我有一個需要發布到網關的 json 物件。它看起來如下。

{
  "client_id": "test",
  "non_personalized_ads": false,
  "events": [
    {
      "name": "test",
      "params": {
        "items": [
          {
            "itemitem1": "itemitem1value",
            "itemitem1number": 1
          }
        ],
        "stringparm1": "stringValue1",
        "intparm1": 1
      }
    }
  ]
}

我正在嘗試在我的 C# 專案中將其創建為物件類。問題是這些引數的名稱都是可配置的。所以這些都不是靜態屬性名稱。

• "itemitem1": "itemitem1 值",
• “專案 1 號”：1
• "stringparm1": "stringValue1",
• “intparm1”：1

因此，為了實作這一目標，我使用了 Dictionary<string, object>，因為值可以是數字或字串，我使用了 Object。

public class EventParameter
{
    public Dictionary<string, object> Parameters { get; set; }
    public Dictionary<string, object> Items { get; set; }
    public EventParameter()
    {
        Parameters = new Dictionary<string, object>();
        Items = new Dictionary<string, object>();
    }

    public void AddEventParameter(string name, object value)
    {
        Parameters.Add(name, value);
    }
}

不幸的是，當我對此進行 json 決議時，我得到了。這是不正確的，因為我的引數應該在 parms 下而不是在他們自己的物件下。

{
  "client_id": "test",
  "non_personalized_ads": false,
  "events": [
    {
      "name": "hit_event",
      "params": {
        "Parameters": {
          "TestString": "test",
          "testInt": 1
        },
        "Items": {
          "test": 1,
          "test2": 1,
          "test3": "test"
        }
      }
    }
  ]
}

那么如何讓引數上升到引數？感覺 parms 需要是一個 Dictionary<string, object> 但是它會丟失它的專案串列

 "Parameters": {
          "TestString": "test",
          "testInt": 1
        },

Im assuming there's something missing in my model design. I have been looking at this too long i cant come up with the solution. My other idea was could this be done by adding a custom json sterilizer?

Let me know if you want my full model design or the unit test I am using to test with.

unit test

[Fact]
public void Test1()
{

    var postData = new Event() { Name = "EventName" };
    postData.EventParameters.AddEventParameter("TestString", "test");
    postData.EventParameters.AddEventParameter("testInt", 1);
    postData.EventParameters.Items = new Dictionary<string, object>()
    {
        { "test", 1 },
        { "test2", 1 },
        { "test3", "test" },
    };
    
    var data = new EventData()
    {
        ClientId = "test",
        Events = new []
        {
            postData
        }
    };
    
    var options = new JsonSerializerOptions { IgnoreNullValues = true };
    var hold =JsonSerializer.Serialize(data);

    // add breakpoint here
    int i = 1;

}

這是一個序列化為您顯示的第一個 json 的類：

class X 
{
    public string client_id {get; set;}
    public bool non_personalized_ads {get; set;}

    public List<EventParameter> events { get;set;}
}

class EventParameter {
    public string name {get; set;}

    
    public Dictionary<string, object> @params {get; set;}
}

測驗代碼：

var x = new X 
{
    client_id = "test",
    non_personalized_ads = false,
    events = new List<EventParameter>{
        new EventParameter
        {
            name = "test1",
            @params = new Dictionary<string, object>{
                { "items", new Dictionary<string, object> {
                        {"itemitem1", "itemitem1value"},
                        {"itemitem1number", 1}
                    }},
                { "stringparm1", "stringValue1"},
                {"intparm1", 1}
            }
        }
    }
};

var json = System.Text.Json.JsonSerializer.Serialize(x, options: new System.Text.Json.JsonSerializerOptions{WriteIndented = true});
Console.WriteLine(json);

嘗試這個

    var events = JsonConvert.DeserializeObject<Root>(json);

測驗

json=JsonConvert.SerializeObject(events, Newtonsoft.Json.Formatting.Indented);

{
  "client_id": "test",
  "non_personalized_ads": false,
  "events": [
    {
      "name": "test",
      "params": {
        "items": [
          {
            "itemitem1": "itemitem1value",
            "itemitem1number": "1"
          }
        ],
        "stringparm1": "stringValue1",
        "intparm1": 1
      }
    }
  ]
}

班級

public class Root
{
    public string client_id { get; set; }
    public bool non_personalized_ads { get; set; }
    public List<Event> events { get; set; }
}

public class Event
{
    public string name { get; set; }
    public Params @params { get; set; }
}

public class Params
{
    public List<Dictionary<string, string>> items { get; set; }
    public string stringparm1 { get; set; }
    public int intparm1 { get; set; }
}
