反序列化到JSON字符串数组 [英] Deserializing JSON into string array

问题描述

我刚开始用C＃涉足，而我一直在敲打我的头以上的JSON反序列化，现在一会儿。我使用Newtonsoft.Json库。我期待字典的数组，这样

I just started dabbling with C#, and I've been banging my head over JSON deserialization for a while now. I'm using Newtonsoft.Json library. I'm expecting just a json response of an array of dictionaries as such

[{"id":"669","content":" testing","comments":"","ups":"0","downs":"0"}, {"id":"482","content":" test2","comments":"","ups":"0","downs":"0"}]

现在我有：（注：下载只是一个字符串持有JSON字符串）

Right now I have: (note: download is just a string holding the json string)

string[] arr = JsonConvert.DeserializeObject<string[]>(download);

我已经尝试了许多不同的这样做的方式，每个失败。有没有一个标准的方式解析这种类型的JSON？

I've tried many different ways of doing this, each failed. Is there a standard way for parsing json of this type?

推荐答案

您有对象不是字符串数组。创建一个映射属性的类和反序列化到了，

You have an array of objects not strings. Create a class that maps the properties and deserialize into that,

public class MyClass {
    public string id { get; set; }
    public string content { get; set; }
    public string ups { get; set; }
    public string downs { get; set; }
}

MyClass[] result = JsonConvert.DeserializeObject<MyClass[]>(download);

有只有少数基本类型的JSON，但它是有帮助的学习和识别它们。对象，数组，字符串等 http://www.json.org/ 和的 http://www.w3schools.com/json/default.asp 都是很好的资源开始。例如，一个字符串数组的JSON会是什么样子，

There are only a few basic types in JSON, but it is helpful to learn and recognize them. Objects, Arrays, strings, etc. http://www.json.org/ and http://www.w3schools.com/json/default.asp are good resources to get started. For example a string array in JSON would look like,

["One", "Two", "Three"]
