Pass a struct from c++ to c# CLI

I have a C++ SDK where I'm passing information as a struct to a C# CLI wrapper.

The C++ struct is as follows:

typedef struct SDK_API tag_PDP_SystemInfo
{
    char siteName[MAX_TITLE_LENGTH + 1];
    UINT32 cameraCount;
    int sensorCount;
    int channelId;
    CameraInfo cameraInfo[MAX_CAMERA_COUNTS];
} NativeSystemInfo;

And my equivalent struct in my CLI code is:

[StructLayout(LayoutKind::Sequential, CharSet = CharSet::Ansi)]
public value struct SystemInfo
{
public:
    [MarshalAsAttribute(System::Runtime::InteropServices::UnmanagedType::ByValTStr, SizeConst = 32)] String^ SiteName;
    [MarshalAsAttribute(System::Runtime::InteropServices::UnmanagedType::U4)] UINT32 CameraCount;
    int SensorCount;
    int ChannelId;
    [MarshalAsAttribute(System::Runtime::InteropServices::UnmanagedType::ByValArray, ArraySubType = System::Runtime::InteropServices::UnmanagedType::LPStruct, SizeConst=36)] array<CameraInfo>^ CameraInfo;
};

Now my C++ code has a function that returns a struct like so:

NativeSystemInfo MySdk::GetSystemInfo()
{
    return m_systemInfo;
}

In my CLI code I am calling the C++ function like so:

SystemInfo MySDKCLI::GetSystemInfo()
{
    SystemInfo info;
    info = m_pMySdk->GetSystemInfo();   <--I get an Error in the '='

return info;
}

I get the following error in the equals sign:

nooperator= matches these operands 
operand types are MySDKCLIWrapper::SystemInfo=MySDKNative::NativeSystemInfo.

How do I pass the contents of the struct from the C++ to the CLI??
