推荐答案

我有一个问题，是什么需要从BAL类添加对DAL类的引用。因为DLL引用将bi添加到BLL引用，BLL引用将是添加到Presentation层。但是你仍然可以添加BLL引用到DLL类。只需将所有类拉到一个文件夹并将该文件夹放到你的应用程序的App_Code文件夹然后你可以访问所有的类。如果它不起作用请请告诉我。

Hi,
I have a question that what is the need of adding reference to the DAL class from BAL classes.Because DLL reference will bi added to BLL reference and BLL references will be added to Presentation layer.But still you can add the BLL references to the DLL classes.Just pull all classes to a folder and put that folder to App_Code folder of your application then you can access to all the classes.If it does not works please let me know.
