Question

我有一个面向64位平台的Win Forms应用程序（因为它使用64位Oracle.DataAccess库所以需要它。）

我在这个解决方案中添加了一个ASP.net表单应用程序，我想在ASP.net应用程序中添加对WinForms应用程序的引用。

我的WebApp也以64位为目标并正确构建，但是当我运行它时，我得到：

'无法加载文件或程序集“Oracle.DataAccess”或其中一个依赖项。

我还确保Oracle.DataAccess是新的64位版本。任何想法？
Winforms应用程序（引用了Oracle.DataAccess）运行100％，因此告诉我问题可能与dll版本不同。

有关以下错误的更多信息：

=== Pre-bind state information ===
LOG: User = Domain\myUser
LOG: DisplayName = Oracle.DataAccess

WRN: Partial binding information was supplied for an assembly:
WRN: Assembly Name: Oracle.DataAccess | Domain ID: 3
WRN: A partial bind occurs when only part of the assembly display name is provided.
WRN: This might result in the binder loading an incorrect assembly.
WRN: It is recommended to provide a fully specified textual identity for the assembly,
WRN: that consists of the simple name, version, culture, and public key token.

Answer 1

使用C：\ Windows \ Microsoft.NET \ Framework \ v4.0.30319 \ config \ machine.config
中的计算机配置文件

您的跟踪清楚地显示您的代码以32位模式运行。 64位程序从c：\ windows \ microsoft.net \ framework64目录加载machine.config文件。所以完全可以预料到BadImageFormatException。

您的项目无法在其运行的模式下进行配置，IIS中的应用程序池配置会选择位数。使用this web page中所示的高级设置进行配置。请确保您与正常配置机器的人交谈，此设置更改并非偶然。

Answer 2

如果您在使用IIS Express在Visual Studio（VS）中运行/调试Web应用程序时遇到此问题，请确保选中以下设置：

工具＆gt;选项＆gt;项目＆amp;解决方案＆gt; Web项目＆gt;将64位版本的IIS Express用于网站和项目

Answer 3

这可以通过从64-bit Oracle Data Access Components (ODAC) Downloads下载并执行'ODAC112030Xcopy.zip'中的install.bat文件来解决。
