Hello everyone,

I have a string that has a "/" in the middle of it. Either side of this character there are numbers, but this string can change size at any time, but there is always a "/" in the middle of it.

I need to find the number of characters before the "/" and the number of characters after the "/".

The maximum number of characters before the "/" is 4, and the maximum number of characters after the "/" is 2.

I need to see if the number of characters in the first part of the string is 4, if it isn't, I need to add however many zero's to the start of it to make it 4 characters long.

Then I need to see if the number of characters in the second part of the string is 2, if it isn't, I need to add a zero to the start of that part of the string.

Any help is greatly appreciated,
thanks.

I think a regular expression to extract both parts would do the trick here :

C#

Regex regex = new Regex(@"^(?<LeftPart>[\d]?)/(?<RightPart>[\d]?)$", RegexOptions.Compiled | RegexOptions.IgnoreCase);
Match m = regex.Match(yourString);

if (m.Success)
{
   string left = m.Groups["LeftPart"].Value;
   string right = m.Groups["RightPart"].Value;

   while (left.Length < 4)
      left.Insert(0, "0");

   while (right.Length < 2)
      right.Insert(0, "0");
}
else
{
   // Handle error
}

Hope this helps.
Regards.
