Marshal.GetActiveObject("AutoCAD.Application.16") 问题

caolijun0359

IAcadApplication CADApp = System.Runtime.InteropServices.Marshal.GetActiveObject("AutoCAD.Application.16") as IAcadApplication; 方法为什么总是不能获取到已经打开的CAD Application对象呢，权限问题吗 还是什么问题，如果是权限问题的话 IAcadApplication CADApp = new AcadApplicationClass();却是可以的。期盼高手解决
