How to use Html.Action's RouteValueDictionary values in controller - asp.net-mvc

Question

Here i am using Html.Action to display a set of books in (Books.cshtml) partial page.
I am passing Route Dictionary values in action but I don't have any idea about how to get Route Dictionary values in Controller and also is it possible to get Route Dictionary values in Partial page("Books.cshtml").
Index.cshtml
#{RouteValueDictionary objRoute = new RouteValueDictionary();
objRoute.Add("Book1", "DavinciCode");
objRoute.Add("Book2", "Pirates");
objRoute.Add("Book3", "Ghost");
}
#Html.Action("Books", "Home", objRoute)
Books.cshtml(Partial Page)
<p style="color:Blue;">
The list of books are as folows
<p># Book items</p>
//Here I need to display list of books (i.e) routevalue Dictionary values
</p>
HomeController:
public ActionResult Books()
{
return PartialView();
}

Answer 1

I don't think using a RouteValueDictionary to store your model in is the best idea. You can use a model with your partial view too, you know.
I would make a model for the partial view, which represents the data you need, i.e. a list of Books. On the Book, you put the necessary data for each book, including the key needed to display the detail view of the book (i.e. an Id property):
public class Book
{
public int Id { get; internal set; }
public string Name { get; internal set; }
// ...
}
Then you make your partial view have a model of e.g. List<Book>, in Books.cshtml:
#model IList<Book>
<p style="color:Blue;">
The list of books are as follows:
<ul>
#foreach (var book in #Model)
{
#Html.ActionLink(book.Name, "BookDetails", new { id = book.Id })
}
</ul>

You should be able to access route data along the lines of:
ViewContext.RouteData.Values["controller"]

Try the below solution, Its working fine for me.
CONTROLLER :
public ActionResult Books()
{
Dictionary<int, string> books = new Dictionary<int, string>() {
{ 1, "ASP.NET MVC #" },
{ 2, "C#" },
{ 3, "Razor View" } };
return PartialView("Books", books);
}
PARTIAL VIEW :
#{
Layout = null;
}
#model Dictionary<int, string>
<h2>The list of books are as follows:</h2>
<ul>
#foreach (var book in #Model)
{
<li>#book.Value</li>
}
</ul>
IN VIEW ( Wherever you want to display the list of books)
#Html.Action("Books", "YOURCONTROLLERNAME")

Answer 4

They should appear as method arguments - you just have to declare the ones you're interested in:
public ActionResult Books(string Book1, string Book2, string Book3)
{
return PartialView();
}
