Linq To DataSet getting error

Question

In my WinForm project, I try to access to the table in DataSet with help of LINQ.

      DSObjectData lDataSetObject; // DSObjectData -Strongly typed DataSet

       var q = from contour in lDataSetObject.Contour
               select contour;

But on select operator I get this error:

Cannot convert lambda expression to type 'string' because it is not a delegate type

Is the `Contour` `DataTable`? – Hamlet Hakobyan Jan 13 '13 at 14:37 — Hamlet Hakobyan, Jan 13 '13 at 14:37

DataTable is not Enumerable.

var q = from contour in lDataSetObject.Contour.AsEnumerable()
               select contour;

q is IEnumerable<DataRow>.

No, it is not enumerable. What you want to enumerate in DataSet? – Hamlet Hakobyan Jan 13 '13 at 14:55
