正如您在这里看到的，它是一个有四个状态的状态机：CONVERSOR、OPEN、PLOTTOPDF和CLOSE。我读取磁盘中的N个文件，并在状态中保持循环，直到没有要处理的mroe文件为止。我希望所有的dxfs文件都能转换成pdf。当我只为一个文件运行这个程序时，它可以正常工作。问题是：
想象一下，我在第一个文件中经过CONVERSOR->OPEN->PLOTTOPDF->CLOSE。AutoCAD打开文件，切换活动文档，我无法进入关闭状态，然后我的机器状态停止在PLOTTOPDF状态。(即使是第一个文件也没有关闭，而是正确地转换为pdf(。有人能帮忙吗？我认为问题在于，当我打开一个新文件时，激活的文档会发生更改，AutoCAD在查看命令是否完成时会迷失方向。
布局必须是最新的才能打印。所以你必须打电话给：
Application.DocumentManager.MdiActiveDocument = doc;
LayoutManager.Current.CurrentLayout = layoutName;
否则，方法CreateLayout的名称是错误的。你不是在创建一个布局，你只是得到了它。
我不明白你为什么要使用COM来获取文档的名称。
AcadDocument ppp = (AcadDocument)doc.GetAcadDocument();
String nome_arq = ppp.Name;
nome_arq = nome_arq.Remove(nome_arq.Length - 4, 4);
可替换为：
nome_arq = System.IO.Path.GetFileNameWithoutExtension(doc.Name);
