将 Json 字符串嵌套到 vb.net 或 uipath

如何解决将 Json 字符串嵌套到 vb.net 或 uipath

我有 json 字符串，它具有嵌套级别和正常的组合，如下面的字符串所示。我想提取如下值。从“FrameVariables”

中提取所需的值

arrary1：二维数组（位置、性别、国籍的组合）

{

（利雅得，男性，沙特国民）（沙特国民的目标），

（利雅得，男性，外籍阿拉伯人）（外籍阿拉伯人的目标），

（利雅得，女性，沙特国民）（沙特国民的目标）

（利雅得，女性，外籍阿拉伯人）（外籍阿拉伯人的目标），

（吉达，男，沙特国民）（沙特国民的目标），

.

.

.

(Damam,Male,Saudi National)(Saudi National 的目标),

...

(Damam,female,Expat Arab)(Expat Arab的对象)

}

Array2：二维数组（年龄） { (18 - 25 岁),(目标 18 - 25 岁),(26 - 35 岁),(目标 26 - 35 岁),(36 - 50 年),(目标 36 - 50 年) }

注意事项：这个json是动态的，值和名称会根据数据变化。

示例 Json 字符串：

解决方法

使用 Deserialize Json。这可以反序列化 JSON 对象和 JSON 数组。对于对象内的内容，只需多次应用该活动。
