C# 2.0 Iterators question

[Dilip]

Given a bunch of IEnumerable<Tobjects, how do I iterate through them
and do a yield return on objects that satisfy one condition and
objects that satisfy another condition? I am still wrapping my head
over C# 2.0 iterators and I am not able to get this right.

public static IEnumerable<TGetObjects(IEnumerable<Tobjects)
{
foreach(T x in objects)
{
yield return x;
}
}

that obviously returns everything. I went the Predicate<Troute and
that got me here:

public static IEnumerable<TGetObjects(IEnumerable<Tobjects,
Predicate<Tcondition)
{
foreach(T x in objects)
{
if (condition(x))
yield return x;
}
}

This works but it only returns objects that satisfy one condition.
What if I want all objects that return false too but on a different
call to GetObjects()?

Basically I am trying to find a way to use the same GetObjects()
function and vary the condition from the outside.

I can only work within the confines of .NET 2.0 (so no mindnumbing
LINQ suggestions :-))

thanks!
