使用 C# 将字符串转换为 json

Question

我是C#的初学者，我有一个很长的字符串，想把它转换成json，字符串是

{"employees":
[{"id":0,"level":0,"label":"Product Names","subitems":
    [{"id":0,"level":1,"label":"Soren","subitemslevel3":
        [{"id":0,"level":2,"label":"AAAA"},{"id":0,"level":2,"label":"bbb"}]},
{"id":0,"level":1,"label":"Test","subitemslevel3":
        [{"id":0,"level":2,"label":"111"},{"id":0,"level":2,"label":"2222"}]}]},
\

有什么想法吗？

Answer 1

你可以这样做：

var jobject = JsonConvert.DeserializeObject<JObject>(yourVariable);

这是使用 Newtonsoft 的 json 库，您可以从 nuget 获得。

JObject 也是 JSON 对象的 C# 等价物，所以这可能是您想要使用的东西。

Answer 2

你也可以使用，

JObject.Parse(urJsonString);

JObject 位于 Newtonsoft.Json.Linq 命名空间中。

Answer 3

您需要按如下方式反序列化您的字符串：

// Your string here 
string str = @"[{"categories":
[{"id":0,"level":0,"label":"Product Names","subitems":
    [{"id":0,"level":1,"label":"Soren","subitemslevel3":
        [{"id":0,"level":2,"label":"AAAA"},{"id":0,"level":2,"label":"bbb"}]},
{"id":0,"level":1,"label":"Test","subitemslevel3":
        [{"id":0,"level":2,"label":"111"},{"id":0,"level":2,"label":"2222"}]}]},
{"id":0,"level":0,"label":"Product texts","subitems":
    [{"id":0,"level":1,"label":""},{"id":0,"level":1,"label":"<p>Disney <strong>Princess<\/strong><\/p>\n"},{"id":0,"level":1,"label":"<p>Machines & Mechanisms - <strong>Middle<\/strong><\/p>\n"},{"id":0,"level":1,"label":"64738574"},{"id":0,"level":1,"label":"8765432"},{"id":0,"level":1,"label":"a"},{"id":0,"level":1,"label":"aa"},{"id":0,"level":1,"label":"ab"},{"id":0,"level":1,"label":"abe"},{"id":0,"level":1,"label":"aD!?"},{"id":0,"level":1,"label":"Bionicle"},{"id":0,"level":1,"label":"Disney Princess"},{"id":0,"level":1,"label":"er"},{"id":0,"level":1,"label":"foo foo"},{"id":0,"level":1,"label":"hej"},{"id":0,"level":1,"label":"igen"},{"id":0,"level":1,"label":"meta"},{"id":0,"level":1,"label":"metadata"},{"id":0,"level":1,"label":"metadata from kafka"},{"id":0,"level":1,"label":"Metatest"},{"id":0,"level":1,"label":"q"},{"id":0,"level":1,"label":"Simpsons"},{"id":0,"level":1,"label":"test"},{"id":0,"level":1,"label":"Test 123"},{"id":0,"level":1,"label":"Test Metadata 123"}]},{"id":0,"level":0,"label"      :"Specialist Terms","subitems":[{"id":0,"level":1,"label":"meta"},{"id":0,"level":1,"label":"new category 1111"},{"id":0,"level":1,"label":"secret category"}]}]}]";

// DeSerialize your object 
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize(str, obj1.GetType());
