与任务连接的MPXJ自定义字段

大家早上好，

有人知道如何使用MPXJ v5.1.5有效地读取MPP吗?项目文件以获取链接到其分配的任务的大纲代码值。

我已经找到了获得任务和时间尺度数据的方法，但我如何找出什么大纲代码或自定义字段链接到任何任务?这将有助于创建关于这些自定义字段的运行情况的报告。

这是我的主要代码片段，用于检索任务及其时间尺度数据。这段代码在后台工作线程上运行，并报告进度。

    void Work_DoWork(object sender, DoWorkEventArgs e)

            try

                MPXJ.ProjectFile mpx = reader.read(Document_Selected_Details.FileName);
                int count = mpx.AllTasks.Size();
                int stepsize = 100002 / count;
