Nested object issue read from excel file

Hi There, I’m having issue with nested class to read from excel file.

When i read the file, i’m getting parse error for the class PriceDetail as a list. What is the mistake am i doing? thanks for your help.

I have attached the sample excel file as well.

string excelfilepath = fileDialog.FileName;
 var excel = new ExcelMapper(excelfilepath) { TrackObjects = true };
 excel.AddMapping<Products>("Mainproduct", p => p.Mainproduct);
 excel.AddMapping<Products>("Name", p => p.Name);
 excel.AddMapping<Products>("Visible", p => p.Visible);
 excel.AddMapping<Products>("NameIcon", p => p.NameIcon);
 excel.AddMapping<Products>("SysId", p => p.SysId);
 excel.AddMapping<PriceDetail>("ID", p => p.ID);
 excel.AddMapping<PriceDetail>("FromQuantity", p => p.FromQuantity);
 excel.AddMapping<PriceDetail>("Price", p => p.Price);
 excel.AddMapping<PriceDetail>("ServiceFee", p => p.ServiceFee);
 ProductPriceList = new ObservableCollection<Products>(excel.Fetch<Products>());
 View = CollectionViewSource.GetDefaultView(ProductPriceList);

 private ObservableCollection<Products> productpricelist;

        public ObservableCollection<Products> ProductPriceList
        {
            get { return productpricelist; }
            set
            {
                productpricelist = value;
                OnPropertyChanged("ProductPriceList");
            }
        }

	public class Products
	{
		public string SysId { get; set; }
		public string Mainproduct { get; set; }
		public string Name { get; set; }
		public string Visible { get; set; }
		public string From { get; set; }
		public List<PriceDetail> Prices { get; set; } = new List<PriceDetail>();
		public string NameIcon { get; set; }
	}

	public class PriceDetail
	{
		public string ID { get; set; }
		public string FromQuantity { get; set; }
		public string Price { get; set; }
		public string ServiceFee { get; set; }
	}

HI there, all good with small minor issue when i export the datagrid to excel just an empty col PriceDetail is created as its part of the class. I think i can delete this manually. Thanks so much for your help. Have a good day
