In VB.NET 9.0 Lambda is one of the features we have here. Lambda expression is just another way to call Anonymous method/delegate.
Let’s look into a generic list of integers, and play with it,
Dim arrInt As New List(Of Integer)
For i As Integer = 1 To 10
When you need to get the even numbers out of this List, you can call delegate,
Dim even1 As New List(Of Integer)
even1 = arrInt.FindAll(New Predicate(Of Integer)(AddressOf EvenGetter))
Then for this approach you need a method,
Public Function EvenGetter(ByVal i2 As Integer) As Boolean
Return i2 Mod 2 = 0
Using VB.NET 9.0 you can also implement Lambda Expression,
even1 = arrInt.FindAll(Function(i2 As Integer) i2 Mod 2 = 0)

Thanks. Was trying to figure out the syntax for lambda expression in vb.net as i'm a c# guy.
How do I convert thefollowing c# code to VB.Net using Lambda Expression:
synchronizationContext.Post((e) => action((T)e), eventArgs);
synchronizationContext.Post((Function(e as T) action(e)), eventArgs)
Very Good! Thanks you very much!
Now I understand on 'Lambda' clearly.
