c# find in text something or something

Question

I need to search in text, but is it possible to have more than one option in richtextbox.Find("something");? For example richtextbox.Find("something" or "somethingelse");

Answer 1

You can implement something like this (an extension method FindAny for RichTextBox):

  public static class RichTextBoxExtensions {
    public static int FindAny(this RichTextBox source, params String[] toFind) {
      if (null == source)
        throw new ArgumentNullException("source");
      else if (null == toFind)
        throw new ArgumentNullException("toFind");

      int result = -1;

      foreach (var item in toFind) {
        if (null == item)
          continue;

        int v = source.Find(item);

        if ((v >= 0) && ((result < 0) || (v < result)))
          result = v;
      }

      return result;
    }
  }

....

  int result = richtextbox.FindAny("something", "somethingelse");
