Newtonsoft - 反序列化“1”作为条件布尔属性

Question

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",

和以下 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; }
}

和反序列化代码：

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

但是我对IsActive属性有问题，因为 json 对象有 1 或 0 个值，但我想有布尔值。如何编写 JsonSerializer 来做到这一点？

Pete 非常好的代码，介绍如何让 newtonsoft 将 yes 和 no 反序列化为布尔值

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;
}

}

用法：

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