WCF：服务器端错误处理。最好的锻炼 [英] WCF: server-side error handling. best practice

问题描述

我写的WCF服务，并希望保持它的活动日志：跟踪，警告和错误消息。非常直接的方法是包装内的所有合约服务code的try / catch 部分和抓部分重新抛出服务合同错误异常。

I write WCF service and want to keep it's activity log: trace, warnings and error messages. The very straight-forward approach is to wrap all contract service code inside try/catch sections and write error messages from catch part rethrowing service contract error exceptions.

我想这将是很好，如果只安排一份code点到捕获所有未捕获的异常，而不是几十的try / catch 部分。这将是同样从该点写入合同法参数，提供详细的错误信息很有用。

I suppose it would be nice if there would be one code-point to catch all uncaught exceptions instead of dozens try/catch sections. It would be also useful to write contract method parameters from that point to provide detailed error information.

与WCF是否有可能？

Is it possible with WCF?

什么是组织错误处理内部WCF服务的最佳做法？

感谢你在前进！

推荐答案

看一看的 IErrorHandler 接口

它允许实施者控制故障信息返回给调用者，并根据需要执行自定义错误处理，如登录

It allows an implementer to control the fault message returned to the caller and optionally perform custom error processing such as logging

您可以实现您的服务行为（见 IServiceBehavior接口接口），你的处理程序添加到 ChannelDispatcher 错误处理程序。

You can implement your service behavior (see IServiceBehavior interface) and add your handler to ChannelDispatcher error handlers.

请参阅 WCF异常处理IErrorHandler 了解更多的细节。
