Can u explain a bit more?
In the collection you are adding an object of type say cls1, which has say n properties. you are trying to set value for the nth property?
Is it correct?

You can't add a field to items in a collection - you need to add the field to the definition of the item, then it will automatically be in each item you add. Normally, you do this at design time, not run time.

What are you trying to achieve here?

Hi there,

try this:

C#

IEnumerable<string> ReadLines()
{
     string s;
     do
     {
          s = Console.ReadLine();
          yield return s;
     } while (s != "");
}

IEnumerable<string> lines = ReadLines();
lines.Add("foo") // so what would this supposed to do??

What you can do, however, is creating a new IEnumerable object (of unspecified type), which, when enumerated, will provide all items of the old one, plus some of your own. You use Enumerable.Concat for that:

C#

items = items.Concat(new[] { "foo" });

All the best..
