Question

I have two model class:

public class SalesItem
{
   public string ProductName { get; set; }
   public double UnitPrice { get; set; }
   public int Quantity { get; set; }
}

public class ProductItem : INotifyPropertyChanged
{
   public string ProductName { get; set; }
   public double UnitPrice { get; set; } 
}

I have a list of SalesItem, List<ProductItem> products, how can I cast it to List<SalesItem> sales

---

EDITED

List<ProductItem> salesList = new List<ProductItem>();
List<SalesItem> salesItem = salesList.Cast<SalesItem>();

Error:

Connot implicitly convert type 'System.Collections.Generic.IEnumerable<Model.SalesItem>' to 'System.Collections.Generic.List<Model.SalesItem>'. An explicit conversion exists (are you missing a cast?

Answer 1

Tried and tested

Include namespace

using System.Linq;

and then

List<ProductItem> yourProductlist = new List<ProductItem>();

yourProductlist.Add(new ProductItem() { ProductName = "A", UnitPrice = 50 });
yourProductlist.Add(new ProductItem() { ProductName = "B", UnitPrice = 150 });

List<SalesItem> yourSaleslist = yourProductlist.Select(x => 
                           new SalesItem() { ProductName = x.ProductName, 
                                             UnitPrice = x.UnitPrice }).ToList();

See it working

Casting will work if ProductItem is inherited from SalesItem class
