Provider Factories When you use the Common Programming Model, you do not need to specify the provider-specific namespace, because the Provider Factories generate instances of the specified data provider. The following C# code snippet obtains an instance of the SQL Server data provider: DbProviderFactory factory = DbProviderFactories.GetFactory("DDTek.SQLServer"); DbConnection Conn = factory.createConnection(); Conn.ConnectionString = "Host=Accounting;Port=1433;User ID=test01;Password=test01; Database Name=test"); try { Conn.Open(); Console.WriteLine("Connection successful!"); } catch (Exception ex) { // Connection failed Console.WriteLine(ex.Message); } // Close the connection Conn.Close();
