title: Does RegEx a* match all strings?
body: <p>I have the following code:</p>
  
  <pre><code>string rex = "a*";
  string txt = "cvb";
  Regex regex = new Regex(rex);
  Console.WriteLine("Success:" + regex.IsMatch(txt));
  </code></pre>
  
  <p>This code is returning <strong>true</strong> always.
  I thought that a pattern a* will ONLY match: "" , "a", "aa", "aaa....".</p>
  
  <p>I tested this situation <a href="http://www.regexplanet.com/simple/" rel="nofollow">here</a>.</p>
  
  <p>And the same example did not match.</p>
