Asp.net 目标平台和'；无法加载文件或程序集'；错误

我有一个针对64位平台的Win Forms应用程序（它是必需的，因为它使用64位

Oracle.DataAccess

库）

我已将ASP.net表单应用程序添加到此解决方案中，我想将WinForms应用程序的引用添加到ASP.net应用程序中

我的WebApp也以64位为目标并正确构建，但当我运行它时，我得到：

“无法加载文件或程序集”

Oracle.DataAccess

“或其依赖项之一”

我还确保Oracle.DataAccess是新的64位版本。 有什么想法吗？
Winforms应用程序（引用了Oracle.DataAccess）正在100%运行，这说明问题可能不在dll版本上

有关错误的详细信息如下：

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

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正在32位模式下运行。64位程序从c:\windows\microsoft.net\framework64目录加载machine.config文件。因此，BadImageFormatException是完全可以预料的

---

它不是由您的项目来配置在什么模式下运行，而是由IIS中的应用程序池配置来选择位。使用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，此设置更改不是意外事件。

这可以通过从下载并执行“odac11230xcopy.zip”中的install.bat文件来解决

如果在Visual Studio（VS）中使用IIS Express运行/调试web应用时遇到此问题，请确保选中以下设置：

---

工具>选项>项目和解决方案>Web项目>将64位版本的IIS Express用于网站和项目

是否检查了Oracle.DataAccess dll上的引用？也许您的应用程序试图从另一个只有x86版本的地方加载它。此外，请确认在构建平台设置为x64时，所有项目的项目属性->构建->平台目标均为x64。请检查两个应用程序的项目属性中的目标框架，并确保它们匹配。默认情况下，WinForms将以“.NET Framework 4客户端配置文件”为目标，而不是“.NET Framework 4”。我仔细检查了这两个项目是否在x64上。我重新下载了Oracle.DataAccess 64位dll，并确保引用了该dll。您是否已将Oracle.DataAccess dll的副本放入项目的bin文件夹中？这就是它试图加载它的地方。Visual Studio不会将dll从引用位置复制到bin文件夹。你必须手动操作。是的，我也这么做了-谢谢。谢谢-在设计期间是否有可能在我的开发机器上更改此设置（即尚未部署到IIS上）？第一次谷歌点击：我也看到了，但事实上，它声明它未经完全测试，这让我担心。我确实试过了，但还是没有成功。我还尝试在启用了32位的IIS上进行部署，但仍然存在此错误。然而，我认为某些东西确实起了作用，因为错误消息看起来有些不同。因此，我将接受你的回答。谢谢
