通过索引访问json对象数据

Question

我有以下数组结构的 json 对象。我正在尝试从对象数组中检索某些元素{"data": [{"_id": "5b62dc6ebef986403db8aafd","name": "smitha vijaya","designation": "account management","projects": {"project1": "description1","project2": "description2"},"age": "27"},{"_id": "5b62dd17bef986403db8ab90","name": "JIKKU VARGHESE","designation": "SUPERVISING OPERATIONS MANAGER","projects": {"project1": "description1","project2": "description2"},"age": "27"},{"_id": "5b62dd76bef986403db8abe3","name": "SUJEETH  NAIR","designation": "MENA AMS","projects": {"project1": "description1","project2": "description2"},"age": "30"},{"_id": "5b62ddb1bef986403db8ac13","name": "GIRISH   KN","designation": "MENA  AMS","projects": {"project1": "description1","project2": "description2"},"age": "27"}]}我正在使用以下 c# 代码来提取 ist 名称（smitha）JsonData jsonvale = JsonMapper.ToObject( jsonString);         Name = jsonvale["data"][0]["name"].ToString();print (name);我如何访问其他元素，如名称 jikku 等？

Answer 1

您可以使用 for 循环进行迭代：

for(int i = 0; i < jsonvale.length; i++) {

    JsonData jsonvale = JsonMapper.ToObject(jsonString);

    Name = jsonvale["data"][i]["name"].ToString();

    print(name);

}

Answer 2

只需在 List() 中反序列化这个 json，然后你就可以访问这个列表中的所有数据而无需循环，当你不再需要这个列表时，你可以销毁它。请参阅此示例https://github.com/IonCojucovschi/JsonDeserializeGenericForm

Answer 3

你可以像下面这样遍历你的 json 数组：

JsonData jsonvale = JsonMapper.ToObject( jsonString);

for (var i=0; i<jsonvale.length; i++){

    print(jsonvale["data"][i]["name"].ToString());

}
