这个问题已经有了答案:

Convert an int to bool with Json.Net [duplicate] 1答

我有以下JSON对象:

  {
    "entity": "Customer",
    "id": "XXX",
    "isActive": "1",
    "createdTime": "2018-01-30T18:56:51+02:00",
    "updatedTime": "2019-01-05T02:15:17+02:00",

以及以下DTO类:

public class Customer
{
    public string Id { get; set; }
    public bool IsActive { get; set; }
    public DateTime CreatedTime { get; set; }
    public DateTime UpdatedTime { get; set; }
}

反序列化代码:

        var jsonResponse = JObject.Parse(customerString);
        JToken array = jsonResponse["response_data"];
        List<Customer> result = (List<Customer>)array.ToObject(typeof(List<Customer>));

但是我有个问题 IsActive 属性,因为JSON对象有1或0个值,但我希望有布尔值。如何编写JSonserializer来完成它?

皮特的密码很好 how to get newtonsoft to deserialize yes and no to boolean

public class JsonBooleanConverter : JsonConverter
{
    public override bool CanWrite { get { return false; } }

public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
    throw new NotImplementedException();
}

public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
    var value = reader.Value.ToString().ToLower().Trim();
    switch (value)
    {
        case "true":
        case "yes":
        case "y":
        case "1":
            return true;
    }
    return false;
}

public override bool CanConvert(Type objectType)
{
    if (objectType == typeof(Boolean))
    {
        return true;
    }
    return false;
}

}

用途:

var myObj = JsonConvert.DeserializeObject<T>(json, new JsonBooleanConverter())
