error type or namespace name profilecommon could not be found
<p>When I compile this code, It show me this kind of error type or namespace name profilecommon could not be found. Could someone help me how to solve this?</p>

<pre><code>case "Profile":
ProfileCommon pc = Profile.GetProfile(user.UserName);
DropDownList3.Items.Clear();
foreach (SettingsProperty p in
ProfileCommon.Properties)
{
DropDownList3.Items.Add(p.Name);
}
MultiView1.ActiveViewIndex = 4;
break;
}
</code></pre>
