ActiveCurrencyTrader cls = new ActiveCurrencyTrader(); double converted = cls.ConvertTo( 100.0); Imagine the situation where the values to convert to and from are text. To keep things general, you would write the following code. public double ConvertToTextField(ActiveCurrencyTrader cls) { return cls.ConvertTo(int.Parse(text1.Text)); } The implementation of ConvertToTextField() makes one major mistake in that it assumes that you will always be converting a currency using the ActiveCurrencyTrader implementation. If you wanted to use the class HotelCurrencyTrader, you would need to implement another method with a parameter of type HotelCurrencyTrader. This problem is the classical polymorphism problem and is solved by using abstract methods. Consider the following rewritten ConvertToTextField() method. public double ConvertToTextField(CurrencyTrader cls) { return cls.ConvertTo(int.Parse(text1.Text)); } This implementation of ConvertToTextField() uses the CurrencyTrader base class, and since ConvertTo() and ConvertFrom() are declared, they can be referenced. How you call ConvertToTextField() and how you instantiate HotelCurrencyTrader or ActiveCurrencyTrader will not be covered in this chapter, because polymorphism is the subject of the next chapter. Just keep what you ve learned about the abstract keyword in mind as you read that chapter, which covers concepts such as interfaces, because you can do the same types of things with it.

// Obtain the database connection string string connectionString = BalloonShopConfiguration.DbConnectionString; // Create a new data provider factory DbProviderFactory factory = DbProviderFactories. GetFactory(dataProviderName); // Obtain a database-specific connection object DbConnection conn = factory.CreateConnection(); // Set the connection string conn.ConnectionString = connectionString; // Create a database-specific command object DbCommand comm = conn.CreateCommand(); // Set the command type to stored procedure comm.CommandType = CommandType.StoredProcedure; // Return the initialized command object return comm; } } 11. In Solution Explorer, right-click the App_Code folder and choose Add New Item. Using the window that appears, create a new class named CatalogAccess (which would reside in a file named CatalogAccess.cs). Add the new code to the file: using System; using System.Data; using System.Data.Common; /// <summary> /// Product catalog business tier component /// </summary> public static class CatalogAccess { static CatalogAccess() { // // TODO: Add constructor logic here // } // Retrieve the list of departments public static DataTable GetDepartments() { // get a configured DbCommand object DbCommand comm = GenericDataAccess.CreateCommand(); // set the stored procedure name comm.CommandText = "GetDepartments"; // execute the stored procedure and return the results return GenericDataAccess.ExecuteSelectCommand(comm); } }

In this chapter, you learned some of the basics of object-oriented programming. The following are the key points to remember: Your code will be composed of structural or base class functionality, and architectural business-related functionality. Base class functionality is focused on a particular problem. The problem might be solved in a general manner, but only the particular problem is solved. Base class functionality requires specific knowledge of the field. Think of it as implementing a calculator where your main concern is ensuring that the calculations are correct. Architectural business-related functionality is higher-level functionality where general business knowledge is needed. The idea is to take the base classes, or base class related classes, and use them to solve a business problem. Think of it as using a calculator and your main concern is getting the results of the calculations. Properties should be used instead of exposing data members publicly.
