Managing Day Type Collection in Aspose.Tasks

Introduction

Aspose.Tasks for .NET provides robust functionality for managing day type collections, crucial for defining weekly calendar exceptions in project management applications. In this tutorial, we’ll explore how to utilize the DayTypeCollection class efficiently.

Prerequisites

Before we proceed with the tutorial, make sure you have the following prerequisites:

1. Visual Studio: Ensure you have Visual Studio installed on your system.
2. Aspose.Tasks for .NET: Download and install the Aspose.Tasks for .NET library from here.
3. Basic Knowledge of C#: Familiarity with C# programming language and .NET framework concepts.

Import Namespaces

To get started, you need to import the necessary namespaces into your C# project:

using Aspose.Tasks;
using System;

Now, let’s break down the provided example into multiple steps:

Step 1: Load Project and Access Calendar

var project = new Project(DataDir + "WeeklyDayTypeException.mpp");
var calendar = project.Calendars.GetByUid(1);

This step initializes a new project instance and retrieves the calendar by its UID.

Step 2: Iterate Through Calendar Exceptions

foreach (var calendarException in calendar.Exceptions)
{
    Console.WriteLine("Exception Name: " + calendarException.Name);
    Console.WriteLine("Days of week count: " + calendarException.DaysOfWeek.Count);
    foreach (var dayType in calendarException.DaysOfWeek)
    {
        Console.WriteLine("Day type: " + dayType);
    }
    Console.WriteLine();
}

Here, we iterate through each calendar exception and print its name and associated day types.

Step 3: Modify Calendar Exceptions

var exc1 = calendar.Exceptions.ToList()[0];
if (!exc1.DaysOfWeek.IsReadOnly && exc1.DaysOfWeek.IndexOf(DayType.Monday) < 0)
{
    exc1.DaysOfWeek.Insert(0, DayType.Wednesday);
}

var exc2 = calendar.Exceptions.ToList()[1];
if (exc2.DaysOfWeek.Contains(DayType.Sunday))
{
    exc2.DaysOfWeek.Remove(DayType.Sunday);
}

Console.WriteLine("Remove " + exc2.DaysOfWeek[0] + " day type from exception by index...");
exc2.DaysOfWeek.RemoveAt(0);

This step demonstrates how to modify calendar exceptions by adding, removing, or updating day types.

Step 4: Create and Manipulate New Calendar Exceptions

var exc4 = new CalendarException
{
    Name = "Weekly Exception 2",
    FromDate = new DateTime(2020, 4, 13),
    ToDate = new DateTime(2020, 4, 18),
    Occurrences = 3,
    Type = CalendarExceptionType.Weekly
};
exc4.DaysOfWeek.Add(DayType.Monday);
exc4.DaysOfWeek.Add(DayType.Thursday);

calendar.Exceptions.Add(exc4);

var exc3 = calendar.Exceptions.ToList()[2];

exc3.DaysOfWeek.Clear();

var dayTypes = new DayType[exc4.DaysOfWeek.Count];
exc4.DaysOfWeek.CopyTo(dayTypes, 0);

foreach (var dayType in dayTypes)
{
    exc3.DaysOfWeek.Add(dayType);
}

Console.WriteLine("Days of week for exception: " + exc3.Name);
foreach (var dayType in exc3.DaysOfWeek)
{
    Console.WriteLine("Day type: " + dayType);
}

In this final step, we create new calendar exceptions and manipulate them by adding and copying day types.

Conclusion

In conclusion, managing day type collections in Aspose.Tasks for .NET is essential for defining and modifying weekly calendar exceptions in project management applications. By following the step-by-step guide provided in this tutorial, you can effectively utilize the DayTypeCollection class to handle various calendar operations.
