Question

How can I do the following in C# with less lines of code? I’m just initializing a new list using the fields of elements in an existing collection, but modifying each field before I add it to the list.

            List<string> itemDescriptions = new List<string>();
            foreach (CoolItem item in _coolItems)
            {
                itemDescriptions.Add("* " + item.Description);
            }

I’m guessing lambda expressions…

Answer 1

this is the LINQ Expression for this :

var itemDescriptions = 
    _coolItems.Select(item => "* " + item.Description).ToList();
