Store two columns of a datatable in one string using a separator
<p>I have a <code>DataTable</code> with the following structure</p>

<pre><code>ATM Fault
---------    
A01 34256
A02 56346
A03 98946
</code></pre>

<p>How can I store it in one string variable by using pipe delimiter as</p>

<pre><code>string temp="A01|34256,A02|56346,A03|98946";
</code></pre>

<p><strong>I was Converting My Linq To DataTable.But i it seems that i can do it in LINQ itself</strong></p>

<pre><code>var diff = dtOpenEvent.AsEnumerable().Except(dtOutputTemp.AsEnumerable(), DataRowComparer.Default);
DataTable di = diff.CopyToDataTable();//This is the Datatable which i want to Convert
</code></pre>

<p><strong>How Can i achieve same by modifying only <code>var diff</code> statement so that there is no need to convert it in DataTable</strong></p>
