JsonConvert::DeserializeObject erro c++ cli

Question

我正在尝试打开一个文件，.json已经将其发送到一个类。但是我在做的时候会出错。

ref class CutAnnotationJSon
{
public:
    int index;
    String^ nomeTipo;
    double pontoX1;
    double pontoY1;
    double pontoX2;
    double pontoY2;

    double height;

    int r;
    int g;
    int b;

    int numberCut;
};
ref class PanoramicAnnotationJSon
{
public:
    int index;
    String^ nomeTipo;
    double pontoX1;
    double pontoY1;
    double pontoX2;
    double pontoY2;
    int r;
    int g;
    int b;
};
ref class DadosJSon
{
public:
    List<PanoramicAnnotationJSon^>^ panoramicAnnotation = gcnew List<PanoramicAnnotationJSon^>;
    List<CutAnnotationJSon^>^ cutAnnotation = gcnew List<CutAnnotationJSon^>;
};

用

DadosJSon^ dadosJSon = JsonConvert::DeserializeObject<DadosJSon^>(File::ReadAllText("c:/movie.json"));

错误信息：

103  IntelliSense: more than one instance of overloaded function "Newtonsoft::Json::JsonConvert::DeserializeObject" matches the argument list:
        function template "T Newtonsoft::Json::JsonConvert::DeserializeObject<T>(System::String ^value)"
        function template "T Newtonsoft::Json::JsonConvert::DeserializeObject<T>(System::String ^value, ... cli::array<Newtonsoft::Json::JsonConverter ^, 1> ^converters)"
        argument types are: (System::String ^)  

我正在使用Newtonsoft::Json::;

我无法重现该问题。 但是，您可以通过以下方式显式选择JsonConvert.DeserializeObject(String, JsonSerializerSettings)重载（它执行您想要的操作）：

DadosJSon^ dadosJSon = JsonConvert::DeserializeObject<DadosJSon^>(File::ReadAllText("c:/movie.json"), (JsonSerializerSettings ^)nullptr);

传递设置的nullptr值等效于 JsonConvert::DeserializeObject<DadosJSon^>(File::ReadAllText("c:/movie.json")) 。
