Getting list of error messages from ModelState with Linq

Question

Is it possible to create one chained linq statements to create an IEnumerable(Of String) of error messages from ViewData.ModelState?

I have tried:

Dim errorlist = ViewData.ModelState.Select(
    Function(m) m.Value.Errors.Select(
        Function(e) e.ErrorMessage))

But that linq produces IEnumerable(Of IEnumerable(Of String)).

Try SelectMany instead of Select
