问题描述

寻找一个函数，该函数将 Json 的 string 作为输入，并使用换行符和缩进对其进行格式化.验证将是一个奖励，但不是必需的，我不需要将其解析为对象或任何东西.

Looking for a function that will take a string of Json as input and format it with line breaks and indentations. Validation would be a bonus, but isn't necessary, and I don't need to parse it into an object or anything.

有人知道这样的图书馆吗?

Anyone know of such a library?

示例输入:

{"status":"OK", "results":[ {"types":[ "locality", "political"], "formatted_address":"New York, NY, USA", "address_components":[ {"long_name":"New York", "short_name":"New York", "types":[ "locality", "political"]}, {"long_name":"New York", "short_name":"New York", "types":[ "administrative_area_level_2", "political"]}, {"long_name":"New York", "short_name":"NY", "types":[ "administrative_area_level_1", "political"]}, {"long_name":"United States", "short_name":"US", "types":[ "country", "political"]}], "geometry":{"location":{"lat":40.7143528, "lng":-74.0059731}, "location_type":"APPROXIMATE", "viewport":{"southwest":{"lat":40.5788964, "lng":-74.2620919}, "northeast":{"lat":40.8495342, "lng":-73.7498543}}, "bounds":{"southwest":{"lat":40.4773990, "lng":-74.2590900}, "northeast":{"lat":40.9175770, "lng":-73.7002720}}}}]} 

推荐答案

这对我在 .Net Core 3.1 中使用 System.Text.Json 有效

This worked for me using System.Text.Json in .Net Core 3.1

 public string PrettyJson(string unPrettyJson)
 {
     var options = new JsonSerializerOptions(){
         WriteIndented = true
     };

     var jsonElement = JsonSerializer.Deserialize<JsonElement>(unPrettyJson);

     return JsonSerializer.Serialize(jsonElement, options);
 }
