尝试使用jSonstringEnumConverter将枚举转换为自定义字符串名称

发布于 2025-02-07 18:29:23 字数 784 浏览 0 评论 0原文

我试图代表以下的一些用例场景。我有JSON格式化的数据。它包括一个枚举课程。他们以int类型发送了这个枚举类。我想用有意义的字符串显示此枚举值。但是我做不到。

如何显示此本登录自定义值？

编辑：我想显示“不热”值。不是Hot_Not枚举。

static void Main(string[] args) {
    var jsonString = "{\"Summary\":\"40\"}";
    var options = new JsonSerializerOptions {
        Converters = {
            new JsonStringEnumConverter()
        }
    };
    WeatherForecastWithEnum ? weatherForecast = JsonSerializer.Deserialize < WeatherForecastWithEnum > (jsonString, options) !;
    Console.WriteLine(weatherForecast.Summary);
}

public class WeatherForecastWithEnum {
    public Summary ? Summary {
        get;
        set;
    }
}

public enum Summary {
    Cold = 30,
    Cool = 10,
    Warm = 20,
    [EnumMember(Value = "Not Hot")]
    Hot_Not = 40
}

I was trying represent some use-case scenario like below. I have json formatted data. And it include an enum class. They send this enum class with int type. I want to show this enum value with a meaningful string. But I couldn't make it.

How can I show this EnumMember custom value?

Edit: I want to show "Not Hot" value. Not Hot_Not enum.

static void Main(string[] args) {
    var jsonString = "{\"Summary\":\"40\"}";
    var options = new JsonSerializerOptions {
        Converters = {
            new JsonStringEnumConverter()
        }
    };
    WeatherForecastWithEnum ? weatherForecast = JsonSerializer.Deserialize < WeatherForecastWithEnum > (jsonString, options) !;
    Console.WriteLine(weatherForecast.Summary);
}

public class WeatherForecastWithEnum {
    public Summary ? Summary {
        get;
        set;
    }
}

public enum Summary {
    Cold = 30,
    Cool = 10,
    Warm = 20,
    [EnumMember(Value = "Not Hot")]
    Hot_Not = 40
}

默认情况下，system.text.json不支持它。您可以看到相同的请求。

https://github.com/dotnet/runtime/runtime/issues/issues/31081 一个称为“ macross.json.extensions”的扩展库，您可以在其中使用jSonstringEnummemberConverter属性，然后执行您需要的事情。

JsonConverter(typeof(JsonStringEnumMemberConverter))]
public enum DefinitionType
{
   [EnumMember(Value = "UNKNOWN_DEFINITION_000")]
   DefinitionUnknown
}

     [TestMethod]
    public void ExampleTest()
    {
        string Json =  JonSerializer.Serialize(DefinitionType.DefinitionUnknown);

        Assert.AreEqual("\"UNKNOWN_DEFINITION_000\"", Json);

        DefinitionType ParsedDefinitionType =    JsonSerializer.Deserialize<DefinitionType>(Json);

         Assert.AreEqual(DefinitionType.DefinitionUnknown, ParsedDefinitionType);
   }

您可以在 - https：// https：// github.com/macross-software/core/tree/develop/classlibraries/macross.json.extensions#enumerations

By default, it is not supported with System.Text.Json . You can see the request for the same.

https://github.com/dotnet/runtime/issues/31081

But there is an extension library called 'Macross.Json.Extensions' where you can use JsonStringEnumMemberConverter attribute and then do what you need.

JsonConverter(typeof(JsonStringEnumMemberConverter))]
public enum DefinitionType
{
   [EnumMember(Value = "UNKNOWN_DEFINITION_000")]
   DefinitionUnknown
}

     [TestMethod]
    public void ExampleTest()
    {
        string Json =  JonSerializer.Serialize(DefinitionType.DefinitionUnknown);

        Assert.AreEqual("\"UNKNOWN_DEFINITION_000\"", Json);

        DefinitionType ParsedDefinitionType =    JsonSerializer.Deserialize<DefinitionType>(Json);

         Assert.AreEqual(DefinitionType.DefinitionUnknown, ParsedDefinitionType);
   }
