    // gather all project tasks
    var coll = new ChildTasksCollector();
    TaskUtils.Apply(project.RootTask, coll, 0);

    // create a filter condition
    var filter = new NullCondition();

    // and reverse it by applying <see cref="Aspose.Tasks.Util.Not`1" /> condition
    var condition = new Not<Task>(filter);

    // apply the condition to the collected tasks
    List<Task> collection = Filter(coll.Tasks, condition);
    foreach (var task in collection)
    {
        Console.WriteLine("Name: " + task.Get(Tsk.Name));

        // work with other properties...
    }

    // ...
}

private static List<T> Filter<T>(IEnumerable<T> array, ICondition<T> cond)
{
    var result = new List<T>();

    foreach (var item in array)
    {
        if (cond.Check(item))
