Lightbulb LINQ to Dataset (VB 2102)

I am trying to implement basic examples of LINQ to Dataset

ds is an existing, full dataset (one table)
PKName is the name of a COLUMN in the table
PKValue is the value of that column

Dim dt As DataTable = ds.Tables(0)

query = _
From ele In dt.AsEnumerable() _
Where ele.Field(Of Int16)(PKName) = PKValue _
Select ele

I want now to browse through the results.

for each e in query
console.writeline(e.ele)
next e

but the compiler claims "e is not a member of System.Data.DataRow

In fact, given "e" (a row in a table) I need the columns named prefix1, prefix2, prefix3....

I am stuck on it and would appreciate any guidance.
thanks
