Why use a GlobalClass? What are they for?
<p>Why use a GlobalClass? What are they for? I have inherited some code (shown below) and as far as I can see there is no reason why strUserName needs this. What is all for?</p>

<pre><code>public static string strUserName
    {
        get { return m_globalVar; }
        set { m_globalVar = value; }
    }
</code></pre>

<p>Used later as:</p>

<pre><code>GlobalClass.strUserName
</code></pre>

<p>Thanks</p>
