How can I check if a string contains another string in C#
<p>I have strings like this:</p>

<pre><code>var a = "abcdef  * dddddd*jjjjjjjjjjjjj";
var b = "aaaaaaaaaaaaaaaaaaaaaaaa * aaaaaa";
var c = "hhhhhhhhhhhhhhhhhhhhhhhhhhh";
</code></pre>

<p>Is there a smile way for me to check if the string contains a " * " within the first 20 characters?</p>
