c# - CLI/C#将std::vector <>结构数据传递给C#

我在C++中有以下内容

class TrimInfo
{
public:
    std::string LineName;
    std::string OrigImagePath;
    double Width;
    double Height;
};

typedef std::shared_ptr<TrimInfo> TrimInfoPtr;

void SomeFunction();

bool DoSomethingElse(std::vector<JunkInfoPtr> &junkinfo, int *count);

bool SetTrimInfo(std::string ModelName, std::string PieceName, std::vector<TrimInfoPtr> trimInfo);

在我拥有的C#代码中

namespace BatchMergeAPI
{
    public partial class BatchMergeInterface
    {
    public struct TrimInformation
    {
        public string LineName;
        public string OrigImagePath;
        public double Width;
        public double Height;
    };

    public bool SetTrimInfo(string ModelName, string PieceName, List<TrimInformation> trimInfo)
    {

       return true;
    }
   }
}

现在回到c++代码中，将信息传递给C#，我这样做了，但是在til-> Add(ti)上看到了错误，



我了解错误，但不确定如何纠正。

bool BatchMergeWrapper::SetTrimInfo(std::string modelName, std::string pieceName, std::vector<TrimInfoPtr> trimInfo)
{
System::String^ mn = gcnew System::String(modelName.c_str());
System::String^ pn = gcnew System::String(pieceName.c_str());

List<BatchMergeInterface::TrimInformation> ^til = gcnew List<BatchMergeInterface::TrimInformation>();

for (unsigned i = 0; i < trimInfo.size(); ++i)
{
    BatchMergeInterface::TrimInformation^ ti = gcnew BatchMergeInterface::TrimInformation();

    ti->Height = trimInfo[i]->Height;
    ti->Width = trimInfo[i]->Width;
    ti->LineName = gcnew System::String(trimInfo[i]->LineName.c_str());
    ti->OrigImagePath = gcnew System::String(trimInfo[i]->OrigImagePath.c_str());

    til->Add(ti);
}

return  _private->batchmergeAPI->SetTrimInfo(mn, pn, til);
}

感谢您的任何帮助，我不得不看所有List示例。

最佳答案

您缺少两个^:

List<BatchMergeInterface::TrimInformation^> ^til = gcnew List<BatchMergeInterface::TrimInformation^>();
