Passing an array to the query string of the main ASP.NET route

Question

I want to do this , but I also want to pass arrays to the query string. I tried things like:

http://www.sitename.com/route?arr[]=this&arr[]=that
http://www.sitename.com/route?arr[]=this&that
http://www.sitename.com/route?arr[0]=this&arr[1]=that
http://www.sitename.com/route?arr0=this&arr1=that
http://www.sitename.com/route?arr=this&arr=that

And my route in C # code looks like this:

[Route("route")]
[HttpGet]
public void DoSomething(string[] values)
{
    // ...
}

But in all these cases, the values ​​are always zero when they fall into C # code. Why do I need a query string to pass an array of strings?
