how to get error by email in mvc4

Hi Surendra,

Application_Error event, can use to catching error either in log file or plain text file or store in db or email too.


Step-1 global.asax
void Application_Error(object sender, EventArgs e)
{
  var error = Server.GetLastError();
  if (error.Message != "Not Found")
   {
        // Send email here...
   }
}

Step-2 web.config
set customErrors="Off

Step-3

public class MvcApplication : System.Web.HttpApplication
{
  public static void RegisterGlobalFilters(GlobalFilterCollection filters)
  {
  filters.Add(new HandleErrorAttribute()); // Must Remove this line,
  }
...
}

Why Remove this line
By default (when a new project is generated), an MVC application has some logic in the Global.asax.cs file. This logic is used for mapping routes and registering filters. By default, it only registers one filter: a HandleErrorAttribute filter. When customErrors are on (or through remote requests when it is set to RemoteOnly), the HandleErrorAttribute tells MVC to look for an Error view and it never calls the Application_Error() method

To get the ApplicationError() method called for every unhandled exception, simple remove the line which registers the HandleErrorAttribute filter.
