Shows how to work with list util Find method.

public void WorkWithListUtilsFind()
    var project = new Project(DataDir + "Project2003.mpp");
    List<Filter> taskFilters = project.TaskFilters.ToList();

    Assert.AreEqual(3, taskFilters.Count, "Project.TaskFilters count");

    var filter = ListUtils.Find(taskFilters, new FilterByName("&All Tasks"));

    Console.WriteLine("Name: " + filter.Name);
    Console.WriteLine("Filter Type: " + filter.FilterType);
    Console.WriteLine("Show In Menu: " + filter.ShowInMenu);
    Console.WriteLine("Show Related Summary Rows: " + filter.ShowRelatedSummaryRows);

public class FilterByName : ICondition<Filter>
    private readonly string name;

    public FilterByName(string name)
    { = name;

    /// <summary>
    /// Returns true if the specified object satisfy the conditions.
    /// </summary>
    /// <param name="el">The object to check.</param>
    /// <returns>True if the object satisfy the conditions.</returns>
    /// <inheritdoc />
    public bool Check(Filter el)
        return el.Name ==;
