請教一個關於LCObject.Save帶query的平行度問題

[QQtun]

C# .net core 3.1
這段程式碼實際上有幾個Save是可以成功的?

        var obj = LCObject.Create("Test");
        obj["count"] = 0;
        await obj.Save();

        async Task Save(int count)
        {
            var obj2 = LCObject.CreateWithoutData("Test", obj.ObjectId);
            obj2["count"] = count;
            var condition = new LCQuery<LCObject>("Test");
            condition.WhereEqualTo("count", 0);
            await obj2.Save(true, condition);
            // 有幾個能成功Save ??
        }

        var tasks = new List<Task>();
        for (int i = 0; i < 5; i++)
        {
            tasks.Add(Save(i + 1));
        }

        await Task.WhenAll(tasks);

大量同時對同一物件做有條件的Save時 這樣的寫法能保證只有一個Save會成功嗎?
