Binding Querystring parameters in MVC

Question

Is there an equivalent way to bind querystring parameters in an MVC Controller to FromUri, which it seems is only used in MVC API?

I have 2 pages that can have from 0 to 7 querystring parameters, depending on filters that the user selects. I am trying to find a clean effective way to manage the querystring parameters from the controller without having a bunch of if statements. The parameters are basically the same for each page so creating a queryParameter class that both pages can access would be ideal.

It's really easy in an API controller and I would like to do something similar.

Any ideas would be appreciated.

Thanks,

Rhonda

Edit.

Say I have the following class:

public class QueryStringParams : IEnumerable
{
    public string Page { get; set; }
    public string Top { get; set; }
    public string Color { get; set; }
    public string Size { get; set; }
    public string Width { get; set; }
    public string Price { get; set; }
    public IEnumerator GetEnumerator()
    {
        yield return this.Page;
        yield return this.Top;
        yield return this.Color;
        yield return this.Size;
        yield return this.Width;
        yield return this.Price;
    }
}

In In my controller(s) I would like to have something like this:

public async Task Index(string pathAlias, [Bind(Prefix = "QueryStringParams")]QueryStringParams queryParams)

Similar to being able to do this in an API method.

public async Task Get(string pathAlias, [FromUri]QueryStringParams queryParams)

Then reference the querystring parameters like: var pageNumber = queryParams.Page;

The querystring would look something like this:

http://localhost:12330/br/womens-dresses-shop?page=2&Top=10&color=red

It may or may not have all of the parameters set at any one time.

Is that more clear?

The model binding for query string parameters automatically happens in asp.net MVC. You need to be more clear on what you want to achieve exactly. — ataravati

Let's start by showing us what your controller action looks like, and the query string that you are using. — Brendan Green

I updated the original post including some code snippets and a better description of what I am trying to do. — Rhonda

@Rhonda - it is still unclear what you intend to do with the query string parameters. Your current class will work fine as a view model (see the link that Filipe Oriani provided). So you have the values in a class. Now what? It seems like that should be sufficient. — NightOwl888

While not 100% ideal, this seems to work.

public async Task Index(string pathAlias, [Bind(Include = "Page, Color")]BrowseQueryParams queryParams)

If I want to access all of the parmeters I can just do this: public async Task Index(string pathAlias, BrowseQueryParams queryParams) Which I think is what someone was trying to say in one of the comments. I was trying to over complicate things.
