【.NET】 C# 时间戳和DataTime 互相转换

1 System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); // 当地时区
2 long timeStamp = (long)(DateTime.Now - startTime).TotalSeconds; // 相差秒数
3 System.Console.WriteLine(timeStamp);

1 long unixTimeStamp = 1478162177;
2 System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1)); // 当地时区
3 DateTime dt = startTime.AddSeconds(unixTimeStamp);
4 System.Console.WriteLine(dt.ToString("yyyy/MM/dd HH:mm:ss:ffff"));
