Good day to all! Trying to solve a problem. I use a method that handles all errors on the site (This method found on the blog of one man)
Global.asax
protected void Application_Error(object sender, EventArgs e)
{
HttpContext ctx = HttpContext.Current;
Exception ex = ctx.Server.GetLastError();
ctx.Response.Clear();
RequestContext rc = ((MvcHandler)ctx.CurrentHandler).RequestContext;
IController controller = new CategoryController();
var context = new ControllerContext(rc, (ControllerBase)controller);
var viewResult = new ViewResult();
var httpException = ex as HttpException;
if (httpException != null)
{
switch (httpException.GetHttpCode())
{
case 404:
viewResult.ViewName = "Error404";
break;
case 500:
viewResult.ViewName = "Error500";
break;
default:
viewResult.ViewName = "Error";
break;
}
}
else
{
viewResult.ViewName = "Error";
}
viewResult.ViewData.Model = new HandleErrorInfo(ex, context.RouteData.GetRequiredString("controller"), context.RouteData.GetRequiredString("action"));
viewResult.ExecuteResult(context);
ctx.Server.ClearError();
}
When I start Projects in the studio, causing the error. I get exception at that code:
RequestContext rc = ((MvcHandler)ctx.CurrentHandler).RequestContext;
Exception:
Unable to cast object of type '
System.Web.DefaultHttpHandler
' to type 'System.Web.Mvc.MvcHandler
'
Once I stop debugging (Shift + F5). This method works well and handles any errors. But at the start of project, causing the error. Looking for a solution to these topics, but this problem is not found. Help please.
[HandleError]
public class CategoryController : Controller
{
// some methods
}
Solved his problem by using code:
void Application_Error(object sender, EventArgs e)
{
Exception ex = Server.GetLastError();
if (ex is HttpException && ((HttpException)ex).GetHttpCode() == 404)
{
Response.Redirect("~/Error/404");
}
else
{
Response.Redirect("~/Error/Other");
}
Server.ClearError();
}
