I'm writing a service but I want to have config settings to make sure that the service does not run within a certain time window on one day of the week. eg Mondays between 17:00 and 19:00.
Is it possible to create a datetime that represents any monday so I can have one App config key for DontProcessStartTime and one for DontProcessEndTime with a values like "Monday 17:00" and "Monday 19:00"?
Otherwise I assume I'll have to have separate keys for the day and time for start and end of the time window.
Any thoughts?
thanks
You could use a utility that will parse your weekday text into a System.DayOfWeek enumeration, example here . You can then use the Enum in a comparison against the DateTime.Now.DayOfWeek
You can save the day of the week and start hour and endhour in your config file, and then use a function similar to the following:
public bool ShouldRun(DateTime dateToCheck)
{
//These should be read from your config file:
var day = DayOfWeek.Monday;
var start = 17;
var end = 19;
return !dateToCheck.DayOfWeek == day &&
!(dateToCheck.Hour >= start && dateToCheck.Hour < end);
}
You can use DayOfTheWeek
property of the DateTime
. And to check proper time you can use DateTime.Today
(returns date-time set to today with time set to 00:00:00) and add to it necessary amount of hours and minutes.
This is very rough code, but illustrates that you can check a DateTime object containing the current time as you wish to do:
protected bool IsOkToRunNow()
{
bool result = false;
DateTime currentTime = DateTime.Now;
if (currentTime.DayOfWeek != DayOfWeek.Monday && (currentTime.Hour <= 17 || currentTime.Hour >= 19))
{
result = true;
}
return result;
}
The DateTime
object cannot handle a value that means all mondays. It would have to be a specific Monday. There is a DayOfWeek
enumeration. Another object that may help you is a TimeSpan
object. You could use the DayOfWeek
combined with TimeSpan
to tell you when to start, then use another TimeSpan
to tell you how long
