Question

How can I send to action of controller different values for same field? Which input parameters should I define in action? And how can I show url with different values of identical fields in querystring? I want to get such url: site.com/directory?metro=2&metro=3
Thanks!

Here’s an example of how this would be done in the case of checkboxes. Note that you wouldn’t see the same querystring parameter repeated in the case of a GET request. Instead you would see “?metros=1,3” if checkboxes 1 and 3 were checked.

HTML

<form action="http://site.com/directory" method="get">
    <input type='checkbox' name='metros' value='1' />
    <input type='checkbox' name='metros' value='2' />
    <input type='checkbox' name='metros' value='3' />
</form>

Controller

public class DirectoryController : Controller {
    public ActionResult Index(IEnumerable<int> metros) {
        foreach (var metro in metros) {
            // do something
        }

        return View();
    }
}
