所以我写了一个脚本来遍历和优化一些VHDX文件并输出结果。为了（显着）减少脚本运行时间，我自学了工作流程。这本身就是一次冒险，但我让脚本工作到输出结果的地步。调用变量并按保存百分比将其传递到排序对象中，然后按作业状态传递到排序对象中，然后传递到格式表中；代码实际上并没有对数据进行排序。它只是按添加到数组的顺序输出。

当它没有从工作流中提取数据时，代码运行良好（而是通过脚本串行运行）。我的假设是工作流将数据作为完整表输出到脚本数组，而不是单个条目，因此在到达脚本时没有任何要排序的内容（脚本将其视为单个条目） .

我仍在努力优化和清理代码，但我正试图让它首先工作。提前抱歉，可能有点难以阅读。

我期望将对象的输出输出到控制台；按状态排序和分组，因此该表仅显示两个或三个部分。我还应该从数组中收到一个未排序的数据 CSV，而是得到一个空的 CSV，其中一行表示“#TYPE Selected.System.Object[]”，一行包含列名。控制台输出如下所示：

   JobStatus: Failed (UPD likely in use!)
