主要有两种方法,一种是直接写连接字符串,令一种是将连接字符串下载web.config文件中,下面分别作说明: 直接将写连接字符串: private static string connstr = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=Mhost) (PORT=mport
主要有两种方法,一种是直接写连接字符串,令一种是将连接字符串下载web.config文件中,下面分别作说明:
直接将写连接字符串:
private static string connstr = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=Mhost) (PORT=mport)))(CONNECT_DATA=(SERVICE_NAME=mywervicename)));Persist Security Info=True;User Id=myusername; Password=mypassword"; private OracleConnection DBCONN = new OracleConnection(connstr);
将连接字符串写在web.config文件中
private static string connstr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString; private OracleConnection DBCONN = new OracleConnection(connstr);
这种方式的话要在配置文件中加入下面的配置信息
然后就可以打开连接并查询数据了
如下面
public void GetData() { if (DBCONN.State == ConnectionState.Closed) { DBCONN.Open(); string quarystr = "select * from tablename"; OracleCommand comm = new OracleCommand(quarystr, DBCONN); OracleDataReader reader; reader = comm.ExecuteReader(); while (reader.Read()) { string str = "" + reader.GetString(1); } } }
