                  问题描述

                  限时送ChatGPT账号..

                  我有一些像这样的 JSON

                  I have some JSON that looks like this

                  [
                    {
                      "MobileSiteContent": {
                        "Culture": "en_au",
                        "Key": [
                          "NameOfKey1"
                        ]
                      }
                    },
                    {
                      "PageContent": {
                        "Culture": "en_au",
                        "Page": [
                          "about-us/"
                        ]
                      }
                    }
                  ]
                  

                  我将其解析为 JArray:

                  I parse this as a JArray:

                  var array = JArray.Parse(json);
                  

                  然后,我循环遍历数组:

                  Then, I loop over the array:

                  foreach (var content in array)
                  {
                  
                  }
                  

                  content 是一个 JToken

                  如何检索每个项目的名称"或密钥"?

                  How can I retrieve the "name" or "key" of each item?

                  例如,MobileSiteContent"或PageContent"

                  For example, "MobileSiteContent" or "PageContent"

                  推荐答案

                  JTokenJObject, JArray, 的基类>JPropertyJValue 等.您可以使用 Children<T>() 方法获取某个 JToken 的子代的过滤列表类型,例如 JObject.每个 JObject 都有一个 JProperty 对象的集合,可以通过 Properties() 方法访问这些对象.对于每个 JProperty,您可以获得它的 Name.(当然你也可以根据需要获取Value,也就是另一个JToken.)

                  JToken is the base class for JObject, JArray, JProperty, JValue, etc. You can use the Children<T>() method to get a filtered list of a JToken's children that are of a certain type, for example JObject. Each JObject has a collection of JProperty objects, which can be accessed via the Properties() method. For each JProperty, you can get its Name. (Of course you can also get the Value if desired, which is another JToken.)

                  综合起来我们有:

                  JArray array = JArray.Parse(json);
                  
                  foreach (JObject content in array.Children<JObject>())
                  {
                      foreach (JProperty prop in content.Properties())
                      {
                          Console.WriteLine(prop.Name);
                      }
                  }
                  

                  输出:

                  MobileSiteContent
                  PageContent
