MVC'Autofac.Core.Activators.Reflection.DefaultConstructorFinder'中找不到任何构造函数

Question

When I try to run MVC I get the following error:

None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'A105004P.Controllers.AssessPersonController' can be invoked with the available services and parameters: Cannot resolve parameter 'Library.Interface.IAssessPerson AssessPerson' of constructor 'Void .ctor(Library.Interface.IAssessPerson)'.

Here are the relevant files:

How to fix it?Thank you.

The problem is fixed. Here is Answer below:

   public class SYMController : Controller
{
    ISYM _ap;
    IttaessData _ad;
    public SYMController()
    {
        _ap = new LISYM();
        _ad = new LIttaessData();
    }
    public int pageSize = 15;
    public ActionResult Index(int? page, string name)
    {
        IList<ISYM> list = _ap.getDataList();
        var query = (from item in list
                     select new SYMViewModel
                     {
                         id = item.id,
                         tta_name = item.tta_name,
                         gender = item.gender,
                         unitname = item.unitname,
                         jobtitle = item.jobtitle,
                         servicestate = item.servicestate,
                         phone = item.phone,
                         enable=item.enable
                     }).ToList();
        foreach (var item in query)
        {
            item.tta_name = item.tta_name == null ? "" : item.tta_name;
        }
        if (!string.IsNullOrEmpty(name))
        {
            query = query.Where(a => a.tta_name.Contains(name)).ToList();
        }
        query = query.Where(a => a.enable==true).ToList();
        var result = query
            .OrderByDescending(x => x.tta_name)
            .ThenBy(x => x.tta_name).ToPagedList(page ?? 1, pageSize);
        var num = query.Count();
        ViewBag.pageSize = pageSize;
        ViewBag.page = page;
        ViewBag.num = num;
        ViewBag.count = query.Count();
        ViewBag.name = name;
        return View(result);
    }
    public ActionResult Detail(int id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        SYMViewModel APVM = new SYMViewModel();
        ISYM IA = _ap.getSYMId(id);
        getFile(IA.picfile, IA.id);
        IList<IttaessData> list = _ad.getDataList();
        var ttaessdata = (from AD
