How to Deserialize a Mixed-Type JSON Array into a Strongly Typed C# Class?

Deserialize an array of values ​​with a fixed pattern to a strongly typed data class

Deserializing JSON data with a specific structure can present challenges, especially when dealing with mixed-type arrays. Here is the complete solution on how to use JSON.NET:

1. Mixed type array and dictionary

In this case, the players collection is indeed a dictionary with usernames as keys and an array of mixed types as values.

2. Unnamed values ​​in Player

Create a custom converter that reads the array of values ​​in the correct order, matching the expected properties on the Player class:

<code>public class ObjectToArrayConverter<T> : JsonConverter
{
    // ... 省略实现细节
}</code>

3. Custom Player class

Apply the converter to your Player class and use JsonPropertyAttribute.Order to specify the order of the properties:

<code>[JsonConverter(typeof(ObjectToArrayConverter<Player>))]
public class Player
{
    [JsonProperty(Order = 1)]
    public int UniqueID { get; set; }
    [JsonProperty(Order = 2)]
    public string PlayerDescription { get; set; }
    // ... 其他字段（根据需要）
}</code>

4. Root object

Create a strongly typed root object containing a dictionary of players:

<code>public class ScoreboardResults
{
    public int timestamp { get; set; }
    public int total_players { get; set; }
    public int max_score { get; set; }
    public Dictionary<string, Player> players { get; set; }
}</code>

5. Deserialize using Newtonsoft

<code>var results = JsonConvert.DeserializeObject<ScoreboardResults>(json);</code>
