使用JSON JArray获得价值 [英] Get Value from JSON using JArray

问题描述

我有以下字符串（JSON格式）结果
我从服务器获得：

I have the following string (json format)
I have gotten from my server:

{[{"ruta": "1","division": "7"},{"ruta": "2","division": "7"},{"ruta": "3","division":"7"},{"ruta": "4","division": "7"},{"ruta": "5","division": "7"},{"ruta": "23","division": "7"}]}

我想每个值，并将其保存在为了将它们保存在数据库字符串变量。

I want to get each value and save them in string variables in order to save them in a data base.

有关，我尝试做如下：

JArray jarr = JArray.Parse(result);
foreach (JObject content in jarr.Children<JObject>())
{
    foreach (JProperty prop in content.Properties())
    {
         string tempValue = prop.Value.ToString; // This is not allowed 
         //here more code in order to save in a database
    }
}

但我不能找到这些值转换为字符串的方式。

But I can't find the way to convert the values to string.

推荐答案

使用的ToString（），而不是的ToString 。

的ToString（）是一个方法调用; 的ToString 是的ToString 方法的引用，只能被分配到一个兼容的委托。

ToString() is a method call; ToString is a reference to the ToString method, and can only be assigned to a compatible delegate.

您也可以转换为字符串，因为 JToken 类定义的转换

You can also cast to String, since the JToken class defines a conversion:

string tempValue = (string)prop.Value;

要考虑的另一个选择是使用JSON序列：创建表示JSON数据的类（用相同的结构），和反序列化的JSON此类。它使代码更具有可读性和可维护性。

Another option to consider is to use JSON serialization: create a class that represents the JSON data (with the same structure), and deserialize the JSON to this class. It makes the code much more readable and maintainable.
