使用 Json.NET 将 F# 可变变量序列化为 JSON 会生成重复项 [英] Serialization of F# mutable variable to JSON using Json.NET generates duplicated items

问题描述

这是我的代码:

 open Newtonsoft.Json
 open Newtonsoft.Json.Converters

 type T = {
     mutable name : string;
     mutable height : int;
     }

 let a = { name = "abc"; height = 180;}
 a.height  <- 200
 let b = JsonConvert.SerializeObject(a, Formatting.Indented)
 printfn "%s"  b

代码的输出为:

{
  "name@": "abc",
  "height@": 200,
  "name": "abc",
  "height": 200
}

如何避免属性中带有@"的输出?

How can I avoid the outputs with '@' in the properity?

推荐答案

试试这个:

[<CLIMutable>]
[<JsonObject(MemberSerialization=MemberSerialization.OptOut)>]
type T = {
    name : string;
    height : int;
    }

MemberSerialization.OptOut 仅导致公共成员被序列化(跳过作为记录实现细节的私有字段).CLIMutable 属性是 专门用于序列化，并且不必为每个成员添加 mutable 前缀.

MemberSerialization.OptOut causes only public members to be serialized (skipping private fields which are an implementation detail of records). The CLIMutable attribute is intended specifically for serialization and saves from having to prefix each member with mutable.
