How to dynamically choose two fields from a Linq query as a result
- by Dr. Zim
If you have a simple Linq query like:
var result = from record in db.Customer
select new { Text = record.Name,
Value = record.ID.ToString() };
which is returning an object that can be mapped to a Drop Down List, is it possible to dynamically specify which fields map to Text and Value?
Of course, you could do a big case (switch) statement, then code each Linq query separately but this isn't very elegant. What would be nice would be something like:
(pseudo code)
var myTextField = db.Customer["Name"]; // Could be an enumeration??
var myValueField = db.Customer["ID"]; // Idea: choose the field outside the query
var result = from record in db.Customer
select new { Text = myTextField,
Value = myValueField };
