Connection String

Hello Everyone,

I have a C# application and I need to connect to an oracle database sitting on a different computer.
The computer name is test and the database name is UDA.
I have the following connection string which does not seem to work.

Code:

string connectionString = "Data Source=UDA@test;User Id=username;Password=password";

Can anyone tell me how to construct a connection string which connects to an Oracle database sitting on a different machine.

Thanks vey much in advance

Susan
