c++-cli - 从 JSON 文件 c/cli 获取字符串

Question

我有一个 json 文件，我需要解析它并从中获取一些字符串，托管 C++ (c++/cli) 中是否有任何代码或示例，谢谢。 这是我的 json 文件的摘录，我需要获取所有节点

{ "ID": "{15DFD536-EC23-4624-803E-5AA719DC7A85}", "节点": [ -0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0, -0.01, 0.01 ]}

Answer 1

这是使用 Json.NET 的示例:

#include "stdafx.h"

using namespace System;
using namespace Newtonsoft::Json;

ref class MyData
{
    public: Guid ID;
    public: array<double>^ Nodes;
};

int main(array<System::String ^> ^args)
{
    String^ json = "{ \"ID\": \"{15DFD536-EC23-4624-803E-5AA719DC7A85}\", \"Nodes\": [ -0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0.01, 0, -0.01, 0.01 ]}";

    MyData^ data = JsonConvert::DeserializeObject<MyData^>(json);

    Console::WriteLine("ID: {0}\nNodes: {1}", data->ID, String::Join(",", System::Linq::Enumerable::Cast<Object^>(data->Nodes)));

    return 0;
}

结果:

ID: 15dfd536-ec23-4624-803e-5aa719dc7a85
Nodes: -0.01,0.01,0.01,0.01,0.01,0.01,0.01,0.01,0,-0.01,0.01
