在 C# 中從多個數組對象創建單個對象數組

Question

我有一個像下面這樣的 Web API 響應，我需要將所有對象移動到 C# ASP.NET 中的單個數組中

[
   [
      {
         "id":23,
         "name":"John",
         "email":"John@domain.com",
         "appointment_date":"tomorrow",
         "appointment_category":3,
         "time":"morning"
      },
      {
         "id":35,
         "name":"John",
         "email":"John@domain.com",
         "appointment_date":"tomorrow",
         "appointment_category":4,
         "time":"afternoon"
      }
   ],
   [
      {
         "id":17,
         "name":"Alex",
         "email":"Alex @domain.com",
         "appointment_date":"tomorrow",
         "appointment_category":3,
         "time":"morning"
      }
   ],
   [
      {
         "id":22,
         "name":"Bob",
         "email":"Bob@domain.com",
         "appointment_date":"tomorrow",
         "appointment_category":5,
         "time":"morning"
      }
   ]
]

我想將所有對象移動到單個數組中。 像下面

[
   {
      "id":23,
      "name":"John",
      "email":"John@domain.com",
      "appointment_date":"tomorrow",
      "appointment_category":3,
      "time":"morning"
   },
   {
      "id":17,
      "name":"John",
      "email":"John@domain.com",
      "appointment_date":"tomorrow",
      "appointment_category":3,
      "time":"morning"
   },
   {
      "id":17,
      "name":"John",
      "email":"John@domain.com",
      "appointment_date":"tomorrow",
      "appointment_category":3,
      "time":"morning"
   }
]

請幫助我謝謝你

Answer 1

不確定您是否已經反序列化了 json。 但是你可以這樣做。 創建 2 個類並使用 Newtonsoft.Json 進行反序列化。 然后使用帶有SelectMany Linq來獲取單個對象的列表。

//deseralize the json
var list1 = JsonConvert.DeserializeObject<List<List<Class2>>>(json);

//select all the nested items
var list2 = list1.SelectMany(x => x).ToList();

班級

public class Class1
{
    public List<Class1> list { get; set; }
}


public class Class2
{
    public int id { get; set; }
    public string name { get; set; }
    public string email { get; set; }
}
