使用ConcurrentDictionary多线程同步字典集合实例详解

var result = BLLFactory.Instance.FindFirst();
Console.WriteLine(result.ToJson());

            try{
                List list = new List();for (int i = 0; i <10; i++)
                {
                    Thread thread = new Thread(() =>{var result = BLLFactory.Instance.FindFirst();
                        Console.WriteLine(result.ToJson());
                        Console.WriteLine();
                    });

                    list.Add(thread);
                }for (int i = 0; i
