Union on datatable
<p>How I will convert this SQL query in Linq, sorry but I am not that much expert in LINQ</p>

<pre><code>select ConnectionId
from LearnerConnections
where LearnerId = 1
union
select LearnerId
from LearnerConnections
where ConnectionId = 1
</code></pre>

<p>also can I write the DataTable methode to get the result (like DataTable.Select() method)?</p>

<p>thanks in advance</p>
