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。
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"}
[编辑]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
}
}
