SWIG C#对象向量异常

我在C++中有一个自定义异常，它将MyCustomClass对象的std:：vector作为参数

我正在使用swig将我的C++项目转换为C#。要处理C++和C#之间的异常，需要编写一些填充代码：

%insert(runtime) %{
  // Code to handle throwing of C# CustomApplicationException from C/C++ code.
  // The equivalent delegate to the callback, CSharpExceptionCallback_t, is CustomExceptionDelegate
  // and the equivalent customExceptionCallback instance is customDelegate
  typedef void (SWIGSTDCALL* CSharpExceptionCallback_t)(const char *);
  CSharpExceptionCallback_t customExceptionCallback = NULL;

  extern "C" SWIGEXPORT
  void SWIGSTDCALL CustomExceptionRegisterCallback(CSharpExceptionCallback_t customCallback) {
    customExceptionCallback = customCallback;
  }

  // Note that SWIG detects any method calls named starting with
  // SWIG_CSharpSetPendingException for warning 845
  static void SWIG_CSharpSetPendingExceptionCustom(const char *msg) {
    customExceptionCallback(msg);
  }
%}

%pragma(csharp) imclasscode=%{
  class CustomExceptionHelper {
    // C# delegate for the C/C++ customExceptionCallback
    public delegate void CustomExceptionDelegate(string message);
    static CustomExceptionDelegate customDelegate =
                                   new CustomExceptionDelegate(SetPendingCustomException);

    [global::System.Runtime.InteropServices.DllImport("$dllimport", EntryPoint="CustomExceptionRegisterCallback")]
    public static extern
           void CustomExceptionRegisterCallback(CustomExceptionDelegate customCallback);

    static void SetPendingCustomException(string message) {
      SWIGPendingException.Set(new CustomApplicationException(message));
    }

    static CustomExceptionHelper() {
      CustomExceptionRegisterCallback(customDelegate);
    }
  }
  static CustomExceptionHelper exceptionHelper = new CustomExceptionHelper();
%}

与自定义C#异常一起：

// Custom C# Exception
class CustomApplicationException : global::System.ApplicationException {
  public CustomApplicationException(string message) 
    : base(message) {
  }
}

和SWIG接口代码：

%typemap(throws, canthrow=1) std::out_of_range {
  SWIG_CSharpSetPendingExceptionCustom($1.what());
  return $null;
}

%inline %{
void oddsonly(int input) throw (std::out_of_range) {
  if (input%2 != 1)
    throw std::out_of_range("number is not odd");
}
%}

这适用于基本异常（示例将字符串作为参数），但是现在我试图传递对象的向量，我遇到了麻烦。我尝试过使用编组，但我不清楚它是如何工作的，或者在这种情况下我是否应该尝试使用编组

有没有人这样做过，或者类似的事情
