Question

我已将数据存储在Parse中，现在我必须访问它才能为玩游戏的用户创建topTen分数，从而允许用户只显示在列表中。存储数据使得每个游戏具有一个具有名称，传递等用户的会话。

所以它是Run Session =＆gt;用户（姓名，通行证，电子邮件等）。

我需要访问用户的名称，以检查用户是否已经出现在topTen上并显示名称。

虽然我可以访问会话中的数据，但我无法访问用户的数据。

        int counter = 0;

    ParseQuery<ParseObject> query = ParseObject.GetQuery("Runs").WhereEqualTo("scoreIdentifier", GameController.instance.scoreContext).OrderByDescending("score");
    query.Include("session.user");
    query.FindAsync().ContinueWith(t => {
        IEnumerable<ParseObject> results = t.Result;
        foreach (var item in results) {
            if (item.ContainsKey("score")) {
                if (counter < 10) {
                    topTenScores[counter] = item.Get<int>("score");
                    topTenNames[counter] = item.ObjectId;
                    ParseObject session = item.Get<ParseObject>("session");
                    Task<ParseObject> user = session.FetchAsync<ParseObject>();

                    user.ContinueWith(tt => {
                        ParseObject userName = tt.Result;
                        Debug.Log("CHECK FOR TT " + tt.Result.ObjectId);
                    });
                }
                if (counter == 9) {
                    updateTopTen = true;
                }
                counter++;
            }
            if (counter < 10)
                updateTopTen = true;
        }
    });

tt.Result.ObjectId为Session写出了objectId，而我认为它适用于User。

关于我做错了什么的任何建议？

我自己想出来了 - fetchAync（）需要多次迭代：

public void TopTenHighScore() {
    int sessionCounter = 0;

    ParseQuery<ParseObject> query = ParseObject.GetQuery("Runs").WhereEqualTo("scoreIdentifier", GameController.instance.scoreContext).OrderByDescending("score");
    query.Include("session.user");
    query.FindAsync().ContinueWith(t => {
        IEnumerable<ParseObject> results = t.Result;
        foreach (var item in results) {
            if (item.ContainsKey("score")) {
                if (sessionCounter < 10) {
                    // --- this is for the overall Score
                    topTenScores[sessionCounter] = item.Get<int>("score"); 

                    ParseObject sessionPointer = item.Get<ParseObject>("session");
                    Task<ParseObject> session = sessionPointer.FetchAsync<ParseObject>();  

                    session.ContinueWith(tt => {
                        ParseObject userPointer = tt.Result;                            
                       Task<ParseObject> user = userPointer.Get<ParseObject>("user").FetchAsync<ParseObject>();

                       user.ContinueWith(ttt => {
                           ParseObject userFinal = ttt.Result;
                           userNamesList.Add(userFinal.Get<string>("displayName"));
                       });
                    });
                }
                if (sessionCounter == 9) {
                    sessionCounterDone = true;
                }
                sessionCounter++;
            }
            // if the amount of sessions played in total is not above 10
            if (sessionCounter < 10)
                sessionCounterDone = true;
        }
    });
}

在c＃中解析Parse中指针的两个级别
