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 class SkillsVMsController : Controller
{
    private NextrungContext db = new NextrungContext();

    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);
        SkillsVM model = new SkillsVM();
        model.KeySkills = query1.ToArray();
        return View(model);
    }

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 (and again as below), but really don't understand how they work.

SkillsVM

namespace NextRung.Models
{
    public class SkillsVM
    {
        [Key]
        public Int32 LinkId { get; set; }
        public Int32 SkillId { get; set; }
        public string SkillName { get; set; }
        public string SkillLongDesc { get; set; }
        public bool KeySkill { get; set; }

        public string Email { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        [DataType(DataType.Date)]
        public DateTime DateOfBirth { get; set; }
        public string Address1 { get; set; }
        public string Address2 { get; set; }
        public string Address3 { get; set; }
        public string Address4 { get; set; }
        public string Address5 { get; set; }
        public string PostCode { get; set; }
        public string PhoneMobile { get; set; }
        public string PhoneOther { get; set; }
        [DisplayFormat(NullDisplayText = "No Summary yet")]
        public string Summary { get; set; }



        public Int32? RoleId { get; set; }
        public Int32? UserId { get; set; }
        public Int32? CritVitId { get; set; }
        public Int32? VacancyId { get; set; }

        public string[] KeySkills { get; set; }
    }
}

Any other ideas?
