adding 48 to string number
<p>I have a string in C# like this:</p>

<pre><code>string only_number;
</code></pre>

<p>I assigned it a value = <code>40</code></p>

<p>When I check <code>only_number[0]</code>, I get <code>52</code><br>
When I check <code>only_number[1]</code>, I get <code>48</code></p>

<p>why it is adding 48 to a character at current position? Please suggest</p>
