ProjectSchedule

class.NET 6 / 8 / 10.NET Framework 4.8Binarymission.WPF.Controls.ProjectManagement

A plan as scheduled: every task's dates and float, the links that were honoured, the critical path, the project's start and finish, and anything in the input that could not be used.

public sealed class ProjectSchedule

Remarks

Get one from ProjectScheduler.Schedule(), or from a chart's Schedule property, which is the schedule the chart is drawing. A schedule is a snapshot: it does not change when the plan does. Schedule again (or read the chart's property again) after a change.

Nothing in it is ever null: an empty plan gives empty lists, and a plan with bad data gives everything that could be scheduled plus the Problems.

Examples

ProjectSchedule schedule = gantt.Schedule;

summaryText.Text = string.Format("{0:d} to {1:d}: {2} working days",
    schedule.ProjectStart, schedule.ProjectFinish, schedule.ProjectDuration);

// The work that cannot slip without moving the finish, in date order.
foreach (string id in schedule.CriticalPath)
{
    ScheduledTask task = schedule.Find(id);
    criticalList.Items.Add(task.Name + " - " + task.Finish.ToString("d"));
}
