title: Do ADO.Net DataTables have indexes?
body: <p>I am using VSTS 2008 + C# + .Net 3.5 + SQL Server 2008 + ADO.Net. If I load a table from a database by using a DataTable of ADO.Net, and in the database table, I defined a couple of indexes on the table. My question is, whether on the ADO.Net DataTable, there is related index (the same as the indexes I created on physical database table) to improve certain  operation performance on DataTable?</p>
  
  <p>thanks in advance,
  George</p>
