LINQ: How to declare IEnumerable[AnonymousType]?

Question

This is my function:

    private IEnumerable SeachItem(int[] ItemIds)
    {
        using (var reader = File.OpenText(Application.StartupPath + @\"         


        

Answer 1

One thing to remember is that LINQ statements use deferred execution. What that means is that your LINQ statement doesn't actually execute until you either iterate over it in a foreach statement or you call the .ToList() method on myLine.
For your example try changing:

return myLine;

To:

return myLine.ToList();
