Result The results are stored in a List of type Result which is a class with four variables. List Result The method ExportToExcel currently returns string so that I can test if the list of results is null. Every single time it has come out as "No Data", therefore it is null. It perfectly prints out a table with the information in the Results page but does not have the information when i want to export it. ExportToExcel Results Why is my model not passing from view to method? At first I wanted to pass my model so that I can access the information in the List but now I am wondering if it would be better to s...

Ensure that a specific exception always results in a given HTTP response status code Requirement I have an ASP.Net MVC application that works with a number of different libraries. As with most libraries, various function calls may cause one of many different exceptions to be thrown. Currently, whenever any exception is thrown, then MVC application 'handles' them and returns an "internal server error" (code 500) back to the client (eg. web browser). This is fine for most cases, however, there is one specific exception type (in this case UnauthorizedAccessException ) that I would like to result in an "Unauthorized" (code 401) status being sent in the response, instead of the usual 500 error. UnauthorizedAccessException Current Attempt I did a fair bit of research and it looks like the bets way to 'catch' all exceptions and process them is by using the Application_Error method. So I tried the following implementation of Application_Error in the MvcApp...
