ASP.NET – IIS7 – IBM DB2问题

我在一个调用DB2数据库的ASP.NET网站上工作.我将Visual Studio安装在 Windows 2008服务器上,该站点将被托管.当我在Visual Studio中调试站点时,使用集成的Web服务器,我可以连接到数据库,站点运行正常.当我将IIS7中的站点设置在同一个服务器上时,由于出现以下错误,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 [HKLMSoftwareMicrosoftFusion!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 [HKLMSoftwareMicrosoftFusion!EnableLog].

我不明白网站如何使用Visual Studio Web服务器运行良好,而不能在IIS中运行.我不知道这是否是IIS问题,或者是我正在使用的IMB.Data.DB2.dll的版本.如果有任何人有解决方案或任何想法,他们将不胜感激.

谢谢.
