JsonDataSource Leave feedback

Provides access to data of a JSON file or stream to be used while assembling a document.

public class JsonDataSource

To access data of the corresponding file or stream while assembling a document, pass an instance of this class as a data source to one of DocumentAssembler.AssembleDocument overloads.

In template documents, if a top-level JSON element is an array, a JsonDataSource instance should be treated in the same way as if it was a DataTable instance. If a top-level JSON element is an object, a JsonDataSource instance should be treated in the same way as if it was a DataRow instance. For more information, see template syntax reference (https://docs.groupdocs.com/display/assemblynet/Template+Syntax+-+Part+1+of+2#TemplateSyntax-Part1of2-UsingDataSources).

In template documents, you can work with typed values of JSON elements. For convenience, the engine replaces the set of JSON simple types with the following one:

• long?
• double?
• bool?
• DateTime?
• string

The engine automatically recognizes values of the extra types upon their JSON representations.

To override default behavior of JSON data loading, initialize and pass a JsonDataLoadOptions instance to a constructor of this class.
