Examples

Shows how to calculate working hours.

var project = new Project(DataDir + "CalculateWorkHours.mpp");

// Access Task By Id
var task = project.RootTask.Children.GetById(1);

// Access Calendar and it's start and end dates
var taskCalendar = task.Get(Tsk.Calendar);
var startDate = task.Get(Tsk.Start);
var endDate = task.Get(Tsk.Finish);

// Access resource and their calendar
var resource = project.Resources.GetByUid(1);
var resourceCalendar = resource.Get(Rsc.Calendar);

TimeSpan timeSpan;

// Get Duration in Minutes
double durationInMins = 0;
var tempDate = startDate;
while (tempDate < endDate)
{
    if (taskCalendar.IsDayWorking(tempDate) && resourceCalendar.IsDayWorking(tempDate))
    {
        timeSpan = taskCalendar.GetWorkingHours(tempDate);
        durationInMins += timeSpan.TotalMinutes;
    }

    tempDate = tempDate.AddDays(1);
}

tempDate = startDate;

// Get Duration in Hours
double durationInHours = 0;
while (tempDate < endDate)
{
    if (taskCalendar.IsDayWorking(tempDate) && resourceCalendar.IsDayWorking(tempDate))
    {
        timeSpan = taskCalendar.GetWorkingHours(tempDate);
        durationInHours += timeSpan.TotalHours;
    }

    tempDate = tempDate.AddDays(1);
}

// Get Duration in Days
double durationInDays = 0;
tempDate = startDate;
while (tempDate < endDate)
{
    if (taskCalendar.IsDayWorking(tempDate) && resourceCalendar.IsDayWorking(tempDate))
    {
        timeSpan = taskCalendar.GetWorkingHours(tempDate);
        if (timeSpan.TotalHours > 0)
        {
            durationInDays += timeSpan.TotalDays * (24 / timeSpan.TotalHours);
        }
    }

    tempDate = tempDate.AddDays(1);
}

Console.WriteLine("Duration in Minutes = " + durationInMins);
Console.WriteLine("Duration in Hours = " + durationInHours);
