title: C# Datatable Local Copy
body: <p>I have an in memory DataTable in C#. I want to save a local copy of that on to my file system and retrive it . This C# datatable captures results from an excel formula and saves it. When the same excel file is opened again, I want to have the datatable loaded. This table is like a local cache that I want to reuse. </p>
  
  <p>Is there any other structure that I can use apart from a data table for such a caching behavior?</p>
  
  <p>How do I do that?</p>
