推荐答案

为什么不使用一种可用的日志记录框架，我优先选择LoggingApplicationBlock，它将提供现成的大多数日志记录功能您的应用程序需求.将其与带有日志处理程序的ExceptionHandling应用程序块集成在一起，将使您可以将异常详细信息放在同一日志文件中.

Why not use one of the logging frameworks available, I preference is LoggingApplicationBlock, that will provide out of the box most of the logging features your application need. Integrating it with ExceptionHandling applicaiton block with log handler will allow you to put exception details in the same log file.
