You should have your view accept a string[] Model and pass this model from your controller to your view like this:

public ActionResult About()
{
  var model = System.Web.Security.Roles.GetAllRoles();                   
  return View(model);
}

In your view you'd have something like this (assuming you are using the Razor ViewEngine):

@model string[]

<ul>
@foreach(var role in model) 
{
   <li>@role</li>
}
</ul>

You can set a ViewBag

public ActionResult About()
{
      ViewBag.roles = System.Web.Security.Roles.GetAllRoles();                   
      return View();
}

and u can access this ViewBag object on the page by @ViewBag.roles

To display the list

foreach(var customrole in ViewBag.roles)
 {
    @customrole.Roles // This might be some property you need to display 
 }

This way it is showing System.String[] as output on view page. – Smoking monkey Jun 05 '14 at 08:37
You'll have to iterate through the list i have updated my answer check this post for displaying the ViewBag http://stackoverflow.com/questions/10521831/how-to-display-a-list-using-viewbag – Nikitesh Jun 05 '14 at 08:53

The View method takes a model which can be your string[].

public ActionResult About()
{
    var roles = System.Web.Security.Roles.GetAllRoles();

    return View(roles);
}

Then your view would look something like this

@model System.Array

@foreach (var role in Model)
{
    ...
}
