dotnet add package Newtonsoft.Json
So pour one out for the DLL that refused to die. And then maybe add a reference to it, because your appsettings.json file still needs parsing.
// Serialize to JSON string json = JsonConvert.SerializeObject(person); Console.WriteLine(json);
public class UnixDateTimeConverter : JsonConverter<DateTime> newtonsoft json dll
This is where Newtonsoft left every competitor in the dust. The JsonSerializerSettings object allows you to tweak everything :
| Feature | Newtonsoft.Json | System.Text.Json | |---------|----------------|------------------| | Default property name casing | Preserved | camelCase | | Non-public members | Can serialize with opt-in | Not supported | | Dictionary with non-string keys | Serializes as JSON object | Throws or requires converter | | Cyclic references | ReferenceLoopHandling.Ignore | Not supported | | DateTime handling | ISO by default | Strict ISO (no legacy formats) |
public class Person
Benchmarked to be up to 50% faster than older built-in serializers like DataContractJsonSerializer .
But that simple description is like calling a Swiss Army knife "a thing with a blade." The real power lies in the nuance.
string json = @" 'store': 'book': [ 'title': 'The Hobbit' ] "; JObject obj = JObject.Parse(json); string title = obj["store"]["book"][0]["title"].ToString(); obj["store"]["book"][0]["price"] = 12.99; // Modify in place dotnet add package Newtonsoft
Newtonsoft.Json.dll, also known as JSON.NET, is a widely-used .NET library for working with JSON data. Developed by James Newton-King, it provides a simple and efficient way to serialize and deserialize JSON data in .NET applications.
The file, part of the widely known Json.NET library created by James Newton-King, is the most successful and robust JSON framework ever built for the Microsoft .NET ecosystem. Serving as the bedrock for millions of applications, this Dynamic Link Library (DLL) provides deep, high-performance mechanisms to convert strongly typed .NET objects into text-based JSON strings (serialization) and turn raw JSON payloads back into native data formats (deserialization).
