How to assert a text field contains in selenium c#
<p>I have this code I'm trying to assert that a text field contains "Post Published" I can't seem to figure it out</p>

<pre><code>string actualvalue = driver.FindElement(By.Id("message")).Text;

actualvalue.Contains("Post published1.");
</code></pre>

<p>I'm not sure where to place my assertion.</p>
