[英]CLR namespace does not exist
I have a C# project with 2 function 我有一个带有2个功能的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);
}
}
}
same for SaturationLevelData 对于SaturationLevelData相同
I created a c++\\CLI project and I want to give the two class into a function as parameters 我创建了一个c ++ \\ CLI项目,我想将两个类作为参数提供给函数
#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 标头
#include "PreprocessorWrapper.h"
void ToolBox::PreprocessorWrapper::Function1(BlackLevelData^ blackLevelData, SaturationLevelData^ saturationLevelData)
{
_preprocessor->Function1();
}
ToolBox::PreprocessorWrapper::PreprocessorWrapper()
{
_preprocessor = new Preprocessor();
}
here are the errors I get 这是我得到的错误

Can you see what I did wrong here? 你能看到我在这里做错了吗?
yes I have added the C# project as reference 是的,我已经添加了C#项目作为参考
First, make sure you are building your C++ project with the /clr switch. 首先,请确保使用/ clr开关构建C ++项目。 It is strange you are not referencing at least the System assembly. 奇怪的是,您至少没有引用系统程序集。
Second, the screenshot you provided seems to indicate that your C++/CLI project is using the .NET Framework v4.0. 其次,您提供的屏幕快照似乎表明您的C ++ / CLI项目正在使用.NET Framework v4.0。 Assuming your C# project is using the .NET Framework v4.5, try updating your C++/CLI project to match. 假设您的C#项目正在使用.NET Framework v4.5,请尝试更新您的C ++ / CLI项目以使其匹配。 You can hand-edit the project file (.vcxproj) as follows: 您可以按如下方式手动编辑项目文件(.vcxproj):
<PropertyGroup Label="Globals">
<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
</PropertyGroup>
I reproduced your issue by changing the version to v4.0 with Visual Studio 2013. 我通过将Visual Studio 2013版本更改为v4.0来重现您的问题。
