See if you can use ci.subject..IndexOf(temp,StringComparison.CurrentCultureIgnoreCase) >= 0;.

.NET list doesn't support explicitly setting comparer used.This means that you should work around this.You have several ways to solve the problem:
1.work in uppercase/lowercase only.
2.scan manually the list and use String.Compare instead of IList.Contains.
3.Implement proper comparer of your collection elements.You could do it by implementing IComparer or IComparable.

Solution 2

I don't know if this will work, as I haven't tried it myself, but you could try something like

C#

(from ci in list
where ci.Subject.ToUpper().Contains(emailSubject.ToUpper())
select ci).ToList();
