            // 指定自定义格式字符串以适应字符串的组成
            string formatString = "yyyy-MM-dd HH:mm:ss,fff";

            // 使用自定义格式解析字符串
            DateTime myDate = DateTime.ParseExact("2009-05-08 14:40:52,531", formatString, CultureInfo.InvariantCulture);

            // 输出解析的日期
            Console.WriteLine(myDate.ToString()); // 显示 2009-05-08 14:40:52,531
