This sample demonstrates the following features: Serialize and deserialize JSON objects using theJsonObjectclass. Serialize and deserialize JSON arrays using theJsonArrayclass. Serialize and deserialize strings using theJsonValueclass. Serialize and deserialize numbers using theJsonValueclass. ...
Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: std::string for strings, int64_t, uint64_t or double for numbers, std::map for objects, std::vector for ...
Creates a field mapping function that transforms a string formatted as a JSON array of strings into a string array that can be used to populate a Collection(Edm.String) field in the index. C# 複製 public static Microsoft.Azure.Search.Models.FieldMappingFunction JsonArrayToStringCollecti...
