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

代码的输出是:

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

如何以正确的"@"来避免输出？
