寻savefiledialog的例子(c#)?
我的代码如下： autodesk.autocad.windows.savefiledialog sfd = new autodesk.autocad.windows.savefiledialog("文件另存为","drawing1.dwg","dwg","图形存储",autow.savefiledialog.savefiledialogflags.defaultisfolder); if(sfd.showdialog() == dialogresult.ok) db.saveas(sfd.filename,dwgversion.current); 但是会跳出异常，哪位有这方面的例子，多
