my error page is stored in views folder and in that shared folder. Please help me to show custom error page.
From given web.config file, seems that these lines triggering second exception while returning custom error page:
<customErrors mode="On" defaultRedirect="Error.cshtml" >
<error statusCode="404" redirect="~/Error.cshtml" />
</customErrors>
Since defaultRedirect attribute only accepts either absolute path to a HTML file or virtual/relative path to a controller action method, direct absolute path to a CSHTML file is inappropriate due to existence of Razor codes inside it which should be transformed to HTML by the server using an action method.
The issue can be solved by creating a controller class with a default action method like this (I assumed target error page exists inside /Views/Shared directory):
public class ErrorController : Controller
{
public ViewResult Index()
{
return View("Error");
}
}
Then, replace wrong path in defaultRedirect attribute with correct virtual path:
<customErrors mode="On" defaultRedirect="~/Error" >
<error statusCode="404" redirect="~/Error" />
</customErrors>
PS: You can implement custom error pages for status codes other than 404 by adding action methods that include Response.StatusCode = [HTML status code] inside ErrorController.
