如何向现有项目添加问题跟踪器（包、功能、支持）？

请帮忙解决

    [enter image description here][1]var project = manager.GetObject(project_id, null);
    project.Description = "Updated description";
    ProjectIssueCategory proCat = new ProjectIssueCategory();
    proCat.Id = 10;
    proCat.Name = "Feature";
    project.IssueCategories = new List();
    project.IssueCategories.Add(proCat);
    project.Trackers = new List();

    project.Trackers.Add(new ProjectTracker(){Name = "Bag"});
    manager.UpdateObject(project_id, project);
    var updatedProject = manager.GetObject<Project>(project_id, null);
    Console.WriteLine("Updated issue: {0}.", updatedProject);
