how do i use a class without instantiating it?
<p>I have class:</p>

<pre><code>static class GetRole
    {
        public static string OfUser(string username)
        {
            string result="None";
            foreach (string key in WebConfigurationManager.AppSettings)
            {
                if (WebConfigurationManager.AppSettings[key].Contains(username))
                {
                    result = WebConfigurationManager.AppSettings[key];
                    break;
                }
            }

            return result;
        }
    }
</code></pre>

<p>i would like to use it lik ethis</p>

<pre><code>string role = GetRole.OfUser(username);
</code></pre>

<p>or like this even better:</p>

<pre><code>string role = GetRole(username);
</code></pre>
