    Add the number "1000000000" to the int, that would give you this; 1------------->10000000001 345----------->10000000345 65576--------->10000065576 Now, convert them to a string, and loose the first character. That would give you these strings; 10000000001------------->0000000001 10000000345------------->0000000345 10000065576------------->0000065576 Enjoy :)

    Interresting solution. I overlooked that one. :)

        :omg: Not the most elegant and simple, obvious. It's just a fun question that has lots of possible solutions. Some solutions even make code-obfuscation irrelevant :laugh:

          There are many, many ways... What you want to do according to your question: "00000" + number.ToString() or number.ToString("'00000'0") or string.Format("'00000'{0}", number) or new String('0', 5) + number.ToString() or number.ToString().Insert(0, "00000") What you want to do according to your examples: String.Format("{0:0000000000}", number) or number.ToString("0000000000") or number.ToString().PadLeft(10, '0')

              There sure are some interresting solutions. Here's an almost completely useless way of doing it: String.Join(null,number.ToString().ToCharArray().Reverse().Select(c=>c.ToString()).Concat(new int[10].Select(i=>i.ToString())).Take(10).Reverse().ToArray()) ;)

                Then it would probably have been a more hardcore solution: char[] c = new char[10]; for (int i = 9; i >= 0; number /= 10) c[i--] = (char)('0' + number % 10); string result = new String(c); ;)

                    LINQ! :-D I haven't done much with Linq yet, but I'll take the time for it this weekend. It's turning up at more and more places, and most people agree that it's a good thing. ..and that would be a better idea than to write a recursive method to padd zeroes, wouldn't it? :laugh:

                      Noes, I learned it in "Amos Basic", using GWBasic examples :-\ It's been over fifteen years, and there are still days that I'm having trouble with even the most basic statement :laugh:

                          wow long time huh... :) I have started with QBasic. But I still remember those college days when in exams they ask some silly things like. *) write a function to swap 2 variables without using 3rd one or references. *) draw a pascal triangle without using array (recurrsion : damn thing) X|

                            Things haven't changed much, my roommate is in college and learning C# using the book "Head First C#". It's got some basic examples as to be expected, and they're gonna build two games during class. One arcade-type, another rpg-type. It looks better when you see the graphics, but is just as much fun as doing a Snakes-game in basic :-D ..and yeah, I do miss those logical puzzles from school sometimes. I don't miss being sent out of class though :suss:

                              No, that wasn't assembly code. If inline asm was supported, it might look more like this:

                              string result;
                              unsafe {
                              char* p = stackalloc char[10];
                              asm {
                              lea esi, number
                              mov eax, [si]
                              lea edi, p
                              add edi, 014
                              std
                              mov cx, 0a
                              .digit
                              xor edx, edx
                              div dword 0a
                              xchg eax, edx
                              add ax, 030
                              stosw
                              xchg eax, edx
                              loop digit
                              }
                              result = new String(c);
                              }

                              :)
