如何在C#中将指定JSON对象转换为目标格式的新JSON对象

可以通过遍历原始数据数组，逐步构建目标层级结构的对象，以下是具体实现代码：

JavaScript 实现代码 #

var data1 = [{"TheatreName":"AMEA","Country":"CANADA","Riskcount":50},{"TheatreName":"AMEA","Country":"UK","Riskcount":30},{"TheatreName":"AMER","Country":"Japan","Riskcount":80},{"TheatreName":"AMER","Country":"US","Riskcount":90},{"TheatreName":"APAC","Country":"Bangladesh","Riskcount":4},{"TheatreName":"APAC","Country":"Hong Kong","Riskcount":12},{"TheatreName":"APAC","Country":"India","Riskcount":126}];

var data = {};

// 遍历原始数组，构建目标结构
data1.forEach(item => {
  // 若当前大区未在目标对象中，先初始化空对象
  if (!data[item.TheatreName]) {
    data[item.TheatreName] = {};
  }
  // 将国家与风险数的键值对存入对应大区对象
  data[item.TheatreName][item.Country] = item.Riskcount;
});

console.log(data);

最终输出结构 #

执行代码后，data 将生成符合需求的层级结构：

var data = {
  "AMEA": {
    "CANADA": 50,
    "UK": 30
  },
  "AMER": {
    "Japan": 80,
    "US": 90
  },
  "APAC": {
    "Bangladesh": 4,
    "Hong Kong": 12,
    "India": 126
  }
}
