ASP.NET Check if LoginName is null
<p>I have a web application on VS2005 C# and I would want to check if user is logged in the application.</p>

<p>Currently I am trying </p>

<pre><code>if (LoginName.Equals(null))
{
    Response.Redirect("/Project/Login.aspx");
}
</code></pre>

<p>but I seem to be getting some errors.</p>

<p>Anyone can tell me how I should do it or is there any better ways too check?</p>

<p>Thank you</p>

<hr>

<p>EDIT:</p>

<p>Sorry for being unclear with my question.</p>

<p><code>LoginName</code> is the <em>System.Web.UI.WebControls.LoginName</em>.</p>

<p>The error I am getting is `An object reference is required for the nonstatic field , method or property 'object.Equals(object)'</p>
