In this chapter, we reviewed the various types of errors that might occur in our software and looked at several strategies for handling them. These include ignoring the problem, aborting the application, returning errors, and throwing exceptions. We also saw some of the benefits and pitfalls of returning errors, and how exceptions can often provide a more robust and flexible means of alerting your clients to problems. We saw how we can handle exceptions in layers, sometimes catching, using, and then rethrowing an exception, sometimes wrapping an implementation exception in a public exception type, and sometimes allowing exceptions to bubble up to the next layer of handlers. We saw what happens when an unhandled exception pops out at the top of the stack, and how we can use finally blocks at each layer to ensure that application state remains consistent, and resources can be released, whether exceptions occur or not. We then took a quick review of some of the most common exceptions provided by the framework, and how we might use them. Finally, we looked at creating our own exception types and why we might (and might not) wish to do so. We ve come a long way in the past few chapters, covering all of the everyday C# programming concepts you ll need. In the next few chapters, we ll look at features of the .NET Framework in more detail, and how we can best use them in C#; starting with the collection classes.

Most programs have to deal with multiple pieces of information. Payroll systems need to calculate the salary of every employee in a company; a space battle game has to track the position of all the ships and missiles; a social networking website needs to be able to show all of the user s acquaintances. Dealing with large numbers of items is a task at which computers excel, so it s no surprise that C# has a range of features dedicated to working with collections of information. Sets of information crop up so often that we ve already seen some of what C# has to offer here. So we ll start with a more detailed look at the collection-based features we ve already seen, and in the next chapter we ll look at the powerful LINQ (Language Integrated Query) feature that C# offers for finding and processing information in potentially large sets of information.

The ability to work with collections is so important that the .NET Framework s type system has a feature just for this purpose: the array. This is a special kind of object that can hold multiple items, without needing to declare a field for each individual item. Example 7-1 creates an array of strings, with one entry for each event coming up in one of the authors calendars over the next few days. You may notice a theme here (although one misfit appears to be a refugee from an earlier chapter s theme, but that s just how the author s weekend panned out; real data is never tidy).

string[] eventNames = { "Swing Dancing at the South Bank", "Saturday Night Swing", "Formula 1 German Grand Prix", "Swing Dance Picnic", "Stompin' at the 100 Club" };

Look at the variable declaration on the first line. The square brackets after string indicate that eventNames is not just a single string; it s an array of string values. These square brackets tie in with the syntax for accessing individual elements in the array. Example 7-2 prints the first and fifth items in the array. (So this will print out the text Swing Dancing at the South Bank , followed by Stompin at the 100 Club .)

Other important things you should know about static constructors are the following: A class can have both static and instance constructors. As with static methods, a static constructor cannot access non-static members of its class, and therefore cannot use the this accessor. Static constructors cannot be called by your program. They are called automatically by the system Before any instance of the class is created Before any static member of the class is referenced

Console.WriteLine(eventNames[0]); Console.WriteLine(eventNames[4]);

The number inside the square brackets is called the index, and as you can see, C# starts counting array elements from zero. As you may recall from 2, the index says how far into the array we d like C# to look to access the very first element, we don t have to go any distance into the array at all, so its index is 0. Likewise, an index of 4 jumps past the first four items to arrive at the fifth. To modify an array element you just put the same syntax on the lefthand side of an assignment. For example, noticing that I got one of the event names slightly wrong, I can update it, like so:

eventNames[1] = "Saturday Night Swing Club";
