c# - JavaScriptSerializer-枚举的JSON序列化为字符串(JavaScriptSerializer - JSON serialization of enum as string)

Question

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".

(我有一个包含enum属性的类，并在使用JavaScriptSerializer序列化对象后，我的json结果包含枚举的整数值，而不是其string “ name”。)

Is there a way to get the enum as a string in my json without having to create a custom JavaScriptConverter ?

(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 ？)

Perhaps there's an attribute that I could decorate the enum definition, or object property, with?

(也许有一个属性可以修饰enum定义或对象属性？)

As an example:

(举个例子：)

enum Gender { Male, Female }

class Person
{
    int Age { get; set; }
    Gender Gender { get; set; }
}

Desired json result:

(所需的json结果：)

{ "Age": 35, "Gender": "Male" }

Ideally looking for answer with built-in .NET framework classes, if not possible alternatives (like Json.net) are welcome.

(理想情况下，使用内置的.NET框架类寻找答案，如果可能的话，欢迎使用替代方法（如Json.net）。)

Answer 1

I have found that Json.NET provides the exact functionality I'm looking for with a StringEnumConverter attribute:

(我发现Json.NET通过StringEnumConverter属性提供了我正在寻找的确切功能：)

using Newtonsoft.Json;
using Newtonsoft.Json.Converters;

[JsonConverter(typeof(StringEnumConverter))]
public Gender Gender { get; set; }

More details at available on StringEnumConverter documentation .

(有关更多详细信息，请StringEnumConverter文档 。)

There are other places to configure this converter more globally:

(还有其他地方可以更全局地配置此转换器：)

• enum itself if you want enum always be serialized/deserialized as string:

  (枚举本身，如果您想让枚举始终被序列化/反序列化为字符串：)

   [JsonConverter(typeof(StringEnumConverter))] enum Gender { Male, Female } 

• In case anyone wants to avoid attribute decoration, you can add the converter to your JsonSerializer (suggested by Bj?rn Egil ):

  (如果有人想避免装修的属性，你可以转换器添加到您的JsonSerializer（所建议比约恩埃吉尔 ）：)

   serializer.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter()); 

  and it will work for every enum it sees during that serialization (suggested by Travis ).

  (并且它将对在序列化期间看到的每个枚举都有效（由Travis建议）。)

• or JsonConverter (suggested by banana ):

  (或JsonConverter（由香蕉建议）：)

   JsonConvert.SerializeObject(MyObject, new Newtonsoft.Json.Converters.StringEnumConverter()); 

Additionally you can control casing and whether numbers are still accepted by using StringEnumConverter(NamingStrategy, Boolean) constructor.

(另外，您可以使用StringEnumConverter（NamingStrategy，Boolean）构造函数来控制大小写以及是否仍接受数字。)
