防止应用程序事件日志中出现ASP.NET MVC2异常

自从升级到ASP.NET MVC2之后,我们注意到Windows应用程序事件日志中充满了以下条目:

Event code: 3005 
Event message: An unhandled exception has occurred. 
Event time: 11/4/2010 3:29:16 PM 
Event time (UTC): 11/4/2010 7:29:16 PM 
Event ID: 2039870297302976340236
Event sequence: 6422
Event occurrence: 864 
Event detail code: 0 

...
Exception information: 
Exception type: ArgumentException 
Exception message: The parameters dictionary contains a null entry for parameter 'someParam' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Index(System.String, Int32)' in 'SomeNameSpace.SomeController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.

请求不正确,因此出现此错误。很好,但是我希望在我的应用程序中处理这个问题,而不是允许它冒泡出事件日志。有什么建议吗?
