将JSON反序列化为Dictionary< string，string> [英] Deserialise JSON to Dictionary<string, string >

问题描述

当我从极其松散的PHP迁移到F#时，我肯定会有来自我的愚蠢问题.

I’m sure there will be a barrage of stupid questions from me as I migrate away from the extremely loose PHP to F#.

希望这应该很简单.我有一个json文件

This one should hopefully be straightforward. I have a json file

{
"some_ key" : "some_value"
}

它将以简单的键，值(字符串，字符串)格式列出几百个项目.

That will have a list of a few hundred items in a simple key,value (string,string) format.

在F#中，我想将该字符串解码为 dictionary< string，string>.似乎很明显，但是我所看到的所有建议似乎都太冗长了，所以假设我缺少一些简单的东西.

In F# I’d like to decode that string into a dictionary<string, string> . Seems obvious enough but all suggestions I’ve seen seem extremely verbose so assume I’m missing something simple.

我可以使用Thoth和FSharp.Data，尽管可以免费使用其他任何软件.

I have Thoth and FSharp.Data at my disposal, though open to anything else free.

推荐答案

纯净的.NET Core示例，如果您只是简单的事情:

A pure .NET Core example if you are only after something simple:

let json = """{
  "some_ key" : "some_value"
}"""

let data = 
    System.Text.Json.JsonDocument.Parse(json)
        .RootElement
        .EnumerateObject()
    |> Seq.map (fun o -> o.Name, o.Value.GetString())
    |> dict
