<p>I have a variable :</p>

<pre><code>string variable1;
</code></pre>

<p>And I'm trying to make something like this :</p>

<pre><code>for (int i = 0; i &lt; 299; i += 2)
        {
            variable1 = variable1 &amp;&amp; IntToHex(buffer[i]);
        }
</code></pre>

<p>IntToHex is a string function, so the result of the "IntToHex(buffer[i])" will be string. But it comes up to an error saying I cannot use &amp;&amp;. Is there any solution to add a string to another string? Thanks!</p>
