.net에서 Oracle 데이터베이스에 액세스하는 동안 솔루션 얻기 C#

System.Data.OracleClient를 사용하여 Oracle 데이터베이스에 액세스하는 C# 프로그램이 있습니다..net에서 Oracle 데이터베이스에 액세스하는 동안 솔루션 얻기 C#

이 코드는 OracleCommand, Dataset 객체를 사용합니다.

con = new OracleConnection(conStr); 
con.Open(); 
OracleDataAdapter adp = new OracleDataAdapter("select * from sample", con); 
DataSet ds = new DataSet(); 
adp.Fill(ds); 
DataTable dt = ds.Tables[0]; 
con.Close();

및

public static String conStr = "SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=******)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=******)));uid=#####;pwd=#######;"; 
private OracleConnection con; 
private String query; 
private OracleCommand cmd; 
private OracleDataReader rd;
