LINQ, Where() vs FindAll()

Question

Can someone explain how the LINQ functions Where(..) and FindAll(..) differ? They both seem to do the same thing...

Answer 1

The biggest difference to me is that .FindAll is also available in .Net 2.0. I don't always have the luxury to program in .Net 3.5, so I try to remember the 'native' methods of the .Net generic collections.

It happened several times that I implemented an already available List method myself because I couldn't LINQ it.

What I find handy in this case is that, using VS2008, I can use type inference and the lambda syntax. These are compiler features, not framework features. This means I can write this and still remain within .Net 2.0:

var myOddNums = myNums.FindAll(n => n%2==1);

But if you do have LINQ available, keeping the difference between deferred execution and immediate execution is important.
