您似乎想要Dictionary<string, string>在JSON中将a表示为对象数组，其中每个嵌套对象都有一个来自字典的键和值。您可以使用以下转换器进行操作：
public class DictionaryToDictionaryListConverter<TKey, TValue> : JsonConverter
{
class DictionaryDTO : Dictionary<TKey, TValue>
{
public DictionaryDTO(KeyValuePair<TKey, TValue> pair) : base(1) { Add(pair.Key, pair.Value); }
}
public override bool CanConvert(Type objectType)
{
return typeof(IDictionary<TKey, TValue>).IsAssignableFrom(objectType) && objectType != typeof(DictionaryDTO);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
if (reader.TokenType == JsonToken.Null)
return null;
var token = JToken.Load(reader);
var dict = (IDictionary<TKey, TValue>)(existingValue as IDictionary<TKey, TValue> ?? serializer.ContractResolver.ResolveContract(objectType).DefaultCreator());
if (token.Type == JTokenType.Array)
{
foreach (var item in token)
using (var subReader = item.CreateReader())
serializer.Populate(subReader, dict);
}
else if (token.Type == JTokenType.Object)
{
using (var subReader = token.CreateReader())
serializer.Populate(subReader, dict);
}
return dict;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
var dict = (IDictionary<TKey, TValue>)value;
// Prevent infinite recursion of converters by using DictionaryDTO
serializer.Serialize(writer, dict.Select(p => new DictionaryDTO(p)));
}
}
然后在容器类中使用它，如下所示：
public class RootObject
{
[JsonProperty("value")]
[JsonConverter(typeof(DictionaryToDictionaryListConverter<string, string>))]
public Dictionary<string, string> Value { get; set; }
}
请注意，如果键不是唯一的，转换器将在读取过程中引发异常。
对于AddressValue您可以使用下面的转换器：
public class AddressValueConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return objectType == typeof(AddressValue);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
if (reader.TokenType == JsonToken.Null)
return null;
var addressValue = (existingValue as AddressValue ?? new AddressValue());
var token = JObject.Load(reader);
var property = token.Properties().SingleOrDefault();
if (property != null)
{
addressValue.Label = property.Name;
addressValue.Value = (string)property.Value;
}
return addressValue;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
var addressValue = (AddressValue)value;
serializer.Serialize(writer, new Dictionary<string, string> { { addressValue.Label, addressValue.Value } });
}
}
然后按以下方式使用它：
[JsonConverter(typeof(AddressValueConverter))]
public class AddressValue
{
public string Label { get; set; }
public string Value { get; set; }
}
public class RootObject
{
[JsonProperty("value")]
public List<AddressValue> Value { get; set; }
}
演示在这里摆弄了这两种选择。
