I have a List Say foo, which holds data of type Class A (containing members FName, LName, Total). I need to get the list of datas whose LName is "foobar".
I know this sounds a simple question, but this pisses me off! because the I will get the Members for returning the list in runtime.
Thanks in advance
EDIT : I am sorry Geeks, the List is Dyanamic the List is of Object type. I knows its of type Class A only during runtime
It can be easily done using LINQ:
using System.Linq;
(...)
List<A> foo = GetFooList(); // gets data
List<A> fooBorItems = foo.Where(a = > a.FName == "foobar").ToList();
Or using syntax based query:
List<A> fooBorItems = (from a in foo
where a.FName == "foobar"
select a).ToList();
For List<object> use Cast<T> extension method first. It will cast all source collection elements into A (and throw exception when it's not possible):
List<A> fooBorItems = foo.Cast<A>().Where(a = > a.FName == "foobar").ToList();
or OfType<A> (which will return only elements that can be casted, without exceptions for these that can't):
List<A> fooBorItems = foo.OfType<A>().Where(a = > a.FName == "foobar").ToList();
Cast<A>() or OfType<A>, because they both returns IEnumerable<A>
