Closed Atallah-Hammad closed 1 year ago

Atallah-Hammad commented 1 year ago

Hi, Are DateTime Functions working? DateDif(date1; date2; 'Y')?

If yes, Can give me an example

KovtunV commented 1 year ago

@Atallah-Hammad Hi, I believe yes, actually it should work as this but for "Y", "M", "D" only.

for example

static void Main()
{
    var eval = NoStringEvaluator.CreateFacade().Evaluator;

    var args = new Dictionary<string, EvaluatorValue>
    {
        { "date1", DateTime.Parse("01.01.2001") },
        { "date2", DateTime.Parse("01.01.2003") }
    };

    var res = eval.CalcNumber("DateDif(date1; date2; 'Y')", args); // 2
}
