Web.config：OracleClient链接配置

第一种（较老做法）：appSettings

<add key="ConnectionString" value="Data Source=ORA11;User Id=ntsmp;Password=ntsmp;Integrated Security=no;"/>

第二种：connectionStrings

<connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=ORA11;Persist Security Info=True;User ID=ntsmp;Password=ntsmp;Unicode=True"
      providerName="System.Data.OracleClient" />
 </connectionStrings>
