System.Text.Json Namespace
Provides high-performance, low-allocating, and standards-compliant capabilities to process JavaScript Object Notation (JSON), which includes serializing objects to JSON text and deserializing JSON text to objects, with UTF-8 support built-in. It also provides types to read and write JSON text encoded as UTF-8, and to create an in-memory document object model (DOM) for random access of the JSON elements within a structured view of the data.
Classes
| JsonDocument |
Provides a mechanism for examining the structural content of a JSON value without automatically instantiating data values. |
| JsonException |
Defines a custom exception object that is thrown when invalid JSON text is encountered, when the defined maximum depth is passed, or the JSON text is not compatible with the type of a property on an object. |
| JsonNamingPolicy |
Determines the naming policy used to convert a string-based name to another format, such as a camel-casing format. |
| JsonSerializer |
Provides functionality to serialize objects or value types to JSON and to deserialize JSON into objects or value types. |
| JsonSerializerOptions |
Provides options to be used with JsonSerializer. |
| Utf8JsonWriter |
Provides a high-performance API for forward-only, non-cached writing of UTF-8 encoded JSON text. |
Structs
| JsonDocumentOptions |
Provides the ability for the user to define custom behavior when parsing JSON to create a JsonDocument. |
| JsonElement |
Represents a specific JSON value within a JsonDocument. |
| JsonElement.ArrayEnumerator |
Represents an enumerator for the contents of a JSON array. |
| JsonElement.ObjectEnumerator |
Represents an enumerator for the properties of a JSON object. |
| JsonEncodedText |
Provides methods to transform UTF-8 or UTF-16 encoded text into a form that is suitable for JSON. |
| JsonProperty |
Represents a single property for a JSON object. |
| JsonReaderOptions |
Provides the ability for the user to define custom behavior when reading JSON. |
| JsonReaderState |
Defines an opaque type that holds and saves all the relevant state information, which must be provided to the Utf8JsonReader to continue reading after processing incomplete data. |
| JsonWriterOptions |
Allows the user to define custom behavior when writing JSON using the Utf8JsonWriter. |
| Utf8JsonReader |
Provides a high-performance API for forward-only, read-only access to UTF-8 encoded JSON text. |
Enums
| JsonCommentHandling |
Defines how the Utf8JsonReader struct handles comments. |
| JsonSerializerDefaults |
Specifies scenario-based default serialization options that can be used to construct a JsonSerializerOptions instance. |
| JsonTokenType |
Defines the various JSON tokens that make up a JSON text. |
| JsonValueKind |
Specifies the data type of a JSON value. |
