title: oracle connection String with C# using oledb
body: <p>Im developing an application in C# that connects to Oracle 10g.</p>
  
  <p>When I use ODP. Net and this </p>
  
  <p>Connection String <strong>"Data Source=Angelo-HP/XE;User ID=MAPFRE;Password=123456"</strong> 
  I can connect and perform any action with the database, </p>
  
  <p>but when I use OleDbConnection (System.Data.OleDb) with this </p>
  
  <p>connection String: <strong>"Provider=OraOLEDB.Oracle;OLEDB.NET=true;PLSQLRSet=true;User ID=mapfre;password=123456;Data Source=XE"</strong> 
  I got this error:</p>
  
  <p><strong>ORA-12154: TNS:could not resolve the connect identifier specified</strong></p>
  
  <p>When I try use Open() method from OleDbConnection.</p>
  
  <p>I think is not oracle configuration because I can connect from ODP and sqldeveloper client.</p>
  
  <p>Any idea?</p>
  
  <p>Thanks,</p>
