将字典扩展为JSON字段

本文关键字:JSON 字段 扩展 字典 | 更新日期: 2023-09-27 18:06:11

我们有这样的DTO类:

public class DTO
    {
        public int Number { get; set; }
        public string Title { get; set; }
        public Dictionary<string, string> CustomFields { get; set; }
    }

我想通过ServiceStack序列化/反序列化DTO到JSON,其中CustomFields扩展为DTO字段。例如

new DTO 
{
    Number = 42
    Title = "SuperPuper"
    CustomFields = new Dictionary<string, string> {{"Description", "HelloWorld"}, {"Color", "Red"}}
}

序列化到

{
    "Number":42,
    "Title":"SuperPuper",
    "Description":"HelloWorld",
    "Color":"Red"
}

我怎样才能做到这一点?

  • 在序列化过程中,所有字典字段必须表示为JSON对象字段。
  • 所有传入JSON对象的非DTO字段必须在反序列化过程中放入Dictionary。

将字典扩展为JSON字段

如果您使用Newtonsoft库,您可以这样做:

   DTO Test = new DTO
   {
       Number = 42,
       Title = "SuperPuper",
       CustomFields = new Dictionary<string, string> { { "Description", "HelloWorld" }, { "Color", "Red" } }
   };
    String Json = Newtonsoft.Json.JsonConvert.SerializeObject(Test);
    Json = Json.Replace("'"CustomFields'":{", "");
    Json = Json.Replace("}}", "}");

结果json字符串看起来像这样:

{"Number":42,"Title":"SuperPuper","Description":"HelloWorld","Color":"Red"}

我不会做你所有的工作…这应该可以让你开始:
// to reconstruct the object
Newtonsoft.Json.Linq.JObject MyObject = Newtonsoft.Json.JsonConvert.DeserializeObject(Json) as Newtonsoft.Json.Linq.JObject;
// Create a new object here.
foreach( var Token in MyObject)
{         
    // sample  
    if (Token.Key == "Number")
    {
        // populate the fields of the new object with Token.Value
    }      
}
