Using Tree Algorithm in Aspose.Tasks

Introduction

Aspose.Tasks for .NET provides powerful functionalities for working with project management tasks, resources, and schedules. One such feature is the Tree Algorithm, which allows users to manipulate task hierarchies efficiently. In this tutorial, we’ll explore how to utilize the Tree Algorithm in Aspose.Tasks for .NET to gather common work and update work values within a project.

Prerequisites

Before we begin, ensure that you have the following prerequisites in place:

1. Visual Studio: Make sure you have Visual Studio installed on your system.
2. Aspose.Tasks for .NET: Download and install Aspose.Tasks for .NET from here.
3. Basic understanding of C#: Familiarity with C# programming language is required to follow along with the examples.

Import Namespaces

In your C# project, import the necessary namespaces to work with Aspose.Tasks functionalities:

using Aspose.Tasks;
using System;

using Aspose.Tasks.Util;

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

Step 1: Load Project File

var project = new Project(DataDir + "Project1.mpp");

Load the project file into memory using the Project class.

Step 2: Define Task Hierarchy

var root = project.RootTask.Children.Add("Project Management");
var summary = root.Children.Add("Manage iteration");
var task = summary.Children.Add("Acquire staff");

Define the task hierarchy by adding parent and child tasks.

Step 3: Set Task Properties

task.Set(Tsk.Start, new DateTime(1999, 5, 3, 9, 0, 0));
task.Set(Tsk.Duration, project.GetDuration(8 * 14, TimeUnitType.Hour));
task.Set(Tsk.Finish, project.Get(Prj.Calendar).GetFinishDateByStartAndWork(task.Get(Tsk.Start), task.Get(Tsk.Duration)));

Set properties such as start date, duration, and finish date for tasks.

Step 4: Add Resource

var resource = project.Resources.Add("Project Manager");
resource.Set(Rsc.Type, ResourceType.Work);
project.ResourceAssignments.Add(task, resource);

Add resources to the project and assign them to tasks as needed.

Step 5: Apply Tree Algorithm

var acc = new WorkAccumulator();
TaskUtils.Apply(summary, acc, 0);

Initialize the WorkAccumulator class and apply the Tree Algorithm to gather common work.

Step 6: Update Task Work

var summaryWork = acc.Work.ToDouble();
summary.Set(Tsk.Work, project.GetWork(summaryWork));
summary.Set(Tsk.RemainingWork, project.GetWork(summaryWork));

Update the work values for tasks based on the gathered information.

Conclusion

In this tutorial, we’ve learned how to utilize the Tree Algorithm in Aspose.Tasks for .NET to manipulate task hierarchies effectively. By following the step-by-step guide, you can efficiently manage tasks and resources within your projects.
