C# How to get DataTable value
<p>I still new to C# and just have 3 months plus of learning process. I would like to seeking advice on how to extract data value from my DataTable I have create for validation checking.</p>

<pre><code>private void checker 
{
    string sqlSelect2 = "SELECT a.AccNo, a.CompanyName , a.CreditLimit, FROM Debtor a JOIN";
}
</code></pre>

<p>which i have named  TableCehecker, i do not need to put it to gridview, just for checking purposes.</p>

<p>In the private void process how can I extract dataTable TableCehecker and the value?</p>

<p>Thank you,
Brian</p>
