8、NET is part of Microsofts overall .NET framework, which contains a vast set of programming classes designed to satisfy any conceivable programming need. In the following two sections, you learn how ASP.NET fits within the .NET framework, and you learn about the languages you can use in your ASP.NET

9、pages.The .NET Framework Class Libraryagine that you are Microsoft. Imagine that you have to support multiple programming languagessuch as Visual Basic, JScript, and C+. A great deal of the functionality of these programming languages overlaps. For example, for each language, you would have to inclu

10、de methods for accessing the file system, working with databases, and manipulating strings.Furthermore, these languages contain similar programming constructs. Every language, for example, can represent loops and conditionals. Even though the syntax of a conditional written in Visual Basic differs f

11、rom the syntax of a conditional written in C+, the programming function is the same.Finally, most programming languages have similar variable data types. In most languages, you have some means of representing strings and integers, for example. The maximum and minimum size of an integer might depend

12、on the language, but the basic data type is the same.Maintaining all this functionality for multiple languages requires a lot of work. Why keep reinventing the wheel? Wouldnt it be easier to create all this functionality once and use it for every language?The .NET Framework Class Library does exactl

13、y that. It consists of a vast set of classes designed to satisfy any conceivable programming need. For example, the .NET framework contains classes for handling database access, working with the file system, manipulating text, and generating graphics. In addition, it contains more specialized classe

14、s for performing tasks such as working with regular expressions and handling network protocols.The .NET framework, furthermore, contains classes that represent all the basic variable data types such as strings, integers, bytes, characters, and arrays.Most importantly, for purposes of this book, the

15、.NET Framework Class Library contains classes for building ASP.NET pages. You need to understand, however, that you can access any of the .NET framework classes when you are building your ASP.NET pages.Understanding NamespacesAs you might guess, the .NET framework is huge. It contains thousands of c

16、lasses (over 3,400). Fortunately, the classes are not simply jumbled together. The classes of the .NET framework are organized into a hierarchy of namespaces.ASP Classic NoteIn previous versions of Active Server Pages, you had access to only five standard classes (the Response, Request, Session, App

17、lication, and Server objects). ASP.NET, in contrast, provides you with access to over 3,400 classes!A namespace is a logical grouping of classes. For example, all the classes that relate to working with the file system are gathered together into the System.IO namespace.The namespaces are organized i

18、nto a hierarchy (a logical tree). At the root of the tree is the System namespace. This namespace contains all the classes for the base data types, such as strings and arrays. It also contains classes for working with random numbers and dates and times.You can uniquely identify any class in the .NET

19、 framework by using the full namespace of the class. For example, to uniquely refer to the class that represents a file system file (the File class), you would use the following:System.IO.FileSystem.IO refers to the namespace, and File refers to the particular class.NOTEYou can view all the namespac

20、es of the standard classes in the .NET Framework Class Library by viewing the Reference Documentation for the .NET Framework.Standard ASP.NET NamespacesThe classes contained in a select number of namespaces are available in your ASP.NET pages by default. (You must explicitly import other namespaces.

21、) These default namespaces contain classes that you use most often in your ASP.NET applications:System Contains all the base data types and other useful classes such as those related to generating random numbers and working with dates and times.System.Collections Contains classes for working with st

22、andard collection types such as hash tables, and array lists.System.Collections.Specialized Contains classes that represent specialized collections such as linked lists and string collections.System.Configuration Contains classes for working with configuration files (Web.config files).System.Text Co

23、ntains classes for encoding, decoding, and manipulating the contents of strings.System.Text.RegularExpressions Contains classes for performing regular expression match and replace operations.System.Web Contains the basic classes for working with the World Wide Web, including classes for representing

24、 browser requests and server responses.System.Web.Caching Contains classes used for caching the content of pages and classes for performing custom caching operations.System.Web.Security Contains classes for implementing authentication and authorization such as Forms and Passport authentication.Syste

25、m.Web.SessionState Contains classes for implementing session state.System.Web.UI Contains the basic classes used in building the user interface of ASP.NET pages.System.Web.UI.HTMLControls Contains the classes for the HTML controls.System.Web.UI.WebControls Contains the classes for the Web controls.N

26、ET Framework -Compatible LanguagesFor purposes of this book, you will write the application logic for your ASP.NET pages using Visual Basic as your programming language. It is the default language for ASP.NET pages. Although you stick to Visual Basic in this book, you also need to understand that yo

27、u can create ASP.NET pages by using any language that supports the .NET Common Language Runtime. Out of the box, this includes C#, JScript.NET, and the Managed Extensions to C+.NOTEDozens of other languages created by companies other than Microsoft have been developed to work with the .NET framework

28、. Some examples of these other languages include Python, SmallTalk, Eiffel, and COBOL. This means that you could, if you really wanted to, write ASP.NET pages using COBOL.Regardless of the language that you use to develop your ASP.NET pages, you need to understand that ASP.NET pages are compiled bef

29、ore they are executed. This means that ASP.NET pages can execute very quickly.The first time you request an ASP.NET page, the page is compiled into a .NET class, and the resulting class file is saved beneath a special directory on your server named Temporary ASP.NET Files. For each and every ASP.NET

30、 page, a corresponding class file appears in the Temporary ASP.NET Files directory. Whenever you request the same ASP.NET page in the future, the corresponding class file is executed.When an ASP.NET page is compiled, it is not compiled directly into machine code. Instead, it is compiled into an inte

31、rmediate-level language called Microsoft Intermediate Language (MSIL). All .NET-compatible languages are compiled into this intermediate language.An ASP.NET page isnt compiled into native machine code until it is actually requested by a browser. At that point, the class file contained in the Tempora

32、ry ASP.NET Files directory is compiled with the .NET framework Just in Time (JIT) compiler and executed.The magical aspect of this whole process is that it happens automatically in the background. All you have to do is create a text file with the source code for your ASP.NET page, and the .NET frame

33、work handles all the hard work of converting it into compiled code for you.ASP CLASSIC NOTEWhat about VBScript? Before ASP.NET, VBScript was the most popular language for developing Active Server Pages.ASP.NET does not support VBScript, and this is good news. Visual Basic is a superset of VBScript,

34、which means that Visual Basic has all the functionality of VBScript and more. So, you have a richer set of functions and statements with Visual Basic.Furthermore, unlike VBScript, Visual Basic is a compiled language. This means that if you use Visual Basic to rewrite the same code that you wrote wit

35、h VBScript, you can get better performance.If you have worked only with VBScript and not Visual Basic in the past, dont worry. Since VBScript is so closely related to Visual Basic, youll find it easy to make the transition between the two languages.NOTEMicrosoft includes an interesting tool named th

36、e IL Disassembler (ILDASM) with the .NET framework. You can use this tool to view the disassembled code for any of the ASP.NET classes in the Temporary ASP.NET Files directory. It lists all the methods and properties of the class and enables you to view the intermediate-level code.This tool also wor

37、ks with all the ASP.NET controls discussed in this chapter. For example, you can use the IL Disassembler to view the intermediate-level code for the TextBox control (located in a file named System.Web.dll).Introducing ASP.NET ControlsASP.NET controls provide the dynamic and interactive portions of t

38、he user interface for your Web application. The controls render the content that the users of your Web site actually see and interact with. For example, you can use controls to create HTML form elements, interactive calendars, and rotating banner advertisements.ASP.NET controls coexist peacefully wi

39、th HTML content. Typically, you create the static areas of your Web pages with normal HTML content and create the dynamic or interactive portions with ASP.NET controls.The best way to understand how ASP.NET controls work in an HTML page is to look at a simple Web Forms Page.Adding Application Logic

40、to an ASP.NET PageThe second building block of an ASP.NET page is the application logic, which is the actual programming code in the page. You add application logic to a page to handle both control and page events.If a user clicks a Button control within an HTML form, for example, the Button control

41、 raises an event (the Click event). Typically, you want to add code to the page that does something in response to this event. For example, when someone clicks the Button control, you might want to save the form data to a file or database.Controls are not the only things that can raise events. An AS

42、P.NET page itself raises several events every time it is requested. For example, whenever you request a page, the pages Load event is triggered. You can add application logic to the page that executes whenever the Load event occurs.2.Building Forms with Web Server ControlsBuilding Smart FormsYou use

43、 several of the basic Web controls to represent standard HTML form elements such as radio buttons, text boxes, and list boxes. You can use these controls in your ASP.NET pages to create the user interface for your Web application. The following sections provide detailed overviews and programming sam

44、ples for each of these Web controls.Controlling Page NavigationIn the following sections, you learn how to control how a user moves from one ASP.NET page to another. First, you learn how to submit an HTML form to another page and retrieve form information. Next, you learn how to use the Redirect() m

45、ethod to automatically transfer a user to a new page. Finally, you learn how to link pages together with the HyperLink control.Applying Formatting to ControlsIn the following sections, you learn how to make more attractive Web forms. First, you look at an overview of the formatting properties common

46、 to all Web controls; they are the formatting properties of the base control class. Next, you learn how to apply Cascading Style Sheet styles and classes to Web controls.3.Performing Form Validation with Validation ControlsUsing Client-side ValidationTraditionally, Web developers have faced a tough choice when adding form validation logic to their pages. You can add form validation routines to your server-side code, or you can add the validation routines to your client-side code.The advantage of writing validation logic in client-side code is that yo
