Console.WriteLine("String format number leading zero: " + string.Format("{0:D6}", number)); //dynamically determine number length and format string. Console.WriteLine("\nAnother dynamic option: " + number.ToString(dValue)); //another technique to format string using padleft method. Console.WriteLine("Another technique: " + number.ToString().PadLeft(length, '0')); Console.ReadLine(); } } |
Output:
1 2 3 4 5 6 7 8 9 | formatted string.............. Number: 12345 String format number leading zero: 012345 String format number leading zero: 012345 Another dynamic option: 012345 Another technique: 012345 |
