title: C# read open Excel file through OleDb
body: <p>I need to connect to an <strong>open</strong> Excel 2003 file using .NET 3.5</p>
  
  <p>It seems the OleDb connection which I am trying to use wants the file exclusively. But I need to have this file open in Excel in the same time.</p>
  
  <p>Is <strong>non-locking reading</strong> possible?</p>
  
  <p><strong>EDIT:</strong> I resolved this by copying file before opening it.</p>
