我正在开发一个调用DB2数据库的ASP.NET网站。我在Windows 2008服务器上安装了Visual Studio，该站点将在此处托管。当我使用集成的Web服务器在Visual Studio中调试站点时，我可以连接到数据库并成功运行站点。但是，在同一台服务器上设置站点在IIS7中时，由于以下错误，我无法访问站点或数据库。
以下是技术细节：
Windows 2008 Server
IIS 7
Visual Studio 2010 Premium
DB2 v9.5.301.436
Could not load file or assembly 'IBM.Data.DB2' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.BadImageFormatException: Could not load file or assembly 'IBM.Data.DB2' or one of its dependencies. An attempt was made to load a program with an incorrect format.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.
Assembly Load Trace: The following information can be helpful to determine why the assembly 'IBM.Data.DB2' could not be loaded.
WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

我不明白为什么网站在使用Visual Studio Web服务器时可以正常运行，但在IIS中无法工作。我不知道这是一个IIS问题还是我正在使用的IMB.Data.DB2.dll版本的问题。如果有人有解决方案或任何想法，将不胜感激。
谢谢。
