Default Using Connection Strings - App.config

Hi folks,

I am using Visual Studio 2005 (C#) with SQL Server 2000. In my app.config file i have got a couple of connection strings to different SQL databases.

What I am wanting to do is to be able to create a SQL connection to a specific database using a specific connection string in the app.config file.

I have looked through the help files and there is nothing which sticks out.

I have founda method to get the connection string:

Code:
private DbConnection GetDatabaseConnection ( string name )
{
  ConnectionStringSettings settings = 
    ConfigurationSettings.ConnectionStrings[name];

  DbProviderFactory factory = DbProviderFactories.GetFactory
     ( settings.ProviderName ) ;

  DbConnection conn = factory.CreateConnection ( ) ;
  conn.ConnectionString = settings.ConnectionString ;
  return conn ;
}
But how would I use this to create a SQl connection??

Any help would be great thanks!!

Hi,

Whenever you are executing the CreateConnection method, the connection object will be created for the Provider Type you are specifying in the config file. For example, if you specified the provider type as "System.Data.Sql", the connection will be created for SQL.

So you need to create the command object for the connection by the following Method:

DBCommand command;
command=connection.CreateCommand();

command.CommandText="Select * from <table>";

Then Create the DataSet or DataReader object to fetch the data from the command object and assign the data to which control you want to assign to.

Thanks and Regards,

Senthil Kumar M.
