You can solve your problem like below bunch of codes

<pre><code>public class Response
{
 public string loopa { get; set; }
 public string drupa{ get; set; }
 public Image[] images { get; set; }
}

public class RootObject&lt;T&gt;
 {
 public List&lt;T&gt; response{ get; set; }

 }

var des = (RootObject&lt;Response&gt;)Newtonsoft.Json.JsonConvert.DeserializeObject(Your JSon String, typeof(RootObject&lt;Response&gt;));

blocks|key|1699697|text|我还遇到了在C#中解析和使用JSON对象的问题。我用一些库检查了动态类型，但问题总是检查属性是否存在。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1699698|最后，我偶然发现了this+web+page，这为我节省了很多时间。它会根据您的JSON数据自动创建一个强类型的类，您将在Newtonsoft库中使用它，并且它可以完美地工作。它还可以与C#以外的语言一起使用。|offset|length|1699699|entityMap|0|LINK|mutability|MUTABLE|url|https://app.quicktype.io/#l=cs&r=json2csharp^0|0|9|D|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

I also had the issue of parsing and using JSON objects in C#. I checked the dynamic type with some libraries, but the issue was always checking if a property exists.

In the end, I stumbled upon <a href="https://app.quicktype.io/#l=cs&amp;r=json2csharp" rel="nofollow noreferrer">this web page</a>, which saved me a lot of time. It automatically creates a strongly typed class based on your JSON data, that you will use with the Newtonsoft library, and it works perfectly. It also works with languages other than C#.

blocks|key|1913210|text|您可以使用nuget包Newtonsoft.JSON来实现这一点：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1913211|JsonConvert.DeserializeObject<List<Response>>(yourJsonString)|code-block|syntax|javascript|1913212|entityMap^0|B|F|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

You could use the nuget package <code>Newtonsoft.JSON</code> in order to achieve this:

<pre class="lang-cs prettyprint-override"><code>JsonConvert.DeserializeObject&lt;List&lt;Response&gt;&gt;(yourJsonString)
</code></pre>

I have a JSON string and I need some help to deserialize it.

Nothing worked for me... This is the JSON:

<pre><code>{
 "response": [{
 "loopa": "81ED1A646S894309CA1746FD6B57E5BB46EC18D1FAff",
 "drupa": "D4492C3CCE7D6F839B2BASD2F08577F89A27B4ff",
 "images": [{
 "report": {
 "nemo": "unknown"
 },
 "status": "rock",
 "id": "7e6ffe36e-8789e-4c235-87044-56378f08m30df",
 "market": 1
 },
 {
 "report": {
 "nemo": "unknown"
 },
 "status": "rock",
 "id": "e50e99df3-59563-45673-afj79e-e3f47504sb55e2",
 "market": 1
 }
 ]
 }]
}
</code></pre>

I have an example of the classes, but I don't have to use those classes. I don't mind using some other classes.

These are the classes:

<pre><code>public class Report
{
 public string nemo { get; set; }
}

public class Image
{
 public Report report { get; set; }
 public string status { get; set; }
 public string id { get; set; }
 public int market { get; set; }
}

public class Response
{
 public string loopa { get; set; }
 public string drupa{ get; set; }
 public Image[] images { get; set; }
}

public class RootObject
{
 public Response[] response { get; set; }
}
</code></pre>

I want to mention that I have Newtonsoft.Json already, so I can use some functions from there.

How can I do this?
