我将 cimg（本机 c++ 头库）包装到 dot net 并对其进行了测试，它在 c++ CLR 中运行良好，我使用的数学方法看起来像这样。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++ 中使用了头文件，并将我的 win32 静态库添加到了附加库中（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，以便我能够在我的 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 App 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？如果您正在执行 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 ”）构建的。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。
