How to use access all rows of type List<T> in C# .NET Framework?

Question

I have a Model called SalesItemModel which has properties such as SaleItemId, SalesID, ProductID, Quantity, and UnitPrice. I pull list from database using SalesItemService.ListSalesItemsDataBySaleID(salesID).

public class SalesItemModel
{
    public int SalesItemID { get; set; }
    public int SalesID { get; set; }
    public int ProductID { get; set; }
    public string ProductName { get; set; }
    public Nullable<decimal> UnitPrice { get; set; }
    public double Quantity { get; set; }

}

Pulling Sales Items:

var salesItem = SalesItemService.ListSalesItemsDataBySaleID(SalesID);

And I want to access quantity and product ID of every row of the returned list to edit data on stock table using those data.

If you just want to access the data in list, you can try the below loop.

foreach(var item in salesItem)
{
item.Quantity = 10;
item.ProductId = 20;
}
