asp.net數據庫連接字符串集合

(一)常用連接:
1.使用SqlConnection對象:
public void SqlConnectionOpen()
{
   SqlConnection conn= new SqlConnection();
   conn.ConnectionString = "user id=sa;password=;initial catalog=northwind;datasource=localhost;connect Timeout=20";
   conn.Open();
}
2.使用OleDbConnection對象:
public void OleDBConnectionOpen()
{
   OleDBConnection conn = new OleDbconnection();
   conn.ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0;DataSource=C:/Customer.mdb";
   conn.Open();
}
(二)其它:
1.ODBC連接Access本地數據庫
  conGoodDay.Open("Driver={Microsoft Access Driver(*.mdb)};"+"Dbq=C:/a.mdb;"+
  "Uid=Admin;"+"Pwd=;");
2.ODBC連接Access系統數據庫
  conGoodDay.Open("Driver={Microsoft Access Driver(*.mdb)};"+"Dbq=C:/a.mdb;"+
  "SystemDB=Admin;"+"Pwd=;");
3.ODBC連接Access系統數據庫
  conGoodDay.Open("Driver={Microsoft Access Driver(*.mdb)};"+"Dbq=//server/share/a.mdb;");
4.ODBC連接Excel系統數據庫
  conGoodDay.Open("Driver={Microsoft Access Driver(*.xls)};"+"DriverId=790;"+
  "Dbq=C:/a.xls;"+"DefaultDir=c:/somepath;");
5.ODBC連接Oracle系統數據庫
  conGoodDay.Open("Driver={Microsoft ODBC for Oracle};"+"Server=OracleServer.world;"+
  "Uid=Admin;"+"Pwd=password;");
6.ODBC連接Sql Servr
  conGoodDay.Open("Driver={Sql Server};"+"Server=myServer;"+"Database=myDatabaseName;"
  "Uid=Admin;"+"Pwd=password;");
7.ODBC連接Visual FoxPro
  conGoodDay.Open("Driver={Microsoft Visual FoxPro Driver};"+
  "SourceType=DBC;"+"SourceDB=c:a.dbc;"+"Exclusive=No;");
