How to create a single Oracle Database connection method or function to be used on or by all classes and pages that want to connect to the database?

 How to create a single Oracle Database connection method or function  to be used on or by all classes and pages that want to connect to the database? How can I create one method or function in csharp to be used on all pages or classes when conenction to the database? Please give an example.

I have database connections which I am using on each and very page or classes, but I can I put in one page then I just start  calling it?

Database connection I am using:


  OracleConnection dbconnection;

    this.dbconnection = new System.Data.OracleClient.OracleConnection();
  this.dbconnection.ConnectionString = "user id=studentuser;data source=vdsoure;password=888hfg1";

I used to create an 'OracleConnection' whenever I need, instead of checking deeply for the way you expect to have. I think it's a one-step action!

Many Thanks & Best Regards,

   To add to what HuaMin said, you dont need to do that in .NET; maintains a connection pool automatically behind the scenes so is a cheap call that just gets a connection from the pool rather than opening a hard connection. Just create a new OracleConnection when you need it, and Dispose of it as soon as you're done with it so it can be returned to the pool.

Hope it helps,

How can I change my connection to a different is not connecting to the database I created.
My data is connected to the ASPNETDB.MDF database. Is this a must that I have it connected to this database or can I have it connected to a database that I created. You can connect to different database such as sql or other access files. All you have to do is to define which connection string to use within your web.config file. If you want to make sure that your database is prepared to be used, use features such as ASPNET_REGSQL.EXE at VS Command Prompt. Hope this helps. I'm in the in Georgia. Is it cold there..

Oracle 8i client connected to Oracle 9 database.
I have connected my Powerbuilder 9 application to a Oracle 9i database using Oracle 8i client. My Oracle home is set to 8. My Powerbuilder DB connection is using Oracle 8. Things seem to work. Why? In general, there will be compatibilty between client and server versions here; however, you'd have to check Oracle for their specific supported configurations. If you try to access anything new in Oracle 9 (like new datatypes, etc.), I expect you'll see problems that may be handled gracefully or not so gracefully.

Cannot connect to oracle database when using WAP
Does anyone know of any problems connecting to (oracle) databases when using WAP ???
