I have string "1999220" how to parse?
-
I have develop simple application first I take birthday from user and calculate his lucky number from sum of the values of the birthday Ex: '19881205' How i get the sum of values in this string?
Use one of the integer methods[^] to parse it into a number and then use the Digital root method[^]. Alternatively extract each character one at a time, and sum the integer values.
Use the best guess

Long winded, but as a demo...
static void SumNumbersinDate()
{
//http://www.codeproject.com/Messages/4513781/I-have-string-1999220-how-to-parse.aspx
string theDate = "19881205";
char[] dateLetters = theDate.ToCharArray();
int[] dateNumbers = new int[theDate.Length];
int sum = 0;
for (int ind = 0; ind < theDate.Length; ind++)
{
Console.WriteLine("Current Total: " + sum.ToString());
dateNumbers[ind] = int.Parse(dateLetters[ind].ToString());
Console.WriteLine("Adding: " + dateNumbers[ind].ToString());
sum += dateNumbers[ind];
Console.WriteLine("New Total: " + sum.ToString());
}
Console.WriteLine("The sum of the numbers is: " + sum.ToString());
Console.WriteLine("Press any key to close the demo...");
Console.ReadKey(true);

Integer.TryParseis often the best solution since it ensures you are parsing an integer and if not, does not throw an error.WP Apps - Color Search | Arctic | XKCD | Sound Meter | Speed Dial

Do you also have to verify that a date is valid? I'd hazard a guess that maybe you should. Garbage-In = Garbage-Out
Q. Hey man! have you sorted out the finite soup machine? A. Why yes, it's celery or tomato.
Since OP needs this to calculate a "lucky number" I wouldn't worry too much about "garbage". ;)
