C# 无法让全局errorhandler处理我的自托管wcf服务

你好，我已经试着让Ierrorhandler工作了好几个小时了，我被卡住了：） 我从这本指南中得到了最多的结果

但是我不能让它与我的操作/功能一起工作

好的，如果我在里面放一些控制台，writeLine

公共类GlobalExceptionHandlerBehavior属性：属性，IServiceBehavior 当我启动程序时，我看到它们运行的函数。但是我无法在指南中找到使用我的函数抛出异常并让我的IErrorhandler捕获该异常的示例

我在其他函数中尝试了一些异常，但我的IErrorhandler没有发生任何变化

但是有一个异常被捕获了，我发现到目前为止，当我在Wcftestclient中添加服务，然后停止调试并删除IService.cs中的[OperationContract]，然后重新启动并尝试运行函数而不刷新时，该异常会被IErrorhandler捕获

所以我这里的问题是为什么我不能捕获函数中的异常？ 非常感谢你的回答。

c（：

FaultContractAttribute是否足以满足您的要求？ 看看msdn文档中的示例。 它听起来与您正在尝试做的事情相似，比定制服务行为复杂度更低

---

当跨进程/机器使用WCF时，FaultContracts相当于异常，因为使用者不一定是.net客户端。

hmm观看此站点[链接]我非常仔细地看到了我安装了带.net 4.0的windows xp的要求。现在运行windows update时大拇指交叉。有人知道这方面的情况吗？您使用哪些平台提供wcf服务？
