public bool IsReadOnly { get; }Property Value

Methods
Add(Task)
Add the specified task to the instance of the Aspose.Tasks.TaskCollection class. If ParentProject.CalculationMode is None user should invoke Project.Recalculate() after using this method (It will reschedule all project tasks (start/finish dates, sets early/late dates) and calculate the dependent fields such as slacks, work and cost fields, ids and outline levels). If ParentProject.CalculationMode is Manual the method will calculate only task id, outline level and outline numbers automatically. If ParentProject.CalculationMode is Automatic the method reschedules all project’s tasks automatically (start/finish dates, sets early/late dates, calculates slacks, work and cost fields, recalculates ids and outline levels).
public void Add(Task item)Parameters
item Task
the specified task which should be added to this task collection.
Add()
Adds new task to project tasks collection on the same outline level of the last task.
public Task Add()Returns
returns the newly added instance of the Aspose.Tasks.Task class.
Add(string)
Adds a new task to children tasks collection.
public Task Add(string taskName)Parameters
taskName string
the specified task name.
Returns
returns the newly added instance of the Aspose.Tasks.Task class.
Add(string, int)
Adds a new recurring task to children tasks collection.
public Task Add(string taskName, int beforeTaskId)Parameters
taskName string
the specified task name.
beforeTaskId int
The specified id of a task before which a new task will be inserted.
Returns
returns a task which was inserted before a task with the specified id.
Exceptions
ArgumentOutOfRangeException is thrown if the specified id is not a valid task id.
Add(RecurringTaskParameters)
Inserts a new task before a task with the specified id and on the same outline level.
public Task Add(RecurringTaskParameters parameters)Parameters
parameters RecurringTaskParameters
The parameters the specified parameters for creation of recurring task.
Returns
returns the newly added instance of the Aspose.Tasks.Task class.
Exceptions
Thrown if the specified parameters are null.
Thrown if the specified parameters are invalid.
Contains(Task)
Checks if collection contains specified item.
public bool Contains(Task item)Parameters
item Task
The item to check.
Returns
true, if collection contains an item, false otherwise.
GetById(int)
Returns a task with the specified Id whose ancestor is parent task of this collection .
public Task GetById(int id)Parameters
id int
TaskEntity Id
Returns
returns the instance of Aspose.Tasks.Task class with the specified id whose ancestor is parent task of this collection.
GetByUid(int)
Returns a task with the specified Uid whose ancestor is parent task of this collection .
public Task GetByUid(int uid)Parameters
uid int
TaskEntity Uid.
Returns
returns the instance of Aspose.Tasks.Task class with the specified uid whose ancestor is parent task of this collection.
GetEnumerator()
Returns an enumerator for this collection.
public IEnumerator<task> GetEnumerator()Returns
IEnumerator<Task>
an enumerator for this collection.
Insert(int, Task)
This is the stub implementation of IList’s Insert method, that only throws NotSupportedException
public void Insert(int index, Task item)Parameters
index int
The index to insert at.
item Task
The item to insert.
Remove(Task)
This is the stub implementation of ICollection’s Remove method, that only throws NotSupportedException
public bool Remove(Task item)Parameters
item Task
The item to remove.
Returns
true if the item was removed; false otherwise.
ToList()
Converts the TaskCollection object to a list of Aspose.Tasks.Task objects.
public List<task> ToList()Returns
returns a list which contains the Aspose.Tasks.Task class instances of this collection. </task></task></task>
