Find a char in a List of Strings

Question

I'm looking for a smart way to find List-Elements with a specific Character in a List of Strings.

I want to find all Strings, wich contains a ?-sign in a List of Strings like: "a?11", "ab12", "bb12", "b?13"

My current solution looks like this:

// Interates through all strings.
foreach (string currentString in listOfStrings)
{
  if (currentString.Contains('?'))
  {
    // Found!
    myStrings.Add(currentString);
  }
}

Is there a better way to do this job, maybe like:

List<string> myStrings = listOfStrings.Select(z => z.Contains('?')).ToList();

Any ideas?

better is extremely relative. I'd try codereview.SE. – Sam Axe Mar 20 '13 at 22:13 — Sam Axe, Mar 20 '13 at 22:13

Simple as it is. :) I tryed FindAll instead of Where and it works too. Are there any differences? Thank you very much! – Christoph Brückmann Mar 20 '13 at 22:26
