MVC Calling a view from a different controller

My project structure is like:

• Controllers/ArticlesController.cs
• Controllers/CommentsController.cs
• Views/Articles/Read.aspx

Read.aspx takes a parameter say "output", which is the details of the article by id and its comments, passed from ArticlesController.cs

Now I want to write then read the comment:: write() & Read() funct in CommentsController.cs

For reading the article with its comments, I want to call Views/Articles/Read.aspx from CommentsController.cs by passing output parameter from CommentsController.cs

How can I do this?

UPDATE

Code Here:

public class CommentsController : AppController
{
    public ActionResult write()
    {
        //some code
        commentRepository.Add(comment);
        commentRepository.Save();

        //works fine till here, Data saved in db
        return RedirectToAction("Read", new { article = comment.article_id });
    }

    public ActionResult Read(int article)
    {   
        ArticleRepository ar = new ArticleRepository();
        var output = ar.Find(article);

        //Now I want to redirect to Articles/Read.aspx with output parameter.
        return View("Articles/Read", new { article = comment.article_id });
    }
}

public class ArticlesController : AppController
{   
    public ActionResult Read(int article)
    {
        var output = articleRepository.Find(article);

        //This Displays article data in Articles/Read.aspx
        return View(output);
    }
}
