Returning a new value
<p>I have write a function but this function still returns me the old string in stead of the new one. I don't know how to return a new string when you did something with the old one</p>

<p>By example:</p>

<pre><code>public string TestCode(string testString)
{

// Here something happens with the testString


//return testString; &lt;-- i am returning still the same how can i return the new string //where something is happened with in the function above

}
</code></pre>
