从ASP.NET使用本机DLL时出现BadImageFormatException 我在ASP.NET应用程序中引用了一个托管C++项目，它使用了名为“LIbMMD .DLL”的本地DLL。如果我用visual studio运行ASP.NET应用程序，我会得到一个BadImageFormatException，它告诉我“模块应该包含程序集清单”（翻译自德语）

将本机DLL包含到asp.net项目中的首选方式是什么？要在哪个目录中搜索文件？在路径“C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\临时ASP.NET文件”中，似乎只有托管程序集，而不是本机DLL

确保ASP.NET应用程序的位（由IIS应用程序池设置）与本机dll的位匹配。例如，32位进程无法加载64位dll

我的电脑是32位的，也都是DLL。当我将dll放入应用程序文件夹时，该库在windows窗体应用程序中工作。但是在ASP.NET中，我不知道将dll放在哪个文件夹中

将dll放入正确位置的最简单方法是让VS/ASP.NET通过以下任一方式进行：

• 在项目参考上，将“复制本地”参数设置为true
• 使用“无”生成操作将dll添加到项目中，并复制到目标文件夹
• 将dll添加到项目的

  bin

  文件夹中

---

我将从最后一个选项开始，但还要检查以查看Windows尝试从何处加载dll（即加载路径中包含哪些web应用文件夹）。本机程序集和托管程序集之间的交互可能有点困难（由于加载程序搜索规则不同），ASP.NET随后会添加其自身的差异，这些差异在一定程度上适用于本机dll。

请确保ASP.NET应用程序的位（由IIS应用程序池设置）与本机dll的位匹配。例如，32位进程无法加载64位dll
