Why compile error “Use of unassigned local variable”?

Question

My code is the following

int tmpCnt;  
if (name == \"Dude\")  
   tmpCnt++;  

Why is there an error Use of unassigned local variabl

Answer 1

IEnumerable _getCurrentHolidayList; //this will not initailize

Assign value(_getCurrentHolidayList) inside the loop

foreach (HolidaySummaryList _holidayItem in _holidayDetailsList)
{
                            if (_holidayItem.CountryId == Countryid)
                                _getCurrentHolidayList = _holidayItem.Holiday;                                                   
}

After your are passing the local varibale to another method like below. It throw error(use of unassigned variable). eventhough nullable mentioned in time of decalration.

var cancelRescheduleCondition = GetHolidayDays(_item.ServiceDateFrom, _getCurrentHolidayList);

if you mentioned like below, It will not throw any error.

IEnumerable _getCurrentHolidayList =null;
