从 JSON 对象构建属性列表 c#

我想构建包含 json 对象的属性路径的属性列表。

我不知道 json 的结构或可能存在的键。我追求所有级别的键（而不是那些键的值）。

 {
  "Primitive_1": "T1",
  "Object_L1": {
    "Object_L2": {
      "Object_L3": {
        "Object_L4": {
          "Object_L5": {
            "Object_L6": {
              "Array_L7": [
                {
                  "asdasdas": "SampleText1",
                  "WIDTH": "Width2"
                },
                {
                  "gh45gdfg": "SampleText2",
                  "WIDTH": "Width"
                }
              ],
              "12836hasvdkl": "SampleText3",
              "WIDTH": "Width"
            }
          }
        },
        "712bedfabsmdo98": "SampleText4",
        "WIDTH": "Width"
      }
    },
    "ALIAS_ID": 1
  },
  "Primitive_2": "T2",
  "Primitive_3": "T3",
  "Primitive_4": "T4"
}

期望的输出：

.Primitive_1 .Object_L1.Object_L2.Object_L3.Object_L4.Object_L5.Object_L6.Array_L7.0.asdasdas
.Object_L1.Object_L2.Object_L3.Object_L4.Object_L5.Object_L6.Array_L7.0.WIDTH
.Object_L1.Object_L2.Object_L3.Object_L4.Object_L5.Object_L6.Array_L7.1.gh45gdfg
.Object_L1.Object_L2.Object_L3.Object_L4.Object_L5.Object_L6.Array_L7.1.WIDTH
.Object_L1.Object_L2.Object_L3.Object_L4.Object_L5.Object_L6.12836hasvdkl
.Object_L1.Object_L2.Object_L3.Object_L4.Object_L5.Object_L6.WIDTH
.Object_L1.Object_L2.Object_L3.712bedfabsmdo98
.Object_L1.Object_L2.Object_L3.WIDTH
.Object_L1.ALIAS_ID
.Primitive_2
.Primitive_3
.Primitive_4

环顾四周后，我已经到了对象的根节点。见小提琴（https://dotnetfiddle.net/wIl1Qw）

这在 JS 中似乎相对简单（http://jsfiddle.net/alteraki/bt3zc1wt/）我已经查看了几个响应，我无法在 c# 中找到解决此问题的响应而不知道使用的密钥（我不知道）

任何帮助将非常感激。

树遍历算法本质上几乎总是递归的。

因此，以下函数可以执行您想要的操作：

private static IEnumerable<string> GetMembers(JToken jToken)
{
    var members = new List<string>();

    if (jToken is JObject)
    {
        var jObject = (JObject)jToken;

        foreach (var prop in jObject.Properties())
        {
            if (prop.Value is JValue)
            {
                members.Add(prop.Name);
            }
            else
            {
                members.AddRange(GetMembers(prop.Value).Select(member => prop.Name + "." + member));
            }
        }
    }
    else if (jToken is JArray)
    {
        var jArray = (JArray)jToken;

        for (var i = 0; i < jArray.Count; i++)
        {
            var token = jArray[i];

            members.AddRange(GetMembers(token).Select(member => i + "." + member));
        }
    }

    return members;
}

此处提供了运行代码的示例。
