如何找到从数组到DateTime.Now的最接近的较大时间

Question

I am trying to find closest bigger time to current time. This is the code that i have:

var busTimes = new string[]
    {
        "15:00",
        "16:00",
        "17:00",
        "18:00",
        "19:00",
        "20:00",
        "21:00"
        }
        .Select(x => DateTime.Parse(x))
        .ToList();

var now = DateTime.Now.TimeOfDay;

var closestTime = (from x in busTimes
                   where x.busTimes.TimeOfDay > now
                   orderby x.busTimes.TimeOfDay ascending
                   select x).First(); 

But I get this error:

Error CS1061 'DateTime' does not contain a definition for 'busTimes' and no extension method 'busTimes' accepting a first argument of type 'DateTime' could be found (are you missing a using directive or an assembly reference?)

How can i fix this?

Answer 1

x is a DateTime , like the error message said, there is no busTimes property on it.

var closestTime = (from x in busTimes
    where x.TimeOfDay > now
    orderby x.TimeOfDay ascending
    select x).First(); 

Answer 2

Your query should be:

var closestTime = (from x in busTimes
        where x.TimeOfDay > now
        orderby x.TimeOfDay ascending
        select x).First(); 

As the x identifier represents a DateTime and a DateTime struct doesn't have a 'busTimes' property.
