How to connect ASP.Net with Oracle Database?

How to connect asp.net with Oracle Database?
Where and How to? Thanks very much.

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=username;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 connectionstring";
oOracleConn.Open();

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

Thanks very much.
But if i wanna use ODP.Net to connect with ASP.Net?
Is it better then yours?
Then I am beginner.Thank you.

To answer your question I would say "yes", ODP.NET is better for working
with Oracle. The programming model is the same in most tasks and similar in
the rest and it is tuned to Oracle. There are a few instances where
OracleClient is better, due to having to work with both .NET and Java, but
it is generally neglegible. For the newest Oracle database (10g), I do not
believe you can use the OracleClient that ships with Visual Studio as the
Oracle internals have changed.

The code that Juan shared is very close to ODP.NET and you can download
samples of code for ODP.NET from the same site you download ODP.NET:

re:

Those *are* the connection strings for the
..NET Framework Data Provider for Oracle (ODP.NET).

You can download it at:
http://www.microsoft.com/downloads/...29-17dc-45ea-bfb3-076d1c052524&displaylang=en

And learn a bit more about it at:
http://www.c-sharpcorner.com/Code/2004/Feb/ODP.NET02.asp

You could also use OleDb :

This one's from Microsoft :
"Provider=msdaora;Data Source=MyOracleDB;User Id=UserName;Password=asdasd;"

The following are from Oracle :

Standard Security:
"Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;User
Id=Username;Password=asdasd;"

Trusted Connection:
"Provider=OraOLEDB.Oracle;Data Source=MyOracleDB;OSAuthent=1;"

Or, you could also use OraDirect : http://www.crlab.com/oranet/

OraDirect .NET supports Oracle 10g, 9i, 8i and 8.0,
including Personal and Lite editions.

Their provider works with .NET Framework 1.0, 1.1, and 2.0.
It will cost you $$$, though. ( $100 to $150 ).

Oh?Thanks very much~~I will try later..
