运行 C++ 通过 NUnit 编写代码
我尝试使用 NUnit 来测试已经连接到 C++ 代码的 C# 代码（没有 NUnit，应用程序可以完美运行）。
在我的测试中，我通过 AppDomain.CurrentDomain.ExecuteAssembly(..) 运行 main 函数，但是当 C# 代码尝试与 C++“通信”时，它会引发异常并且测试崩溃。 例外是 System.Reflection.TargetInitationException 如果有人知道为什么会发生它将会非常非常有帮助......谢谢，Naama
I have tried to use NUnit to test C# code the is already connected to C++ code (without the NUnit the application work perfectly).
In my test I run the main function through AppDomain.CurrentDomain.ExecuteAssembly(..), However when the C# code tries to "communicate" with the C++ it throws an exception and the test crashes. The exception is System.Reflection.TargetInvocationException if anyone has and idea why its happen it will be very very helpful... Thanks, Naama

您的怀疑是正确的，它是在构造函数期间通过的，c# 中的构造函数正在尝试创建一个对象（它已经被包装并且在应用程序正常运行时完美工作），该对象是用 c++ 编写的，并且在 c++ 的构造函数中编写的对象抛出异常。
然而，该应用程序非常复杂，但如果需要澄清，我将编写一个代表真实应用程序的演示应用程序。
Your suspicions are correct it is being through during the constructor, the constructor in c# is trying to create an object (it is already wrapped and work perfect when the application is running normally) that is written in c++ and in c++ in the constructor of the object the exception is thrown.
However the application is very complex but if it necessary for clarification I will write a demo application that symbol the real one.
您的 C++ 代码中的类构造函数中可能会引发异常。 检查以确保您正确处理异常，并且向构造函数提供正确的信息，以便不会引发异常。
It is likely that an exception is being thrown in your C++ code, in the constructor of the class. Check to make sure you're handling exceptions properly and that you're giving the proper information to the constructor so exceptions aren't thrown.
