如何在Firebase数据库Unity/C#中获得前5名的最高分？

using Firebase;
using Firebase.Database;
using Firebase.Unity.Editor;

void Start()
{
    // 设置Firebase数据库的URL
    FirebaseApp.DefaultInstance.SetEditorDatabaseUrl("YOUR_DATABASE_URL");
    
    // 获取数据库实例
    DatabaseReference reference = FirebaseDatabase.DefaultInstance.RootReference;
}

void GetTop5Scores()
{
    DatabaseReference reference = FirebaseDatabase.DefaultInstance.GetReference("scores");

    // 使用OrderByChild按照分数字段进行排序
    reference.OrderByChild("score").LimitToLast(5).GetValueAsync().ContinueWith(task =>
    {
        if (task.IsFaulted)
        {
            // 处理错误
        }
        else if (task.IsCompleted)
        {
            DataSnapshot snapshot = task.Result;
            
            // 遍历前5名的最高分数据
            foreach (DataSnapshot childSnapshot in snapshot.Children)
            {
                string playerName = childSnapshot.Key;
                int score = int.Parse(childSnapshot.Child("score").Value.ToString());
                
                // 在这里处理每个玩家的分数数据
            }
        }
    });
}
