How to use ? character in an enum
<p>I work in C#, Visual Studio '05... In my enum, how can I use  the <code>'?'</code> character? My enum is
below:</p>

<pre><code>public enum Questions
{
    How_old_are_you?_= 0,//How to set the ? character 
    What_is_your_name= 1
}
</code></pre>

<p>After I add  the <code>'?'</code> character there are some errors.</p>
