您可以解决FileNotFoundException吗?如果不应发生异常，则应解决问题而不是抑制问题.要处理已知的异常，可以使用以下代码.

Cant you resolve the FileNotFoundException instead? If the exception should not occur then rather resolve the issue than suppressing it. To handle a known exception you can use the following code.

if(Server.GetLastError().GetBaseException() is System.Web.HttpException)
{
     //You could check whether the 
     //Server.GetLastError().GetBaseException().Message contains the appropriate message
     Debug.WriteLine("Suppressed FileNotFoundException");
}else
//Log an unhandled exception
