C#连接oracle（急）
用C#连接oracle连接字符串如下（报错，请高手写个完整的连接字符串)
"Provider=sqloledb;Data Source=local;Initial Catalog=db;uid=bizapp;pwd=sa";

[解决办法]

C# code

<?xml version="1.0" encoding="utf-8" ?><configuration>    <configSections>    </configSections>    <connectionStrings>                   <add name="ConnectionString"            connectionString="Data Source=orcl;Persist Security Info=True;User ID=hxjr;Password=123;Unicode=True"            providerName="System.Data.OracleClient" />    </connectionStrings></configuration>
