.net连接oracle(无客户端)

　　使用DDTek.Oracle.dll可以在没有安装oracle客户端的情况下连接远程的oracle。

　　

string _conString = "Host=192.168.1.1;Port=1521;User ID=userid;Password=password;SID=sid";
List<Dictionary<string,object>> dics = new List<Dictionary<string,object>>();
OracleConnection conn = new OracleConnection( _conString );
conn.Open();
OracleCommand cmd = conn.CreateCommand();
cmd.CommandText = "select * from table";
OracleDataReader reader = cmd.ExecuteReader();
while( reader.Read() )
            {
                Dictionary<string,object> dic = new Dictionary<string,object>();
                int fieldCount = reader.FieldCount;
                ; i < fieldCount; i ++ )
                {
                    dic.Add( reader.GetName(i) , reader[i] );
                }
                dics.Add( dic );
            }
conn.Close();
