Figure 2-6. Step 3 lets you choose data types for each column. The onscreen prompt tells us that the General format will convert numeric values to numbers, date values to dates, and so on. We will choose each column in turn, and choose the Text data type for our data. The Phone Number column contains numbers, but we want Excel to treat them as text. The column heading in the Data preview window shows us the data type selected for each column. Click Finish after applying the Text data type to all columns (see Figure 2-7). Click OK to let Excel place the data beginning in cell A1 (see Figure 2-8). Click cell A1, and then stop the Macro Recorder. Figure 2-9 shows the data after it has been imported from the CSV file. On the Developer ribbon, click the Visual Basic command or press Alt+F11 to open the Visual Basic window. Let s take a look at the code Excel generated for us. We ll examine the differences between importing Access data and text data in the Macro Recorder.

Our first lambda expression was a single statement that ultimately evaluated to a Boolean. As you know full well, though, many delegate targets must perform a number of code statements. For this reason, C# 3.0 allows you to define lambda expressions using a set of code statements. When your expression must process the parameters using multiple lines of code, you can denote a scope for these statements using the expected curly brackets. Consider the following example update to the FindAll() invocation: // This time the lambda expression is built with a statement // block. var justATest = list.FindAll(i => { Console.WriteLine("Called by FindAll()!"); Console.WriteLine("value of i is currently: {0}", i); bool isEven = ((i % 2) == 0); return isEven; } ); foreach (var evenNumber in justATest) { Console.WriteLine(evenNumber); } In this case, our parameter list (again, a single integer named i) is being processed by a set of code statements. Beyond the calls to Console.WriteLine(), our modulo statement has been broken into two code statements for increased readability. Here, then, is the final version of our first lambda expression, whose output can be seen in Figure 30-6: static void Main(string[] args) { Console.WriteLine("***** Fun with Lambda Expressions *****\n"); // Make a list of integers using C# 3.0 // collection initialization syntax. var list = new List<int>() {20, 1, 4, 8, 9, 44}; // This time the lambda expression is built with a statement // block. var justATest = list.FindAll(i => { Console.WriteLine("Called by FindAll()!"); Console.WriteLine("value of i is currently: {0}", i); bool isEven = ((i % 2) == 0); return isEven; } ); Console.WriteLine("\nHere are the even numbers from your list:"); foreach (var evenNumber in justATest) { Console.WriteLine(evenNumber); } Console.ReadLine(); }

Given that the whole reason for lambda expressions is to provide a clean, concise manner to define an anonymous method (and therefore, indirectly a manner to simplify working with delegates), let s retrofit the CarDelegate project we created in 8. Recall that this example defined a Car type that defined two custom delegates (AboutToBlow and Exploded), as well as a set of methods (OnAboutToBlow(), RemoveAboutToBlow(), OnExploded(), and RemoveExploded()), which allows the caller to pass in delegate objects as parameters to register with or detach from the event source. Figure 30-7 should jog your memory.

Figure 30-7. The Car type from the CarDelegate project in 8 Here is a simplified version of that project s Program class that makes use of traditional delegate syntax to respond to each callback: class Program { static void Main(string[] args) { Console.WriteLine("***** More Fun with Lambdas *****\n"); // Make a car as usual. Car c1 = new Car("SlugBug", 100, 10); // Traditional delegate syntax. c1.OnAboutToBlow(new Car.AboutToBlow(CarAboutToBlow)); c1.OnExploded(new Car.Exploded(CarExploded)); // Speed up (this will generate the events.) Console.WriteLine("\n***** Speeding up *****"); for (int i = 0; i < 6; i++) c1.SpeedUp(20);
