title: Datatable select with multiple conditions
body: <p>I have a datatable with 4 columns A, B, C and D such that a particular combination of values for column A, B and C is unique in the datatable.</p>
  
  <p><strong>Objective:</strong> To find the value of column D, for a given combination of values for column A, B and C.</p>
  
  <p>I guess looping over the set of data rows should do it. Is there a way to use Datatable.Select() to accomplish this? To be more specific - can I have multiple conditions in the select filter i.e. a logical AND operator connecting conditions for each of the columns A, B and C.</p>
