问题描述

我有以下JSON；

{
"b2c": {
    "languages": {
        "de": {
            "models": {
                "t300": {
                    "name": "Aveo",
                    "bodyTypes": {
                        "t300-4d-my13": {
                            "trimLevels": {
                                "lt": {
                                    "name": "LT",
                                    "variants": {
                                        "1.2_16V_86_Gas_MT": {
                                            "name": "1.2 MT",
                                            "price": {
                                                "EUR": {
                                                    "value": 13990,
                                                    "formatted": "13.990,00 €"
                                                }
                                            },
                                            "infoFeatures": {
                                                "fuel_consumption_extra_urban#consumption": {
                                                    "name": "Kraftstoffverbrauch außerorts ",
                                                    "value": "4.6",
                                                    "formatted": "4,6"
                                                },
                                                "top_speed#kilometer_per_hour": {
                                                    "name": "Höchstgeschwindigkeit",
                                                    "value": "171",
                                                    "formatted": "171"
                                                }
                                            },
                                            "images": null,
                                            "documents": null
                                        }
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }
    }
}
}

b2c，de，t300，t300-4d-my13等是动态的，但语言，模型，bodyType，trimLevels，变体，inforFeatures，图像和文档将保持不变。
我需要提取所有内容以访问值，例如语言。[ de]，模型。[ t300]。name，timeLevels。​​[ It]，变量和infoFeatures，作为这些键[]是动态的，所以我不确定要参考什么。

The values of b2c, de, t300, t300-4d-my13, It etc.. are dynamic but languages, models, bodyTypes, trimLevels, variants, inforFeatures, images and documents would remain same. I need to extract all to access values like languages.["de"], models.["t300"].name, timeLevels.["It"], Variants and infoFeatures, as these keys [""] are dynamics so I am not sure what to refer.

我已经尝试过，

    var jsonSerializer = new JsonSerializer();
    dynamic dynamicObject = jsonSerializer.Deserialize(new JsonTextReader(new StringReader(jsonString)));
    //var level1 = dynamicObject.b2c

我也已经看过了b 将JSON反序列化为C＃动态对象吗？

并尝试了

var dynamicObject = Json.Decode(jsonString);

但收到以下错误；

尝试通过方法'System.Web.Helpers.Json.Decode（System.String）'访问字段'System.Web.Helpers.Json._serializer'。

Attempt by method 'System.Web.Helpers.Json.Decode(System.String)' to access field 'System.Web.Helpers.Json._serializer' failed.

推荐答案

对于我们来说，它有助于从顶部答案中取消选中项目属性>调试选项卡中的启用Visual Studio托管过程。到通过方法'System尝试.Web.Helpers.Json..cctor（）访问方法 System.Web.Helpers.Json.CreateSerializer（）失败

For us it helped to uncheck "Enable the Visual Studio hosting process" in the Project properties > Debug tab, from the top answer to Attempt by method 'System.Web.Helpers.Json..cctor()' to access method 'System.Web.Helpers.Json.CreateSerializer()' failed
