在VB里的连接CAD函数怎么移植到C#下啊？万分感谢 Sub 连接AutoCAD()         On Error Resume Next         Acadapp = GetObject(, "AutoCAD.Application")         If Err.Number Then             Err.Clear()             Acadapp = CreateObject("AutoCAD.Application")             If Err.Number Then                 MsgBox("不能运行AutoCAD,请检查是否安装了AutoCAD 2004")                 Exit Sub             End If         End If         Acadapp.Visible = True '界面可视         AcadApp.WindowState = autocad.AcWindowState.acMax '界面最大化         AppActivate(Acadapp.Caption) '显示AutoCAD界面     End Sub
