Exception: Object reference not set to an instance of an object
<p>I have been using the code,</p>

<pre><code>  object amountObject = MySqlDAL.ExecuteQuerySingle(query);

        if (amountObject.Equals(System.DBNull.Value))
        {
            return amount;
        }
</code></pre>

<p>here in some point am getting an exception "Object reference not set to an instance of an object." from the sentence amountObject.Equals(System.DBNull.Value). Its working fine for some set of data.</p>

<p>What may be the reason? Can any one please help me out?</p>
