Retrieve TimeSheets of all users

Question

I have created a simple console C# application that retrieves TimeSheets of the admin user used in the Sharepoint athentification, but what i want to do is to retrieve all users TimeSheets for a certain period (TimeSheetPeriods), any ideas about how you can do this? any sample code?

here is my code may be i forgot something :

 

cntx.Load(cntx.Projects);
cntx.ExecuteQuery();
cntx.Load(cntx.TimeSheetPeriods, c => c.Where(p => p.Start <= DateTime.Now && p.End <= DateTime.Now).
    IncludeWithDefaultProperties(p => p.TimeSheet,
                                p => p.TimeSheet.Lines.Where(l => l.LineClass == TimeSheetLineClass.StandardLine).
    IncludeWithDefaultProperties(l => l.Assignment,
                                l => l.Assignment.Task,
                                l => l.Work)));


cntx.ExecuteQuery();
var myPeriod = cntx.TimeSheetPeriods.LastOrDefault();
if (myPeriod == null)
    throw new Exception("Please create the periods in your server settings");


foreach (var line in myPeriod.TimeSheet.Lines)
    {
        Console.WriteLine("ProjectName : "+line.ProjectName);
        Console.WriteLine("TaskName : " + line.TaskName);

    foreach (var work in line.Work)
        {
            Console.WriteLine("PlannedWork----->" + work.PlannedWork);

            Console.WriteLine("ActualWork----->" + work.ActualWork);

            Console.WriteLine("StartDate----->" + work.Start);

            Console.WriteLine("TaskComment----->" + work.Comment);

         }

    }
