CLR 命名空间不存在

Question

我有一个包含 2 个函数的 C# 项目

namespace LibiqCommonStructures 
{
  public class BlackLevelData : List<BlackLevelLookupTable>
  {
      public BlackLevelData()
      {
      }

       public BlackLevelData(BlackLevelData original)
          : base(original.DeepCopy())
      {
      }

       public void AddLookupTable(double gain, double exposure, double[] levels)
      {
          var table = new BlackLevelLookupTable
          {
              AnalogGain = gain,
              ExposureTime = exposure,
             ChannelLevels = levels
          };

          Add(table);
      }
  }
}

SaturationLevelData 相同

我创建了一个c++\CLI项目，我想把这两个class作为参数传给一个函数

#pragma once
#include "Preprocessor.h"


using namespace LibiqCommonStructures;

namespace ToolBox {

    public ref class PreprocessorWrapper
    {
    public:        
        PreprocessorWrapper();        
        void Function1(BlackLevelData^ blackLevelData, SaturationLevelData^ saturationLevelData);
    private:
        Preprocessor* _preprocessor;
    };
}

header

 #include "PreprocessorWrapper.h"


void ToolBox::PreprocessorWrapper::Function1(BlackLevelData^ blackLevelData, SaturationLevelData^ saturationLevelData)
{    
    _preprocessor->Function1();
}

ToolBox::PreprocessorWrapper::PreprocessorWrapper()
{
    _preprocessor = new Preprocessor();
}

这是我得到的错误

你能看出我哪里做错了吗？

是的，我添加了 C# 项目作为参考

Answer 1

首先，确保您正在使用 /clr 开关构建 C++ 项目。很奇怪你至少没有引用系统程序集。

其次，您提供的屏幕截图似乎表明您的 C++/CLI 项目正在使用 .NET Framework v4.0。假设您的 C# 项目正在使用 .NET Framework v4.5，请尝试更新您的 C++/CLI 项目以匹配。您可以手动编辑项目文件 (.vcxproj)，如下所示：

<PropertyGroup Label="Globals">
    <TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
</PropertyGroup>

我通过将版本更改为 v4.0 Visual Studio 2013 来重现您的问题。
