如何将Unix时间戳转换为DateTime，反之亦然？

这是您需要的：

public static DateTime UnixTimeStampToDateTime( double unixTimeStamp ){    // Unix timestamp is seconds past epoch    System.DateTime dtDateTime = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);    dtDateTime = dtDateTime.AddSeconds( unixTimeStamp ).ToLocalTime();    return dtDateTime;}

或者，对于Java（这是不同的，因为时间戳以毫秒为单位，而不是秒）：

public static DateTime JavaTimeStampToDateTime( double javaTimeStamp ){    // Java timestamp is milliseconds past epoch    System.DateTime dtDateTime = new DateTime(1970,1,1,0,0,0,0,System.DateTimeKind.Utc);    dtDateTime = dtDateTime.AddMilliseconds( javaTimeStamp ).ToLocalTime();    return dtDateTime;}
