.NET CORE 2 DLL引用带有C 代码运行时错误

.NET Core 2 DLL Reference With C++ Code Runtime Error

本文关键字：代码 运行时错误 引用 CORE DLL NET      更新时间：2023-10-16

小介绍：我正在从事一个.NET Core 2项目，并且需要第三方API，该API可用于C＃，但是当我检查(dotpeek(时，我发现他们使用C 用于某些功能。环境：vs 2017社区，.NET Core 2 x86，IIS Express

问题：当我添加参考并构建一个项目时，除了警告(黄色感叹号(之外，我不会遇到任何错误，但没有解释。当我向剩下的端点提出请求时，该端点使用了从上述.dll中获得的类。请注意，其他一切都很好。

我已经对此进行了很多搜索，但找不到任何适合我案子的解决方案。

tl; dr i将需要关于如何包含具有C 代码的.dll的某种解释，但主要是在C＃中写的。

谢谢Stackoverflow

.net core(尚未(支持C /CLI("托管C "(，并且将无法加载此类库。这是.NET Core 3.0的计划功能。
