Could not load file or assembly 'HDY.BLL' or one of its dependencies. 系统找不到指定的文件。...

错误提示:

模仿petshop 4,我的程序是这样的,有

project            class              作用

=================================

DBUtility------SQLhelper.cs (主要是sql的基本操作)

Model---------UserInfo.cs  (用户的基本信息)

IDAL-----------IUser.cs       (用户操作--添加新用户、修改用户信息、等---接口)

DAL------------User.cs        (实现IUser的操作)

DALFactory---DataAccess.cs(工厂类创建User类)

IBLL------------IUser.cs      (和IDAL中的IUser差不多)

BLL-------------User.cs        (和DAL中的User差不多,功能更具体)

BLLFactory----DataAccess.cs(工厂类和DALFactory中DataAccess差不多)

在default.aspx.cs中利用BLLFactory.DataAccess.CreateUser创建一个类出现错误:

================================================================

Exception Details: System.IO.FileNotFoundException: Could not load file or assembly 'HDY.BLL' or one of its dependencies. 系统找不到指定的文件。

Source Error:


Source File: D:\华东院网站\HDY\BLLFactory\DataAccess.cs    Line: 22

Assembly Load Trace: The following information can be helpful to determine why the assembly 'HDY.BLL' could not be loaded.


Stack Trace:



Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.210

===================================================================

问题在于:
DALFactory中的DataAccess类中反射应用的HDY.DAL应改为DAL,因为在web/bin中的dll为DAL.dll。
BLLFactory中的也一样。
