Question

I have the following LINQ query in VB.NET

Using db As New ReablementLSQLDataContext
                query = (From b In db.Visits
                             Join c In db.LinkStaffToVisits On b.ID Equals c.VisitID
                             Where c.StaffID = staffid And b.StartEpoch = newepochdatetime).ToList()

            End Using

When I run this, it returns a list of type anonymous which means its pretty useless if I want to access any of the data in it. How do I run this join statement and return a list of a concrete type?

Answer 1

Anonymous types as query results aren’t so “useless”, since you can always foreach over them (locally). Still, if you want a concrete type, you can add a select statement at the end and project the anonymous result into your type (supposed that you made this type and know which fields to use where), like (C# syntax)

var newQuery = query.Select(anon_x => new YourType(anon_x.field1, anon_x.field2, ...))
