Question

Given a class like this:

public class Stock
{
    public Stock() {}
    public Guid StockID { get; set; }
    public string Description { get; set; }
}

Lets say I now have a List<Stock>. If I would like to retrieve a list of all the StockIDs and populate it into a IEnumerable or IList. Obviously I can do this.

List<Stock> stockItems = new List<Stock>();
List<Guid> ids = new List<Guid>();

foreach (Stock itm in stockItems) 
{
    ids.Add(itm.StockID);
}

But is there some way I could use Linq to achieve the same result? I thought Distinct() might do it but couldn’t work out how to achieve the desired result.

Answer 1

var list = stockItems.Select(item => item.StockID).ToList();
