Question

I have this Linq statement:

List<string> phoneNumbers = from t
                            in fixedLineData
                            select t.phoneNumber.Distinct();

Basically what I want is a distinct list of strings sent back from the LINQ query.

Is this possible?

Answer 1

Make it

  var phoneNumbers =
      (from t in fixedLineData 
      select t.phoneNumber)
      .Distinct().ToList();

But you might as well skip the query-syntax:

 var phoneNumbers =
      fixedLineData 
      .Select (t => t.phoneNumber)
      .Distinct()
      .ToList();

The .ToList() will make the resulting type IList<string>
