  }
}

使用Newtonsoft JSON库，我不知道如何做到这一点。使用在线转换器，它创建一个名为MultiOptions的类，然后将所有这些作为属性。

Answer 1

是的，有可能，你需要使用System.Reflection

public Root MyDeserializedClass = new Root();
public Dictionary<string, string> MyDictionary = new Dictionary<string, string>();
...
private void Button_Clicked_1(object sender, EventArgs e)
{
   ConvertToDictionaryPair();
}

private void ConvertToDictionaryPair()
{
   PropertyInfo[] properties = MyDeserializedClass.multiOptions.GetType().GetProperties();
   foreach (PropertyInfo property in properties)
   {
       string key = property.Name;
       string value = property.GetValue(MyDeserializedClass.multiOptions).ToString();
       if (!MyDictionary.ContainsKey(key))
           MyDictionary.Add(key, value);
   }
}

模型

public class Root
    {
        public string type { get; set; }
        public string name { get; set; }
        public string label { get; set; }
        public string description { get; set; }
        public MultiOptions multiOptions { get; set; }
    }

    public class MultiOptions
    {
        [JsonProperty("US/Pacific")]
        public string USPacific { get; set; }
        [JsonProperty("US/Mountain")]
        public string USMountain { get; set; }
        [JsonProperty("US/Central")]
        public string USCentral { get; set; }
        [JsonProperty("US/Eastern")]
        public string USEastern { get; set; }
        [JsonProperty("America/Halifax")]
        public string AmericaHalifax { get; set; }
        [JsonProperty("America/Anchorage")]
        public string AmericaAnchorage { get; set; }
        [JsonProperty("Pacific/Honolulu")]
        public string PacificHonolulu { get; set; }
        [JsonProperty("Pacific/Samoa")]
        public string PacificSamoa { get; set; }
        [JsonProperty("Etc/GMT-12")]
        public string EtcGMT12 { get; set; }
        [JsonProperty("Canada/Newfoundland")]
        public string CanadaNewfoundland { get; set; }
        [JsonProperty("America/Buenos_Aires")]
        public string AmericaBuenosAires { get; set; }
        [JsonProperty("Atlantic/South_Georgia")]
        public string AtlanticSouthGeorgia { get; set; }
        [JsonProperty("Atlantic/Azores")]
        public string AtlanticAzores { get; set; }
        [JsonProperty("Europe/London")]
        public string EuropeLondon { get; set; }
        [JsonProperty("Europe/Berlin")]
        public string EuropeBerlin { get; set; }
        [JsonProperty("Europe/Athens")]
        public string EuropeAthens { get; set; }
        [JsonProperty("Europe/Moscow")]
        public string EuropeMoscow { get; set; }
        public string Iran { get; set; }
        [JsonProperty("Asia/Dubai")]
        public string AsiaDubai { get; set; }
        [JsonProperty("Asia/Kabul")]
        public string AsiaKabul { get; set; }
        [JsonProperty("Asia/Yekaterinburg")]
        public string AsiaYekaterinburg { get; set; }
        [JsonProperty("Asia/Calcutta")]
        public string AsiaCalcutta { get; set; }
        [JsonProperty("Asia/Katmandu")]
        public string AsiaKatmandu { get; set; }
        [JsonProperty("Asia/Omsk")]
        public string AsiaOmsk { get; set; }
        [JsonProperty("India/Cocos")]
        public string IndiaCocos { get; set; }
        [JsonProperty("Asia/Krasnoyarsk")]
        public string AsiaKrasnoyarsk { get; set; }
        [JsonProperty("Asia/Hong_Kong")]
        public string AsiaHongKong { get; set; }
        [JsonProperty("Asia/Tokyo")]
        public string AsiaTokyo { get; set; }
        [JsonProperty("Australia/Adelaide")]
        public string AustraliaAdelaide { get; set; }
        [JsonProperty("Australia/Sydney")]
        public string AustraliaSydney { get; set; }
        [JsonProperty("Asia/Magadan")]
        public string AsiaMagadan { get; set; }
        [JsonProperty("Pacific/Auckland")]
        public string PacificAuckland { get; set; }
    }

首先单击Get数据并填充模型，然后单击set Data，然后遍历模型并将每个属性名称和值添加到字典中。

您可以给Newtonsoft一个要反序列化的DTO。

var parsedDto = JsonConvert.DeserializeObject<ParsedJsonResponseDto>(jsonResponse);

其中DTO对象看起来类似于。

public class ParsedJsonResponseDto
{
    [JsonProperty("type")]
    public string Type { get; set; }

    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("label")]
    public string Label { get; set; }

    [JsonProperty("description")]
    public string Description { get; set; }

    [JsonProperty("multiOptions")]
    public Dictionary<string, string> MultiOptions { get; set; }    
}

既然有了MultiOptions字典中的对象，就可以任意迭代。
