.indexOf for multiple results

Question

Let\'s say I have a text and I want to locate the positions of each comma. The string, a shorter version, would look like this:

string s = \"A lot, of text,          


        

Answer 1

You could use Regex.Matches(string, string) method. This will return a MatchCollection and then you could determine the Match.Index. MSDN has a good example,

using System; using System.Text.RegularExpressions;

public class Example
{
   public static void Main()
   {
      string pattern = @"\b\w+es\b";
      string sentence = "Who writes these notes?";

      foreach (Match match in Regex.Matches(sentence, pattern))
         Console.WriteLine("Found '{0}' at position {1}", 
                           match.Value, match.Index);
   }
}
// The example displays the following output:
//       Found 'writes' at position 4
//       Found 'notes' at position 17
