c# - How do I determine if a date lies between current week dates? -

in c#,

how check date in week dates?

eg: 6/02/2014

current weeks: 02/02/2014 - 08/02/2014

so dates in above week....

use check (last parameter optional if want 1 week fromdate, don't need use last parameter):

 public static bool dateinside(datetime checkdate,       datetime fromdate, datetime? lastdate = null)  {      datetime todate = lastdate != null ? lastdate.value : fromdate.adddays(6d);      return checkdate >= fromdate && checkdate <= todate;  } 

to call use:

bool isdateinside = dateinside(new datetime(2014, 02, 06),       new datetime(2014, 02, 02)); // return true 

and search first :) answer here: how check whether c# datetime within range

if want check if dates inside same week, can use this:

public static bool dateinsideoneweek(datetime checkdate, datetime referencedate) {     // first day of week actual culture info,      dayofweek firstweekday = system.globalization.cultureinfo.currentculture.datetimeformat.firstdayofweek;     // or can set want: firstweekday = dayofweek.monday;     // calculate first day of week reference date     datetime startdateofweek = referencedate;     while(startdateofweek.dayofweek != firstweekday)     { startdateofweek = startdateofweek.adddays(-1d); }     // fist day of week find, find last day of reference week     datetime enddateofweek = startdateofweek.adddays(6d);     // , check if checkdate inside period     return checkdate >= startdateofweek && checkdate <= enddateofweek; } 

actual week in culture info start monday, february 3th 2014 (so me week between february 3th , february 9th). if check date reference date (second parameter) today (2014-feb-06) results:

for 2014-feb-02 (sunday before week): false 2014-feb-03 (monday inside week): true 2014-feb-06 (today  inside week): true 2014-feb-09 (sunday inside week): true 2014-feb-10 (monday next        week): false 

you can call method check if 1 date inside same week referentional this:

dateinsideoneweek(new datetime(2014, 02, 02), new datetime(2014, 02, 06)); 

you can find current week start , end dates code:

datetime startdateofweek = datetime.now.date; // start actual date while(startdateofweek.dayofweek != dayofweek.monday) // set first day of week in country { startdateofweek = startdateofweek.adddays(-1d); } // after while loop first day of actual week datetime enddateofweek = startdateofweek.adddays(6d); // find last week day
