Text.Json.Nodes 程序集: System.Text.Json.dll Source: JsonArray.cs 返回一个可枚举值,用于包装对 的 GetValue<T>()调用。 C# 复制 public System.Collections.Generic.IEnumerable<T> GetValues<T>(); 类型参数 T 要从JsonValue获取的值的类型。 返回 IEnumerable<T> 对数组值的可枚举迭代。
首先,创建表并加载数据: CREATETABLEuser_logs(log_string STRING);-- 将JSON数据插入到表中INSERTINTOuser_logsVALUES('{"user_id": "12345", "activities": [{"type": "click", "timestamp": "2023-10-01T00:00:00Z"}, {"type": "purchase", "timestamp": "2023-10-01T01:00:00Z"}, {"ty...

上面是搜索网上的结论的截图,基本都会认为json_tuple比get_json_object高效,理由是:取多个key值时,json_tuple只解析一次,而get_json_object需要解析多次。 我们来看实际情况: 1、get_json_object缓存jsonObject (并非无脑解析多次) 一般情况下,由json字符串序列化成jsonObject这个过程是最耗费时间的。从代码中可以看...

JSON is a data-interchange format with syntax rules that are stricter than those of JavaScript's object literal notation. For example, all strings represented in JSON, whether they are properties or values, must be enclosed in double-quotes. For details on the JSON format, seehttps://json....
