public void PreAlg(Task el, int level)
ParameterTypeDescription
elTaskParent task.
levelInt32Tree node level.

Examples

Shows how to use <see cref=“Aspose.Tasks.Util.RemoveTask” /> tree based algorithm.

public void WorkWithRemoveTask()
{
    var project = new Project(DataDir + "Project1.mpp");
    var task1 = project.RootTask.Children.Add("1");
    var task2 = project.RootTask.Children.Add("2");
    var task3 = project.RootTask.Children.Add("3");
    var task4 = project.RootTask.Children.Add("4");

    List<Task> tasks = new List<Task>(project.RootTask.SelectAllChildTasks());
    Console.WriteLine("Number of tasks before using the algorithm: " + tasks.Count);
    foreach (var task in project.RootTask.SelectAllChildTasks())
    {
        Console.WriteLine("Task Name: " + task.Get(Tsk.Name));
    }

    Console.WriteLine();

    // use tree based algorithm to delete task1 from the tree
    var algorithm = new RemoveTask(task1);

    // apply the algorithm to the task tree
    TaskUtils.Apply(project.RootTask, algorithm, 0);

    // check the results
    tasks = new List<Task>(project.RootTask.SelectAllChildTasks());
    Console.WriteLine("Number of tasks after using the algorithm: " + tasks.Count);
    foreach (var task in project.RootTask.SelectAllChildTasks())
    {
        Console.WriteLine("Task Name: " + task.Get(Tsk.Name));
    }

    // ...
}
