What Is The Problem??

Question

VendorDetailModel Looks Like this

public class VendorDetailModel()

{

  public VendorDetailModel()

{

 vendorRatingModel = new List();

}

public List vendorRatingModel{ get; set; }

}

 public class VendorRatingModel
    {
        public int Count { get; set; }

        public int Rating { get; set; }
    }

 What is The Problem in service query is getting proper data but in controller it is vendorRating is null as shown
