how can i fix this error?
<p>im a newbie in <code>asp.Net</code> and i got some trouble with code
i have a code like this:</p>

<pre><code>public class Log : AbstractLog
{
    private void Init()
    {
        base.IdentityColumn = "base_log_id"; 
    }
    public int LogId
    {
        get { return base.GetValueAsInt("base_log_id"); }
        private set { base.SetValue("base_log_id", value); }
    }
}
</code></pre>

<p>i just get and set value in a table named <code>base_log_id</code>, and if i cover <code>// AbtractLog</code> after building it got this error:</p>

<pre><code>'object' does not contain a definition for GetValueAsInt,
'object' does not contain a definition for SetValue,
'object' does not contain a definition for IdentityColumn.
</code></pre>

<p>actually i have no code in <code>AbtractLog</code> class
so what should i write in <code>AbstractLog</code> ?<br/>
I'm using visual studio 2005</p>
