lock Dictionary 对象中的项能否达到预期

public static class Demo

    {

        private static Dictionary<string, int> typeData = new Dictionary<string, int>();

        private static Dictionary<string, object> lockHelper = new Dictionary<string, object>();



        static Demo()

        {

            List<string> configData = new List<string>() { "test1", "test2" }; //从配置文件中获取的，运行时项不会有变动

            foreach (var data in configData)

            {

                typeData.Add(data, 0);

                lockHelper.Add(data, new object());

            }

        }



        static void Work(string typeKey)

        {

            if (typeData.ContainsKey(typeKey) == false) return;



            lock (lockHelper[typeKey])

            { 

                //执行一些相同的操作，比如

                typeData[typeKey] = typeData[typeKey] + 3;

            }

        }

    }
