title: I need to compare list with Datatable and filter values using Linq
body: <p>I need to compare a list with Datatable column and return the result as the values from the list which are not present in DataTable.</p>
  
  <p>List:
  <a href="https://i.stack.imgur.com/tQLGQ.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tQLGQ.jpg" alt="List to compare"></a></p>
  
  <p>DataTable:
  <a href="https://i.stack.imgur.com/QYCCw.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QYCCw.jpg" alt="Datable to compare"></a></p>
  
  <p>Here I need to compare the list with Datable User Id column and return the result from the list which is not present in DataTable.</p>
  
  <p>For Example, 
  IMS022 and IMS029 are present in List and not present in Datable.Hence I should get IMS022, IMS029 as filter result</p>
  
  <p>Thanks in advance</p>
