JavaScriptSerializer-枚举的JSON序列化为字符串 [英] JavaScriptSerializer - JSON serialization of enum as string
问题描述
我有一个包含enum属性的类，并且在使用JavaScriptSerializer序列化对象时，我的json结果包含枚举的整数值，而不是其string"name".有没有一种方法可以在我的json中将枚举作为string获取而无需创建自定义JavaScriptConverter?也许有一个属性可以装饰enum定义或对象属性?
I have a class that contains an enum property, and upon serializing the object using JavaScriptSerializer, my json result contains the integer value of the enumeration rather than its string "name". Is there a way to get the enum as a string in my json without having to create a custom JavaScriptConverter? Perhaps there's an attribute that I could decorate the enum definition, or object property, with?
例如:
enum Gender { Male, Female }
class Person
{
int Age { get; set; }
Gender Gender { get; set; }
}
所需的json结果:
{ "Age": 35, "Gender": "Male" }
理想情况下，使用内置的.NET框架类寻找答案，如果可能的话，也欢迎使用替代方法(如Json.net).
Ideally looking for answer with built-in .NET framework classes, if not possible alternatives (like Json.net) are welcome.
推荐答案
没有没有可以使用的特殊属性. JavaScriptSerializer将enums序列化为其数值，而不是其字符串表示形式.您需要使用自定义序列化来序列化enum作为其名称而不是数字值.
No there is no special attribute you can use. JavaScriptSerializer serializes enums to their numeric values and not their string representation. You would need to use custom serialization to serialize the enum as its name instead of numeric value.
如果您可以使用JSON.Net代替JavaScriptSerializer，那么请参阅[JsonConverter(typeof(StringEnumConverter))])以及许多其他内置方法未处理的用例.网络序列化器. 这是一个比较串行器特性和功能的链接.
If you can use JSON.Net instead of JavaScriptSerializer than see answer on this question provided by OmerBakhari: JSON.net covers this use case (via the attribute [JsonConverter(typeof(StringEnumConverter))]) and many others not handled by the built in .net serializers. Here is a link comparing features and functionalities of the serializers.
