Action with a string array as parameter

Question

I want to call an action with something similar to this uri:

http://server/controller/action/?columns=firstname&columns=lastname&columns=age

and use it like this:

public ActionResult Action(string[] columns)
{

}

how do I do it?

Answer 1

Google is my friend ;)

http://server/controller/action/?columns[]=firstname&columns[]=lastname&columns[]=age 

Edit:

Actually you just write as I did in my original question. The reason to why I didn't get it working in the first place is that I used "column" in the query string and "columns" in as action parameter.
