Learning C# 3.0

Source Code

There you go—one complete, functional Windows application. Go ahead and test it out, but be careful what files you delete, because you won’t get them back. You may also run into permission issues, if you’re trying to access sensitive files or directories. Example 18-1 provides the full commented source code for this example.

ora: ASP.NET

One of the goals of Microsoft’s .NET initiative is to make it just as easy to create web applications as it is to create Windows applications. ASP.NET fulfills that goal for the Web. With ASP.NET, you can create applications using controls that are very similar to the ones you saw in this chapter, in a visual design environment that’s nearly identical to the form designer you used here. The difference between creating a Windows application and a web page is that in ASP.NET, you can either place the controls visually, or view the HTML source for the page and add controls as though you were writing HTML. You store the code for the web page in a separate file, just as you did in this chapter, but in ASP.NET, that code can be written in either C# or Visual Basic; it makes no difference to the web page.

If you’re using the full version of Visual Studio 2008, you can already create ASP.NET web pages; you just need to select ASP.NET Web Page in the New Project dialog box. However, we’ve written this book for the most part using C# Express, which doesn’t support ASP.NET, so we won’t go any further into the topic here.
