Question

I’m trying to replace the classic For Each loop with the LINQ ForEach extension in VB.NET…

  Dim singles As New List(Of Single)(someSingleList)
  Dim integers As New List(Of Integer)

  For Each singleValue In singles
    integers.Add(CInt(Math.Round(singleValue)))
  Next singleValue

Maybe something like this?

  singles.ForEach(Function(s As [Single]) Do ???

How can I correctly do this using anonymous methods (i.e. without declare a new function)?

Answer 1

Try this:

singles.ForEach(Sub(s As [Single]) integers.Add(CInt(Math.Round(s))))

You need a Sub here, because the body of your For Each loop doesn’t return a value.
