I have a function that converts a given date to timestamp. the date format is dynamic. for example (it could be 'dd/MM/yyyy' or 'dd-MM-yyyy' or MM/dd/yyyy).but date format is also passed as an argument in the function. i need to seperate day , month and year for this conversion. how can i separate as given in formation string

 public static double GetTimeStamp(string date, string format)
 
 string[] dateToConvert = date.Split('/');

 int year=Int32.Parse(dateToConvert[2]);
 int month=Int32.Parse(dateToConvert[1]);
 int day=Int32.Parse(dateToConvert[0]);

 var baseDate = new DateTime(1970, 01, 01);
 var toDate = new DateTime(year, month, day);
 var numberOfSeconds = toDate.Subtract(baseDate).TotalSeconds;
 return numberOfSeconds;
 

i am using '/' as a separation character. but i want to separate it as provided in the formation. if formation string is (dd-MM-yyyy). i need to seperate it using '-' charecter

c# date

  One other note: you can subtract a DateTime from another DateTime. This will result in a TimeSpan object. That type has a Seconds property. It would simplify your calculation

  To extract the year, month, and day, you can use the relevant properties: int year = dateTime.Year int month = dateTime.Month int day = dateTime.Day This avoids creating strings just to read them back into ints again. To get just the date component you can use: var toDate = dateTime.Date which returns a copy of dateTime with all the time information stripped (set to zero).
