title: LINQ Query on Datatable to check if record exists
body: <p>I want to perform a LINQ query on a datatable called Records and check if a record exists. If it exists, I want to find out the row which it is in. How might I go about doing this?</p>
  
  <p>I wanted to do a .where on my datatable after adding the system.linq namespace but the method didnt seem to exist. Please advise</p>
