I'm following a tutorial on Exception Filter Attributes in ASP.NET MVC 5. The following is my code:
/Infrastructure/RangeExceptionAttribute.cs
using System;
using System.Web.Mvc;
namespace Filters.Infrastructure
{
public class RangeExceptionAttribute : FilterAttribute, IExceptionFilter
{
public void OnException(ExceptionContext filterContext)
{
if (!filterContext.ExceptionHandled && filterContext.Exception is ArgumentOutOfRangeException)
{
filterContext.Result = new RedirectResult("~/Content/RangeErrorPage.html");
filterContext.ExceptionHandled = true;
}
}
}
}
/Content/RangeErrorPage.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Range Error</title>
</head>
<body>
<h2>Sorry</h2>
<span>One of the arguments was out of the expected range.</span>
</body>
</html>
/Controllers/HomeController.cs
using System.Web.Mvc;
using Filters.Infrastructure;
using System;
using System.Web;
namespace Filters.Controllers
{
public class HomeController : Controller
{
[RangeException]
public string RangeTest(int id)
{
if (id > 100)
return String.Format("The id value is: {0}", id);
else
throw new ArgumentOutOfRangeException("id", id, "");
}
}
}
Now upon navigation to URL /Home/RangeTest/50, the expectation is user would be redirected to the /Content/RangeErrorPage.html page. However, Visual Studio debugger breaks and says ArgumentOutOfRangeException was unhandled by user code. What could be the issue here? Am I missing something?
