如何使用 C# 创建复杂的 JSON 对象

我有这样的 JSON 结构：

{
 "name": "flare",
 "children": [
  {
   "name": "analytics",
   "children": [
    {
     "name": "cluster",
     "children": [
      {"name": "AgglomerativeCluster", "size": 3938},
      {"name": "MergeEdge", "size": 743}
     ]
    },
    {
     "name": "graph",
     "children": [
      {"name": "BetweennessCentrality", "size": 3534},
      {"name": "SpanningTree", "size": 3416}
     ]
    },
    {
     "name": "optimization",
     "children": [
      {"name": "AspectRatioBanker", "size": 7074}
     ]
    }
   ]
  },
  {
   "name": "animate",
   "children": [
    {"name": "Easing", "size": 17010},
    {"name": "FunctionSequence", "size": 5842},
    {
     "name": "interpolate",
     "children": [
      {"name": "ArrayInterpolator", "size": 1983},
      {"name": "RectangleInterpolator", "size": 2042}
     ]
    },
    {"name": "ISchedulable", "size": 1041},
    {"name": "Tween", "size": 6006}
   ]
  }
 ]
}

我如何使用 C# 生成这样的 JSON，我找到了如何制作 JSON 数组，但这就是我所拥有的。我不知道如何制作children":属性或者我不知道如何创建由其他 JSON 对象或其他 JSON 数组组成的 JSON 对象。您能给我一点帮助，以便我可以生成这样的 JSON 对象吗？谢谢。

使用匿名类型，您可以定义对象层次结构，几乎与使用纯 JSON 一样简单。然后只需使用序列化它Json.Net http://www.newtonsoft.com/json/help/html/SerializeObject.htm:

var obj = new {
    name = "flare",
    children = new[] {
        new { name = "analytics" },
        new { name = "animate" },
    }
};
var json = JsonConvert.SerializeObject(obj, Formatting.Indented);

对于更复杂的层次结构，您可能需要涉及动态类型。这是你的原始对象：

var obj = new {
    name = "flare",
    children = new[] {
        new {
            name = "analytics",
            children = new dynamic [] {
                new {
                    name = "cluster",
                    children = new dynamic [] {
                        new { name = "AgglomerativeCluster", size = 3938},
                        new { name = "MergeEdge", size = 743},
                    }
                },
                new {
                    name = "graph",
                    children = new dynamic [] {
                        new { name = "BetweennessCentrality", size = 3534},
                        new { name = "SpanningTree", size = 3416},
                    }
                },
                new {
                    name = "optimization",
                    children = new dynamic [] {
                        new { name = "AspectRatioBanker", size = 7074},
                    }
                },
            }
        },
        new {
            name = "animate",
            children = new dynamic [] {
                new { name = "Easing", size = 17010},
                new { name = "FunctionSequence", size = 5842},
                new {
                    name = "interpolate",
                    children = new [] {
                    new { name = "ArrayInterpolator",  size = 1983},
                    new { name = "RectangleInterpolator", size = 2042}
                    }
                },
                new { name = "ISchedulable", size = 1041},
                new { name = "Tween", size = 6006},
            }
        },
    }
};
var json = JsonConvert.SerializeObject(obj, Formatting.Indented);
