mysql数据Unix时间戳与C# DateTime时间类型互换

Unix时间戳最小单位是秒,开始时间为格林威治标准时间1970-01-01 00:00:00
ConvertIntDateTime方法的基本思路是通过获取本地时区表示Unixk开始时间,加上Unix时间值(即过去的秒数).
ConvertDateTimeInt方法的基本思路是通过刻度数差,再把刻度数转换为秒数,当然要说明的是,我这里返回的是double类型,意义上并非是真正的Unix时间戳格式。
要获取真正Unix时间戳的,只获取整数部分就可以了。

        /// <param name="d">double 型数字</param>
        /// <returns>DateTime</returns>
        public static System.DateTime ConvertIntDateTime(double d)
        {
             System.DateTime time = System.DateTime.MinValue;
             System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1));
             time = startTime.AddSeconds(d);
            return time;
         }
