Database Connectivity with oracle database using c# -

while trying connect oracle database getting following error

"a network-related or instance-specific error occurred while establishing connection sql server. server not found or not accessible. verify instance name correct , sql server configured allow remote connections. (provider: named pipes provider, error: 40 - not open connection sql server)"} problem may silly 1 first time database need help:

my code is:

static void main(string[] args)       {          using (sqlconnection conn = new sqlconnection())          {             conn.connectionstring = "data source=orcl_boa; database=boanewdoc;user id=boanewdoc;password=boanewdoc;trusted_connection=true";             conn.open();            //code          } 

you may need reference oracle.manageddataaccess.dll on odtwithodac121012.zip can download oracle site. not use system.data.oracleclient obsolete.

            var connection = new oracleconnection(yourconnectionstring);             try             {                 connection.open(); //amk: stuff db               }             catch (exception exception)             { //amk: other stuff in case of error              }                         { if(connection !=null && connection.state==connectionstate.open)                  connection.close();             }
