计时器控制期间出现异常 [英] Exception Arises During Timer Control

问题描述

你好朋友

这次我正在做一个项目，在该项目中，我需要从数据库中获取与任何用户的时间，并检查数据库中的系统日期是否相同，并且系统时间是否也与一个通知相匹配，从而通知我需要在此致电此人时间.

朋友，我已经制作了所有d程序，唯一的问题是一段时间后，我说与数据库的连接断开了50秒，这使我无法确定连接状态的错误.

我有所有消息来源试图捕获此异常，但这种情况并未发生.
有人可以帮我解决这个问题吗?????????????并调试此异常，您需要收集更多信息.您可以广泛使用日志记录.我建议使用类 System.Diagnostics.EventLog记录大量详细信息，其中使用系统事件日志记录数据，使用事件查看器进行查找.

另请参阅我过去的解决方案:
将MsBuild OutPut即时发送到TextBox Windows应用程序中 [ ^ ]，
如何在文件夹下创建事件日志 [ ^ ].

解决方案

Hard to say what exactly could be wrong, but if you have problem to reproduce and debug this exception, you need to collect more information. You can use logging extensively. I would suggest using the class System.Diagnostics.EventLog to log a lot of detail using the system event log for the sink of data and Event Viewer for looking up.
