Мигрируйте в Aspose.tasks для .net 8.0+

Aspose.tasks для .NET 8.0.0 - это обновленная версия API, которая включает в себя значительные изменения с точки зрения использования. Ключевые различия обеих реализаций включают:

Legacy API разрешил устанавливать общественные области различных классов данных проекта, таких как проект, задачи, ресурсы и т. Д., В то время как новая реализация вводит набор и получение методов для достижения того же самого
Пользователь, которые должны называться вручную, пересчитывайте вручную в API Legacy после определенных операций, таких как назначение ресурсов. Новый Aspose.tasks для .NET API выполняет большинство таких вычислений автоматически без необходимого пользовательского вмешательства.
Новый API обеспечивает ручные, а также автоматические режимы пересчета, аналогичные Microsoft Project (MSP). Ручной режим рассчитывает только необходимые поля, тогда как автоматический режим пересматривает все. Это устраняет необходимость вызова вручную пересчитывания методов и улучшает общее использование API.

Этот новый API несовместим с API Legacy, и цель этой статьи - помочь вам перенести ваш код в новый API. В статье показаны сравнительные образцы кода наследия и новую реализацию API и включает в себя:

Настройка свойств проекта по умолчанию

Aspose.tasks ‘Legacy API позволил установить свойства по умолчанию проекта путем непосредственной установки публичных атрибутов класса проекта. Однако в новой реализации API он выставляет настройки и получает методы для достижения того же самого.

Creating and Adding Calendar to a Project

In order for proper functionality of Calendar items added to the Project, the legacy API required to recalculate Calendar UIDs. In the new API, however, UIDs recalculation are automatically dealt and there is no need to call the calculations manually.

Legacy API Code Sample

 1    Project prj =  new Project();
 2    Aspose.Tasks.Calendar cal1 = new  Aspose.Tasks.Calendar();
 3    cal1.Name ="no info";
 4    Aspose.Tasks.Calendar cal2 = new  Aspose.Tasks.Calendar(1);
 5    cal2.Name = "no name";
 6    Aspose.Tasks.Calendar cal3 = new  Aspose.Tasks.Calendar( "cal3" );
 7    prj.Calendars.Add(cal1);
 8    prj.Calendars.Add(cal2);
 9    prj.Calendars.Add(cal3); 
10    prj.Save( "Project.Xml", Aspose.Tasks.Saving.SaveFileFormat.XML);

 1    'Create a project instance
 2    Dim prj As New Project()
 3    'Define Calendar
 4    Dim cal1 As New Aspose.Tasks.Calendar()
 5    cal1.Name = "no info"
 6    Dim cal2 As New Aspose.Tasks.Calendar(1)
 7    cal2.Name = "no name"
 8    Dim cal3 As New Aspose.Tasks.Calendar("cal3")
 9    prj.Calendars.Add(cal2)
10    prj.Calendars.Add(cal3)
11    prj.CalcCalendarUids()
12    'Save the Project
13    prj.Save("Project.Xml", Aspose.Tasks.Saving.SaveFileFormat.XML)

3    Project prj = new Project();
4    Aspose.Tasks.Calendar cal1 = prj.Calendars.Add("no info");
5    Aspose.Tasks.Calendar cal2 = prj.Calendars.Add("no name");
6    Aspose.Tasks.Calendar cal3 = prj.Calendars.Add("cal3");
7    prj.Save("Project.Xml", Aspose.Tasks.Saving.SaveFileFormat.XML);

1    'Create a project instance
2    Dim prj As New Project()
3    Dim cal1 As Aspose.Tasks.Calendar = prj.Cal 
4    Dim cal2 As Aspose.Tasks.Calendar = prj.Calendars.Add("no name")
5    Dim cal3 As Aspose.Tasks.Calendar = prj.Calendars.Add("cal3")
6    prj.Save("Project.Xml", Aspose.Tasks.Saving.SaveFileFormat.XML)

Making A Standard Calendar

Recalculating Calendar UIDs are no more required in the new ASpose.Tasks’ API as compared to the legacy API.

Legacy API Code Sample

 1 
 2
 3    //Create a project instance
 4    Project prj = new  Project();
 5    //Define Calendar and make it standard
 6    Aspose.Tasks.Calendar cal1 = new  Aspose.Tasks.Calendar("My Cal");
 7    Aspose.Tasks.Calendar.MakeStandardCalendar(cal1);
 8    prj.Calendars.Add(cal1);
 9    prj.CalcCalendarUids();
10    prj.Save( "Project.Xml" , Aspose.Tasks.Saving.SaveFileFormat.XML);

1    'Create a project instance
2    Dim prj As New Project()
3    'Define Calendar and make it standard
4    Dim cal1 As New Aspose.Tasks.Calendar("My Cal")
5    Aspose.Tasks.Calendar.MakeStandardCalendar(cal1)
6    prj.Calendars.Add(cal1)
7    prj.CalcCalendarUids() 
8    prj.Save("Project.Xml", Aspose.Tasks.Saving.SaveFileFormat.XML)

New Aspose.Tasks for .NET 8.x Approach

1    // Create a project instance
2    Project project = new Project();
3
4    // Define Calendar and make it standard
5    Aspose.Tasks.Calendar cal1 = project.Calendars.Add("My Cal");
6    Aspose.Tasks.Calendar.MakeStandardCalendar(cal1);
7    project.Save("Project.Xml", Aspose.Tasks.Saving.SaveFileFormat.XML);

1    'Create a project instance
2    Dim project As New Project()
3
4    'Define Calendar and make it standard
5    Dim cal1 As Aspose.Tasks.Calendar = project.Calendars.Add("My Cal")
6    Aspose.Tasks.Calendar.MakeStandardCalendar(cal1)
7
8    'Save the Project
9    project.Save("Project.Xml", Aspose.Tasks.Saving.SaveFileFormat.XML)

Create and Add Task to Project

Creating a new task in the legacy API, it required to define a root task, add it to the project as its root task, and then add a new task to this root task as a child. The new API, however, doesn’t need you to define the root task and takes care of it automatically while adding the first task to the project.

Legacy API Code Sample

 1    Project project = new Project();
 2    Task rootTask = new Task();
 3    Task tskGen = new Task("Task1");
 4    tskGen.Id = 1;
 5    tskGen.Uid = 1;
 6    tskGen.Start = DateTime.Parse("17-Aug-2009 8:00 AM" );
 7    tskGen.Finish = DateTime.Parse( "17-Aug-2009 5:00 PM" );
 8    project.RootTask = rootTask;
 9    project.RootTask.Children.Add(tskGen);
10    project.Save("Project.xml", SaveFileFormat.XML);

1    Dim project As New Project()
2    Dim tskGen As New Task("Task1")
3    tskGen.Id = 1
4    tskGen.Uid = 1
5    tskGen.Start = DateTime.Parse("17-Aug-2009 8:00 AM")
6    tskGen.Finish = DateTime.Parse("17-Aug-2009 5:00 PM")
7    project.RootTask = rootTask
8    project.RootTask.Children.Add(tskGen)
9    project.Save("Project.xml", SaveFileFormat.XML)

New Aspose.Tasks for .NET 8.x Approach

1    Project project = new Project();
2    Task task = project.RootTask.Children.Add("Task 1");
3    task.Set(Tsk.Start, project.RootTask.Get(Tsk.Start).AddDays(1));
4    // set task start day
5    project.Save("CreateTasks.xml", SaveFileFormat.XML);

1    Dim project As New Project()
2    Dim task As Task = project.RootTask.Children.Add("Task 1")
3    task.[Set](Tsk.Start, project.RootTask.[Get](Tsk.Start).AddDays(1))
4    'set task start day
5    project.Save("CreateTasks.xml", SaveFileFormat.XML)

Create and Add Resource to Project

Set and Get methods have been added to the Resource class of the API for manipulating attributes related to a project’s Resource.

Legacy API Code Sample

1    Project project = new Project();
2    Resource res =   Resource(new "Res1");
3    res.Id = 1;
4    res.Uid = 1;
5    res.Start = DateTime.Parse("19-Aug-2009 8:00 AM");
6    res.Finish = DateTime.Parse("19-Aug-2009 5:00 PM");
7    project.Resources.Add(res);
8    project.Save("Project.xml", SaveFileFormat.XML);

1    Dim project As New Project()
2    Dim res As New Resource("Res1")
3    res.Id = 1
4    res.Uid = 1
5    res.Start = DateTime.Parse("19-Aug-2009 8:00 AM")
6    res.Finish = DateTime.Parse("19-Aug-2009 5:00 PM")
7    project.Resources.Add(res)
8    project.Save("Project.xml", SaveFileFormat.XML)

New Aspose.Tasks for .NET 8.x Approach

1    Project project = new Project();
2    Resource rsc = project.Resources.Add("R1");
3    rsc.Set(Rsc.Start, DateTime.Parse("31-Aug-2014 8:00 AM"));
4    rsc.Set(Rsc.Finish, DateTime.Parse("31-Aug-2014 5:00 PM"));
5    project.Save("CreateResource.xml", SaveFileFormat.XML);

1    Dim project As New Project()
2    Dim rsc As Resource = project.Resources.Add("R1")
3    rsc.[Set](Rsc.Start, DateTime.Parse("31-Aug-2014 8:00 AM"))
4    rsc.[Set](Rsc.Finish, DateTime.Parse("31-Aug-2014 5:00 PM"))
5    project.Save("CreateResource.xml", SaveFileFormat.XML)

Create and Add Resource Assignment to Project

The ResourceAssignment class also introduces the Set and Get methods similar to other data collections of the API such as Tasks, Resources and Tasks Links.

Legacy API Code Sample

 1    Project project = new Project();
 2    Task tskRoot =  new Task();
 3    Task task = new Task("Task");
 4    Resource rsc = new Resource();
 5    rsc.StandardRate = 10;
 6    rsc.OvertimeRate = 15;
 7    ResourceAssignment assignment = new ResourceAssignment(task, rsc);
 8    assignment.Uid = 1;
 9    assignment.Start = DateTime.Parse("18-Aug-2009 8:00 AM" );
10    assignment.Finish = DateTime.Parse("18-Aug-2009 5:00 PM" );
11    project.RootTask = tskRoot;
12    project.RootTask.Children.Add(task);
13    project.Resources.Add(res);
14    project.ResourceAssignments.Add(assignment);
15    project.Save("project.xml", SaveFileFormat.XML);

 1    Dim project As New Project()
 2    Dim tskRoot As New Task()
 3    Dim task As New Task("Task")
 4    Dim rsc As New Resource()
 5    rsc.StandardRate = 10
 6    rsc.OvertimeRate = 15
 7    Dim assignment As New ResourceAssignment(task, rsc)
 8    assignment.Start = DateTime.Parse("18-Aug-2009 8:00 AM" )
 9    assignment.Finish = DateTime.Parse("18-Aug-2009 5:00 PM" )
10    assignment.Uid = 1
11    project.RootTask = tskRoot
12    project.RootTask.Children.Add(task)
13    project.Resources.Add(res)
14    project.ResourceAssignments.Add(assignment)
15    project.Save("project.xml", SaveFileFormat.XML)

New Aspose.Tasks for .NET 8.x Approach

1    Project project = new Project();
2    Task task = project.RootTask.Children.Add("Task");
3    Resource rsc = project.Resources.Add("Rsc");
4    rsc.Set(Rsc.StandardRate, 10);
5    rsc.Set(Rsc.OvertimeRate, 15);
6    ResourceAssignment assignment = project.ResourceAssignments.Add(task, rsc);
7    assignment.Set(Assn.Start,DateTime.Parse("18-Aug-2009 8:00 AM" ));
8    assignment.Set(Assn.Finish, DateTime.Parse("18-Aug-2009 5:00 PM" ));
9    project.Save("ResourceAssignments.xml", SaveFileFormat.XML);

1    Dim project As New Project()
2    Dim task As Task = project.RootTask.Children.Add("Task")
3    Dim rsc As Resource = project.Resources.Add("Rsc")
4    rsc.[Set](Rsc.StandardRate, 10)
5    rsc.[Set](Rsc.OvertimeRate, 15)
6    Dim assignment As ResourceAssignment = project.ResourceAssignments.Add(task, rsc)
7    assignment.Set(Assn.Start,DateTime.Parse("18-Aug-2009 8:00 AM"))
8    assignment.Set(Assn.Finish, DateTime.Parse("18-Aug-2009 5:00 PM" ) project.Save("ResourceAssignments.xml", SaveFileFormat.XML))

Conclusion

Migrating to Aspose.Tasks for .NET 8.0.0+ involves:

Replacing property-style assignments with the Set method.
Using constructors to create Task, Resource, and Calendar objects.
Adding these objects to the appropriate collections explicitly.
Removing obsolete API usage such as project.Tasks.Add() or project.Resources.NewResource().

By following these updated patterns, your project will be compatible with the latest version of Aspose.Tasks, benefiting from improved consistency and flexibility.
