title: Compare Two DataTables for Non-Matching Records C#
body: <p>I'm curious how I can compare two data tables in C#. I have two data tables, data table one contains FirstName and LastName, data table 2 has Field1, Field2, First_Name, and Last_Name. </p>
  
  <p>I want to find records that exist in data table 1 that do not exist in data table 2. Anyone ever done this before? Any help would be appreciated. Thank you!</p>
