title: Can I add a regular expression into a .Net Assertion?
body: <p>I'm trying to pull out page source from a set of pages and run an assertion on the results, this is a Test that runs to check that we are crawling specific pages in our site.  Sometimes the results come back with a different case for the URL string, I'd like to account for that in the Assertion where I am checking page source.  This is probably the wrong way to do this but I was wondering if there is a way to add in the .Net regex commands to the Assertion text.  I have this as an assertion:</p>
  
  <pre><code>Assert.IsTrue(driver.PageSource.Contains("/explore"));
  </code></pre>
  
  <p>But is there a way to be sure that I can capture explore, Explore or EXPLORE?  I though I could use (?i) here but that doesn't seem to work.  I'm more used to Perl and it's regex capabilities but with C# and .Net I'm a little lost on where I can and can't use the inline regex commands.</p>
