首先是添加ORACLE和SQL Server的引用（reference）,ORACLE用的是它自带的类库
Imports
System.Data.SqlClient
Imports
Oracle.DataAccess.Client
在app.config里面设好connection string,具体如下：
<
appSettings
>
<
add key
=
“
SQLServerConnectionString
“
value
=
“
Data Source=MAPPA03C;Initial Catalog=LVSS;Integrated Security=True
“
/>
<
add key
=
“
OracleConnectionString
“
value
=
“
DATA SOURCE=lvnet;PASSWORD=lvss;PERSIST SECURITY INFO=False;USER ID=LVSS
“
/>
</
appSettings
>
然后便是在获得SQL Server和Oracle连接.
