Adding variable to string in ASP.net
<p>Ok, so it's easy in VB, but I can't figure it out in C#:</p>

<pre><code>SqlCommand cmd = new SqlCommand("SELECT COUNT(*) FROM tblUsers WHERE username = '" &amp; username &amp; "'", cn);
</code></pre>

<p>This throws</p>

<pre><code> CS0019: Operator '&amp;' cannot be applied to operands of type 'string' and 'string'
</code></pre>

<p>Googled it and can't find an answer, help this newbie here please!</p>
