Using a Lambda Expression with RemoveWhere

The following code removes all even values by using a lambda expression for the Predicate(T).

C#

HashSet<int> hs = new HashSet<int>(new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9 }); hs.RemoveWhere(item => { return (item % 2) == 0; });

Visual Basic

Dim hs As New HashSet(Of Integer)(New Integer() {1, 2, 3, 4, 5, 6, 7, 8, 9}) hs.RemoveWhere(Function(x) x Mod 2 = 0)

The set contains [ 1, 3, 5, 7, 9 ] after the RemoveWhere call completes.
