Action with a string array as parameter

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 d开发者_C百科o it?

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.

I don't know if it's the difference between get and post parameters, but your original post works perfectly good with post parameters. In fact, when using []'s in post parameters the array becomes null in the action parameter. I found this out when jQuery 1.4 started adding []'s in json arrays when posting.
