All about the new System.Text.Json namespace.

• Json

  Use JsonSerializer.SerializeAsync to serializer your object to JSON directly to stream.

• Json - Options

  Use JsonSerializerOptions to control certain aspect of your object serialization.

• Json - Serializing Anonymous Type

  Create adhoc JSON document using anonymous type and serialize it to stream directly using JsonSerializer.SerializeAsync.

• Json - Control serialization using attributes

  Use [JsonPropertyName] and [JsonIgnore] to control JSON serialization output.

• Json - Serialize a Dictionary of object

  A Dictionary<string, object> can be used to generate pretty much any shape of JSON document that you want.

• Json - Write a JSON document to the stream directly

  Use Utf8JsonWriter to write a JSON document directly to a stream.

• Json - Implement a custom naming policy

  Create a custom naming policy that generate JSON property names in snake_case.

• Json - Benchmark

  Benchmark on two different approaches of generating snake_case property names.

• Json - Custom Converter

  Implement a custom type converter. In this example we convert TimeSpan.

• Json - Control JsonIgnore behaviour

  Demonstrate the three different ways you can control the behaviour of [JsonIgnore] per property.

• Json - Custom Converter 2

  Implement a custom type coverter for DateTime type for JsonSerializer in the format of JSON date ticks.

Design document for the Writable JSON API

• Primitives

  This sample shows how to parse and access number, string and an array values from JSON string.

• Object

  This sample shows how to parse and access objects from JSON string. We will be using JsonObject as well.

• Finding a node using LINQ

  This sample shows how to find a node based on of its value using LINQ.

• Finding a node using LINQ 2

  This sample shows how to find a node based on two of its values (a string and an array) using LINQ.

• Finding a node using LINQ 3

  This sample shows how to find a node based of an absence of a property using LINQ.

• Finding a node using LINQ 4

  In this example we are trying to find a node in an array that has a specific value on its array property.

• Construct a JSON document

  This sample shows how to construct a JSON document using JsonObject.

• Construct a JSON document

  This sample shows how to construct a JSON document using JsonArray.

• Update a JSON document

  This sample shows how to update properties of a JSON document.

• Delete elements in a JSON document

  This example shows how to update remove an object property and an element in an array.

• Add items into a JSON array

  This example shows how to add items at the first position of an array and at the last position.

• JSON - 23

  Show how to customize serialization using DefaultJsonTypeInfoResolver.

• JSON - 24

  Customize serialization by writing number as string in JSON for Age values.

• JSON - 25

  In this case we add one extra timestamp property to the serialization process.

• JSON - 26

  This sample shows how to detect the type of a JSON property.
