我有一个 c++ 项目，它将调用一个 C# 函数，之后，c# 将调用一个 c++ 函数（两者都有返回值）。我卡在stackoverflow上有人给我的COM接口上（我对c++或c#没有太多经验，只有java），但由于某种原因，当我尝试编译C++代码时它给了我一个错误，致命错误C1196 : 'FaceTrackingBasics-WPF' : 在类型库 c:\FaceTrackingBasics-WPF/bin/x86/Debug/FaceTrackingBasics-WPF.tlb 中找到的标识符不是有效的 C++ 标识符。

你能发现一些错误吗？也许我不应该在一个文件中有两个类？顺便说一句，c# 代码与一个窗口相关联，我不知道它是否会导致问题。谢谢

'FaceTrackingBasics-WPF' : ... is not a valid C++ identifier

It is not, a C++ identifier cannot contain a dash, "-". Just like C# btw. This name came from your project name. Which set the type library name. Which set the name of the namespace that the #import directive created.

Several possible workarounds beyond simply renaming your project. You can apply attributes to the #import directive. Like "auto-rename", "no-namespace" and "rename-namespace":

   #import "FaceTrackingBasics-WPF.tlb" rename_namespace("managed")
   using namespace managed;
