Question

my pattern is the following:

{(code)}
where code is a number (up to 6 digits), or 2 letter followed by a number.
For example:

{(45367)}
{(265367)}
{(EF127012)}

I want to find all occurrences in a long string, I can’t just use pure regex , because I need to preform some action when i find a match (like logging the position and the type of the match).

Answer 1

What you’re referring to doing can still be done with regular expressions. Try the following…

Regex regex = new Regex(@"\{\(([A-Z]{2}\d{1,6}|\d{1,6})\)\}");
String test = @"my pattern is the following:

I want to find all occurrences in a long string

var matches = regex.Matches(test);
foreach (Match match in matches)
{
    MessageBox.Show(String.Format("\"{0}\" found at position {1}.", match.Value, match.Index));
}

I hope that helps.
