问题描述
在使用 json.net 进行序列化时，我在序列化设置中使用了 DefaultValueHandling.Ignore，如果 bool 设置为 false，则会导致删除键.我希望仅对 bool 类型豁免，并申请其他类型和类.请帮忙
While serializing using json.net i used DefaultValueHandling.Ignore in serialization settings, which result in removal of key if the bool is set false. I want that to be exempted for type bool alone, and apply for other types and classes. Please help
提前致谢.
推荐答案
DefaultValueHandling.Ignore 在序列化设置中可以通过使用 [JsonProperty(DefaultValueHandling = DefaultValueHandling.Include) 装饰任何属性来覆盖] 属性.这是课程:
DefaultValueHandling.Ignore in serialization settings can be overridden by decorating any property with [JsonProperty(DefaultValueHandling = DefaultValueHandling.Include)] attribute. Here is the class:
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
[JsonProperty(DefaultValueHandling = DefaultValueHandling.Include)]
public bool IsEmployed { get; set; }
}
假设我们有以下示例:
var person = new Person
{
FirstName = "John",
IsEmployed = false
};
var json = JsonConvert.SerializeObject(person, new JsonSerializerSettings { DefaultValueHandling = DefaultValueHandling.Ignore });
将产生以下 json:
Will result in following json:
{
"FirstName": "John",
"IsEmployed": false
}
