LINQ - Add property to results

Is there a way to add a property to the objects of a Linq query result other than the following?

var query = from x in db.Courses
                select new
                {
                    x.OldProperty1,
                    x.OldProperty2,
                    x.OldProperty3,
                    NewProperty = true
                };

I want to do this without listing out all of the current properties of my object. There are many properties, and I don't want to have to update this code whenever I may change my class.

I am still learning with LINQ and I appreciate your suggestions.

Solution

  • Add it with partial classes:

    public partial class Courses
{
    public String NewProperty { get; set; }
}

    Then you can assign it after you've created the object.
