/// </summary>
/// <param name="filterContext"></param>
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
//1. action

}異常フィルタ:HandleErrorAttribute
public override void OnException(ExceptionContext filterContext)
{
//1.
Exception ex= filterContext.Exception;
//2.
//2.1 ...
//3. mvc ， ，
filterContext.ExceptionHandled = true;
base.OnException(filterContext);
}構成エラー・ページ:
1 <customErrors mode="On" defaultRedirect="Error">
2 <error statusCode="404" redirect="~/ErrorMgr/P404" />
3 <error statusCode="500" redirect="~/ErrorMgr/P500"/>
4 </customErrors>
