Get Directory App_Data in A Static Helper File
<p>What am I supposed to write as CategoryPath to get the file in the App_Data folder?</p>

<p>Thanks</p>

<pre><code>/// &lt;summary&gt;
/// Summary description for XMLHelper
/// &lt;/summary&gt;
public static class XMLHelper
{
    public static string CategoryPath = "App_Data/Categories.xml";
    public static void InsertCategory(string categoryName, string moderator)
    {
        XElement cat = XElement.Load(CategoryPath);
</code></pre>
