Question

This feels like a completely basic question, but, for the life of me, I can’t seem to work out an elegant solution.

Basically, I am doing a LINQ query creating a new object from the query. In the new object, I want to generate a auto-incremented number to allow me to keep a selection order for later use (named Iter in my example).

Here is my current solution that does what I need:

    Dim query2 = From x As DictionaryEntry In MasterCalendarInstance _                  Order By x.Key _                  Select New With {.CalendarId = x.Key, .Iter = 0}      For i = 0 To query2.Count - 1         query2(i).Iter = i     Next 

Is there a way to do this within the context of the LINQ query (so that I don’t have to loop the collection after the query)?

Pardon me for doing this in C# not sure exactly the syntax in VB.NET:

MasterCalendarInstance     .OrderBy(x => x.Key)     .Select((x, ixc) => new { CalendarId = x.Key, Iter = ixc });
