DefaultValueHandling单独免除布尔值

Question

在使用json.net序列化时，我使用了DefaultValueHandling。在序列化设置中忽略，如果bool设置为false，则会导致删除键。我想只对bool类型免税，并申请其他类型和类。请帮助

序列化设置中的DefaultValueHandling.Ignore可以通过用[JsonProperty(DefaultValueHandling = DefaultValueHandling.Include)]属性装饰任何属性来覆盖。下面是类:

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
    [JsonProperty(DefaultValueHandling = DefaultValueHandling.Include)]
    public bool IsEmployed { get; set; }
}

假设我们有以下样品:

var person = new Person
            {
                FirstName = "John",
                IsEmployed = false
            };
var json = JsonConvert.SerializeObject(person, new JsonSerializerSettings { DefaultValueHandling = DefaultValueHandling.Ignore });

将导致如下json:

{
    "FirstName": "John",
    "IsEmployed": false
}
