ASP.NET MVC - How to pass an Array to the view?

Question

Hello there, I'm struggling myself here, to find a easy way to pass an array from the controller to the view on ASP.NET MVC framework.

so in my controller I would have something like:

public class HomeController : ApplicationController
{   
    public ActionResult Index()
    {
        string[] myArray = { "value01", "value02", "value03"};
        ViewData["passedArray"] = myArray;
        return View();
    }
}

so in my view I would have just a call to ViewData["passedArray"] and run a loop on it.

But apparently the ViewData is being received by the view as System.String, probably because of the declaration on the Array DataType, but unfortunately I don't know how to pass it properly and simply without create millions of code lines.

It would be fantastic if one could help me.

Thanks in advance

Answer 1

This should work by casting ViewData["passedArray"] within the view to string[]. Alternatively, if you want to go the extra mile: create a ViewModel class that contains this array as a member and pass that ViewModel to a strongly-typed version of your view.

Answer 2

You need to cast in the View

<% var myArray = (string[])ViewData["passedArray"]; %>
