.NET核心Web API中的自定义Json格式化程序

public class CustomJsonConverter : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        // 判断是否可以转换为指定类型的对象
        return objectType == typeof(MyObject);
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        // 从Json中读取对象
        JObject jsonObject = JObject.Load(reader);
        MyObject myObject = new MyObject();
        myObject.Property1 = (string)jsonObject["property1"];
        myObject.Property2 = (int)jsonObject["property2"];
        return myObject;
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        // 将对象写入Json
        MyObject myObject = (MyObject)value;
        JObject jsonObject = new JObject();
        jsonObject["property1"] = myObject.Property1;
        jsonObject["property2"] = myObject.Property2;
        jsonObject.WriteTo(writer);
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllers().AddJsonOptions(options =>
    {
        options.JsonSerializerOptions.Converters.Add(new CustomJsonConverter());
    });
}
