使用OracleConnection连接Oracle数据库的问题
我使用OracleConnection连接Oralce数据库,连接字符串是
Provider=MSDAOORA.1;Password   =   ***;User   ID   =   ***;   Data   Source   =   ***;Persist   Security   Info   =   true;

为什么创建连接的时候,他就说不支持关键字Provider,  
换成别的连接字符串也是一样报这个错误.
而我这些字符串在ASP或是Delphi环境下都能成功连接Oracle数据库的,   请高手帮帮我.谢谢

OracleConnection (.NET)


Standard:

"Data Source=MyOracleDB;Integrated Security=yes; "
This one works only with Oracle 8i release 3 or later
Specifying username and password:

"Data Source=MyOracleDB;User Id=myUsername;Password=passwd;Integrated Security=no; "
This one works only with Oracle 8i release 3 or later
Declare the OracleConnection:

C#:
using System.Data.OracleClient;
OracleConnection oOracleConn = new OracleConnection();
oOracleConn.ConnectionString = "my connection string ";
oOracleConn.Open();


VB.NET:
Imports System.Data.OracleClient
Dim oOracleConn As OracleConnection = New OracleConnection()
oOracleConn.ConnectionString = "my connection string "
oOracleConn.Open()
