Custom Action Result Sample in MVC: Day 36

So far we have seen the following built-in action result types and the action helper methods that return them.

Action Result	Helper Method	Link
ContentResult	Content	Content Result: Day 9
RedirectResult	Redirect	Redirect Result: Day 10
ViewResult	View	View Result: Day 11
JavaScriptResult	JavaScript	JavaScript Result: Day 12
JsonResult	Json	JSON Result: Day 13
HttpStatusCodeResult HttpUnauthorizedResult HttpNotFoundResult	HttpNotFound	HttpNotFound Result: Day 14
FileResult FilePathResult		File File Result: Day 15

Now let's see the custom action result method step-by-step:

1. Create a MVC project from the "Empty" template.
   
   
2. Right-click on the project and select "Add" > "Class".
   
   
   
   
3. Name it "XMLResult".
   
   
   
   
4. Inherit the XMLResult class from ActionResult and override the "ExecuteResult" method.
   
   Create an object of "HttpResponseBase" class, that is a base class for classes that provides Http response information from an ASP.NET operations.
   
   
   • Set the content type to application/XML.
   • Create a parameterized constructor of the XMLResult class and pass a datatable as the parameter.
   • Assign a datatable objet to the local datatable object inside the constructor.
   • Create a dataset object inside the ExecuteResult method and add a datatable to that object.
   
   
   
   
5. Now add a controller. Right-click on "Controllers" then select "Add" >> "Controller".
   
   
   
   
6. Select "MVC 5 Controller – Empty" and press the "Add" button.
   
   
   
   
7. Name it as follows:
   
   
   
   
8. Create a datatable object and fill it with some values in the Index action result method.
   
   Return XMLResult with datatable.
   
   
   
   
9. Now run the project and you will see that our datatable is converted into XML using our custom action result.
