Accessing querystring in ASP.NET MVC6

I am trying to access query string parameters in my ASP.NET MVC6 applications. But it seems unlike MVC5 and web forms, QueryString doesn't have any indexer and I can't say something like:

string s = Request.QueryString["key1"] //gives error

So, my question is - how do I access query string parameters in MVC6?

Surprisingly Request.Forms collection works as expected (as in MVC5 or web forms).

Thank you.

You can use Request.Query which is new addition in ASPNET 5.

 var queryStrings = Request.Query;

The URL I am going to try was - http://localhost:12048/Home/Index?p=123&q=456 And you can get All Keys using - 

queryStrings.Keys

enter image description here

And then you can get the values by iterating keys - 

 var qsList = new List<string>();
 foreach(var key in queryStrings.Keys)
 {
      qsList.Add(queryStrings[key]);
 }

enter image description here

Getting query with an indexer is supported.

See MVC code test here - https://github.com/aspnet/Mvc/blob/e0b8532735997c439e11fff68dd342d5af59f05f/test/WebSites/ControllersFromServicesClassLibrary/QueryValueService.cs

context.Request.Query["value"];

Also note that in MVC 6 you can model bind directly from query by using the [FromQuery] attribute.

public IActionResult ActionMethod([FromQuery]string key1)
{
    ...
}
