MVC Calling a view from a different controller

My project structure is like:

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);
    }
}

It is explained pretty well here: Display a view from another controller in ASP.NET MVC

To quote @Womp:
By default, ASP.NET MVC checks first in \Views\[Controller_Dir]\, but after that, if it doesn't find the view, it checks in \Views\Shared.

ASP MVC's idea is "convention over configuration" which means moving the view to the shared folder is the way to go in such cases.

To directly answer your question if you want to return a view that belongs to another controller you simply have to specify the name of the view and its folder name.

public class CommentsController : Controller
{
    public ActionResult Index()
    { 
        return View("../Articles/Index", model );
    }
}

and

public class ArticlesController : Controller
{
    public ActionResult Index()
    { 
        return View();
    }
}

Also, you're talking about using a read and write method from one controller in another. I think you should directly access those methods through a model rather than calling into another controller as the other controller probably returns html.

I'm not really sure if I got your question right. Maybe something like

public class CommentsController : Controller
{
    [HttpPost]
    public ActionResult WriteComment(CommentModel comment)
    {
        // Do the basic model validation and other stuff
        try
        {
            if (ModelState.IsValid )
            {
                 // Insert the model to database like:
                 db.Comments.Add(comment);
                 db.SaveChanges();

                 // Pass the comment's article id to the read action
                 return RedirectToAction("Read", "Articles", new {id = comment.ArticleID});
            }
        }
        catch ( Exception e )
        {
             throw e;
        }
        // Something went wrong
        return View(comment);

    }
}


public class ArticlesController : Controller
{
    // id is the id of the article
    public ActionResult Read(int id)
    {
        // Get the article from database by id
        var model = db.Articles.Find(id);
        // Return the view
        return View(model);
    }
}

You can move you read.aspx view to Shared folder. It is standard way in such circumstances
