connection was closed: The connection was closed unexpectedly. Server stack trace: at System.ServiceModel.Channels.HttpChannelUtil

我有一个合法的数据对象，具有所有数据契约/数据成员属性。由于某些原因，WCF服务在操作完成并将结果作为返回值传递后崩溃。我相信这与WCF无法正确序列化该结果有关。测试客户端没有说任何特定的内容：

The underlying connection was closed: The connection was closed unexpectedly.

我使用定制的服务主机工厂来控制创建服务实例

我知道我可以设置跟踪侦听器并检查日志，但这很麻烦。因此，我宁愿在发生时在服务器上显式地处理它

因此，我如何以编程方式截获该异常并返回适当的错误消息
