Dynamically mapping a model to a view

I have a partial view working with a strongly typed model. Is it possible to map my model to my partial view on the fly in a html helper method and return the rendered html?

Here is the pseudo code that I'm wondering if it's possible.

    public static MvcHtmlString ContentRating(this HtmlHelper html, ContentKey contentKey)
    {
        ContentRatingModel contentRatingModel = new ContentRatingHelper().GetContentRatingModel(contentKey);

        // map my partial view which is named "ContentRating.cshtml" to contentRatingModel    

        return new MvcHtmlString(string.Format("the html output of mapping");
    }

And use this helper method in my views as below:

@Html.ContentRating(ContentKey.Test)

It's not quite clear what exactly you mean by mapping a partial view to a model but if you want to render the contents of this partial view inside your helper you could do the following:

public static MvcHtmlString ContentRating(this HtmlHelper html, ContentKey contentKey)
{
    ContentRatingModel contentRatingModel = new ContentRatingHelper().GetContentRatingModel(contentKey);

    var result = html.Partial("ContentRating", contentRatingModel);

    return new MvcHtmlString(result.ToHtmlString());
}

Don't forget to bring the System.Web.Mvc.Html namespace in scope so that the Partial extension method could be resolved in your custom helper:

using System.Web.Mvc.Html;
