Display output from ActionResult in html.TextBox

I've created a small Action in my HomeController to get the skills relating to a User, which the puts this into an Array.

    public ActionResult GetAllKeySkills()
    {

        string currentUserId = User.Identity.GetUserId();
        var user = db.Users.FirstOrDefault(u => u.AspNetId == currentUserId).UserId;

        var query1 = (from t in db.SkillRoleUsers
                      join s in db.Skills on t.SkillId equals s.SkillId
                      where t.UserId == user
                      select s.SkillName);

         return View(System.Tuple.Create(query1.ToArray()));
    }

I need this Array to now appear on a page in a TextBox to allow me to apply the Tag-Editor style I have set up.

I was going with something like this, but no dice.

  @Html.TextBox("KeySkills", 
                 @Html.Action("GetAllKeySkills", "Home"), 
                 null, 
                 new { htmlAttributes = new { @class = "skills" } })

I've also tried to use a ViewModel, but really don't understand how they work. Any other ideas?
