What is the cheapest way to execute a LINQ-Query immediately

Question

This question came into my mind while generating sample data for a SO-answer. I don\'t like the verbose way of adding DataRows one by one via Tbl.Rows.Add, so i\'ve

Answer 1

I'd just rewrite it as a foreach:

For Each y As String in years
    tbl.Rows.Add(y)
Next

It's much more clear what your intention is this way, and it executes right away.

Answer 2

I'd be more tempted to use a List(Of T):

Dim years As New List(Of String) From {"2010/2009", "2009/2008", "2008/2007", "2007/2006", "2006/2005", "2005/2004", "2004/2003"}

years.ForEach(Sub(y) tbl.Rows.Add(y))

It's all subjective though, loops are probably most clear for these one liners.
