Now that we have these extension methods, look at how all objects (which of course means everything in the .NET base class libraries) have a new method named DisplayDefiningAssembly(), while System.Int32 types (and only integers) have methods named ReverseDigits() and Foo(): static void Main(string[] args) { Console.WriteLine("***** Fun with Extension Methods *****\n"); // The int has assumed a new identity! int myInt = 12345678; myInt.DisplayDefiningAssembly(); // So has the DataSet! System.Data.DataSet d = new System.Data.DataSet(); d.DisplayDefiningAssembly(); // And the SoundPlayer! System.Media.SoundPlayer sp = new System.Media.SoundPlayer(); sp.DisplayDefiningAssembly(); // Use new integer functionality. Console.WriteLine("Value of myInt: {0}", myInt); Console.WriteLine("Reversed digits of myInt: {0}", myInt.ReverseDigits());

1. In the BirthYear function, add the following code above the If...End If statement: MsgBox "Current Year: " & CStr(iCurrYear) MsgBox "Birth Year before If: " & CStr(iReturn) 2. Insert a blank line after the If...End If statement. 3. Add the following code: MsgBox "Birth Year after If: " & CStr(iReturn) Your code should now look like Listing 7-2. Listing 7-2. BirthYear Function with MsgBox Debugging Function BirthYear(Age As Integer, HadBDay As Boolean) Dim iReturn As Integer Dim iCurrYear As Integer iCurrYear = Year(Date) iReturn = iCurrYear = Age MsgBox "Current Year: " & CStr(iCurrYear) MsgBox "Birth Year before If: " & CStr(iReturn) If Not HadBDay Then iReturn = iReturn - 1 End If MsgBox "Birth Year after If: " & CStr(iReturn) BirthYear = iReturn End Function We re checking to see that the Year function is returning the correct value, and we re checking our return value before and after the If...End If statement to see if the code fell into it and possibly changed there. 4. Run the code in the Immediate window, clicking OK at each message box. Figures 7-7, 7-8, and 7-9 show us that our current year value looks good but the iReturn value has a problem. The problem must lie in our logic.

Now that we have a design, we need to figure out how to structure the information within our (X)HTML document The obvious elements we need to account for are the four boxes, the logotype, and the list of links in the middle We ve decided to make this a fixed-width layout, with the content elements centered in the browser After a little thought, we can see the four boxes are in two columns of two boxes each, with the link list as a third, center column We can float the two outer columns to the left and right, and center the link list in between, as long as the center column comes last in the source (which is perfectly fine in this case, since we d like the other content to display first for users viewing the site without styles or on an alternate browsing device).

Recall that the first parameter of an extension method is marked with the this keyword, followed by the type of item the method is applicable to. If we peek at what is happening behind the scenes (as verified by a tool such as ildasm.exe or Lutz Roeder s Reflector), we will find that the compiler simply calls the normal static method, passing in the variable calling the method as a parameter (e.g., it is the this). Consider the following C# code, which approximates the code substitution that took place: private static void Main(string[] args) { Console.WriteLine("***** Fun with Extension Methods *****\n"); int myInt = 12345678; MyExtensions.DisplayDefiningAssembly(myInt); DataSet d = new DataSet(); MyExtensions.DisplayDefiningAssembly(d); SoundPlayer sp = new SoundPlayer(); MyExtensions.DisplayDefiningAssembly(sp); Console.WriteLine("Value of myInt: {0}", myInt); Console.WriteLine("Reversed digits of myInt: {0}", MyExtensions.ReverseDigits(myInt)); TesterUtilClass.Foo(myInt); TesterUtilClass.Foo(myInt, "Ints that Foo Who would have thought it!"); }

Given that calling an extension method from an object (thereby making it seem that the method were in fact an instance-level method) is just some smoke-and-mirrors effect provided by the compiler, you are always free to call extension methods as normal static methods using the expected C# syntax (as just shown).
