How do I change the text on an object property of a generic list of objects?
If Ive got a generic list of objects and I want to change the text on one of those objects properties, how do I do it?

class Prod
{
public Prod()
{
}
public int Id { get; set; }
public string Title { get; set; }
}
var prd = new List<Prod>();
var prd1 = new Prod {Id = 1, Title = "MY TITLE"};
var prd2 = new Prod { Id = 2, Title = "SOME THING" };
prd.Add(prd1);
prd.Add(prd2);
//this doesn't work - i assume because the lambda is trying to change the object, not the property
prd.ForEach(x => x.Title.ToLower());
foreach (var p in prd)
Console.WriteLine(string.Format("id={0} title={1}", p.Id, p.Title));

basically it wasn't modifying it because ToLower() returns a string it doesn't modify the string that it is referencing.
Change line 10 to:
prd.ForEach(x => x.Title = x.Title.ToLower());
Curses! Foiled by p_davis again :)

happens to me all the time.
prd.ForEach(delegate(Prod p1)
{
p1.Title = p1.Title.ToLower();
});
