Question

Here is the code:

cmbVegas.Items.AddRange((VegasPegasusCourseObject[])convertableCourses.ToArray());
cmbVegas.DisplayMember = "VegasCourseName";
cmbVegas.ValueMember = "CourseMapID";

convertableCourses is a List<VegasPegasusCourseObject>

This is where I am getting the List from:

public List<VegasPegasusCourseObject> GetConvertedCourses()
        {
            using (PanamaDataContext db = new PanamaDataContext())
            {
                IQueryable<VegasPegasusCourseObject> vegasCourses = from cm in db.VegasToPegasusCourseMaps 
                                   join c in db.Courses on cm.VegasCourseID equals c.CourseID
                                   join cp in db.Courses on cm.PegasusCourseID equals cp.CourseID
                                   select new VegasPegasusCourseObject
                                   {
                                       CourseMapID = cm.VPCMapID,
                                       VegasCourseName = c.CourseName,
                                       VegasCourseID = cm.VegasCourseID,
                                       PegasusCourseID = cm.PegasusCourseID,
                                       PegasusCourseName = cp.CourseName
                                   };

                return vegasCourses.ToList();
            }
        }

Here is the obj def:

class VegasPegasusCourseObject
    {
        public int CourseMapID;

        public string VegasCourseName;
        public int VegasCourseID;

        public string PegasusCourseName;
        public int PegasusCourseID;
    }

However when I fire this baby up this is all I am getting:

Answer 1

As per the comments above, the issue is due to the fact that “VegasCourseName” has been written as a field, not a property. Therefore, the ToString implementation has been shown instead.

Use a property instead:

class VegasPegasusCourseObject
{
    public string VegasCourseName { get; set;}
}
