c++ - Visual Studio 2012 中的 BadImageFormatExeption

Question

我将 cimg( native c++ 头库)包装到 dot net，我测试了它，它在 c++ CLR 中运行良好，我使用的方法如下所示。 因为 cimg 只是一个头文件，所以我创建了一个 win32 静态库项目并构建了它 然后我在 CLR c++ 中使用了 header ，并在附加库中添加了我的 win32 静态库 (我这样做的原因是为了避免链接器错误)，并且它工作正常最后我尝试从 CLR 制作一个 DLL，这样我就可以在我的 c# GUI 项目中使用它 所以我将 CLR c++ 项目的输出更改为 DLL，然后我在 c# winform 应用程序中引用它，然后当我尝试运行它时，我收到此错误消息。

您的 DLL 和应用程序的“位数”是否可能不匹配？如果您正在进行 32 位构建，请确保 C++/CLI 包装器 .DLL 和 WinForms C# GUI .EXE 都是使用平台目标 x86(而不是“任何 CPU”)。要检查这一点，在 VS2010 中，您可以转到项目属性，然后选择“构建”选项卡。
