Group a set of rows based on a column

Question

Hi I have case where I am getting the data from from my database and it looks like this:

I am using Entity Framework database first and a stored procedure to get this data.This is the model that I get back:

public partial class GetELearningSessionsForStudent_Result
{
    public int LessonNumber { get; set; }
    public string LessonTitle { get; set; }
    public Nullable<int> Status { get; set; }
    public Nullable<System.DateTime> TargetDate { get; set; }
    public string EventTitle { get; set; }
}

Now I would like to be able to group LessonNumber and use it as a key , that would contain the following:

     KEY                                   Data
{LessonNumber AND LessonTitle} {Status , TargetDate , EventTitle}

I have been trying to do this for hours and it feels that I am somehoe missing something. How can I achieve this?

Answer 1

Is this what you're looking for?

listOfItems.GroupBy(key => new { key.LessonNumber, key.LessonTitle },
     data => new {data.Status, data.TargetDate, data.EventTitle});
