webconfig中配置各种数据库的连接字符串(转)

一、在appSettings配置
<appSettings>

　　<!--SQL Server-->
　　<!--<add key="SQLString" value="Database=MyData;Data Source=NICKYAN-PC;User Id=sa;Password=123123;"/>
　　<add key="DataDAL" value="RedGlovePermission.SQLServerDAL" />-->

　　<!--My SQL-->
　　<add key="SqlString" value="host=192.168.0.222;userid=root;password=123456;database=hr_db"/>
　　<add key="DataDAL" value="RedGlovePermission.MySqlDAL" />

　　<!--Oracle-->
　　<add key="SqlString" value="Data Source=NICKYAN-PC;User Id=PB_DB_USER;Password=123123;Integrated Security=no"/>
　　<add key="DataDAL" value="RedGlovePermission.OracleDAL" />

　　<!--OleDB-->
　　<add key="SQLString" value="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=RedGlovePermission.Web\DB\MyData.mdb;Persist Security Info=False"/>
　　<add key="DataDAL" value="RedGlovePermission.OleDBDAL" />

</appSettings>

二、在connectionStrings配置

　　<!--SQL Server-->
<add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
<add name="ConnStr" connectionString="Database=DIS;Server=192.168.1.148;User ID=sa;Password=sa;" providerName="System.Data.SqlClient"/>

　　<!--My SQL-->

　　<add name="conStr" connectionString="server=localhost;uid=root;pwd=123;database=test"providerName="System.Data.SqlClient"/>

　　<!--Oracle-->
<add name="TYRCC_connstr" connectionString="Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=china-007cb92da) (PORT=1521))(CONNECT_DATA=(SERVICE_NAME=TYNHRK)));User ID=tytc;Password=123456;Unicode=True" providerName="System.Data.OracleClient" />
<add name="ConnectionString" connectionString="Data Source=TYNHRK;User ID=tytc;Password=123456.;Unicode=True" providerName="System.Data.OracleClient" />
<add name="ConnectionString2" connectionString="Expression: test_dataConnectionString" providerName="System.Data.SqlClient" />
