如何在C#中创建unix时间戳？(例如2012-10-10 14:00:00 - > 1349877600)

Answer 1

private double ConvertToTimestamp(DateTime value)
{
    //create Timespan by subtracting the value provided from
    //the Unix Epoch
    TimeSpan span = (value - new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime());

    //return the total seconds (which is a UNIX timestamp)
    return (double)span.TotalSeconds;
}
