what is the correct way to pass a range of values using "routing table" url format

Question

I am learning ASP.NET MVC and it is easy to pass a single value to a view, using the following url format:

controller/view/id

and in the controller's code, I can simply define the integer id parameter as below:

ActionResult View(int? id)
{
}

but what is the accepted programming pattern (in ASP.NET MVC) to pass a range of values

controller/view/id1-id2

and how would the View method (in codebehind) would look like?

Answer 1

Firstly it's

controller/action/some-url-segment

Views are but the presentation logic that an action method with a view result returns, typically passing the view a model.

Secondly: There are no code-bind files for ASP.NET MVC Views, this is not web forms.

A possible route on the server side may be defined as follows:

url: "{controller}/{action}/page-{pagenum}"

And this would catch any url such as /admin/getuserlist/page-5

And an action method would receive those url segment params too.

ActionResult GetUserList(int pagenum)

The above gets ActionMethod parameter values from URL segments defined in the route.

You could also pass such values via query string:

/Admin/getuserlist?page=3&pagesize=45

You do not need to modify routes when using query string to pass values.

and a route such as url: {controller}/{action}/

Would happily pass that request to:

ActionResult GetUserList(int page, int pagesize)

Answer 2

/Controller/Index?var1=1&var2=2&var3=3

ActionResult Index(int? var1, int? var2, int? var3)
{
    Return Content(
        String.Format("You entered: {0}, {1}, {2}", var1, var2, var3));
}

Result:

You entered: 1, 2, 3

/Controller/Index?values=1&values=2&values=3

ActionResult Index(IEnumerable<int> values)
{
    Return Content(
        String.Format("You entered: {0}, {1}, {2}", values[0], values[1], values[2]));
}

Result:

You entered: 1, 2, 3

I don't have any experience with code-behind, sorry. I'm curious, why do you use it?
