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

The method signature on SearchItem indicates that the method returns an IEnumerable but the anonymous type declared in your LINQ query is not of type string. If you want to keep the same method signature, you have to change your query to only select strings. e.g.

return myLine.Select(a => a.Text);

If you insist on returning the data selected by your query, you can return an IEnumerable
