1. Visual C# is an object-oriented language used to write application programs
that run in Windows or on the Internet using a graphical user interface (GUI).
2. In the OOP object model, classes are used to create objects that have
properties, methods, and events.
3. The current release of C# is called Visual C# 2005 and is one part of Visual
Studio. C# is available individually in an Express Edition and a Standard
Edition, or in Visual Studio Professional Edition and Team System version.
4. The .NET Framework provides an environment for the objects from many
languages to interoperate. Each language compiles to Microsoft Intermediate
Language (MSIL) and runs in the Common Language Runtime (CLR).
5. To plan a project, first sketch the user interface and then list the objects
and properties needed. Then plan the necessary event-handling methods.
6. The three steps to creating a C# project are (1) define the user interface,
(2) set the properties, and (3) write the code.
7. A C# application is called a solution. Each solution may contain multiple projects,
and each project may contain multiple forms and additional files. The solution
file has an extension of .sln, a project file has an extension of .csproj,
and form files and additional C# files have an extension of .cs. In addition, the
Visual Studio environment and the C# compiler both create several more files.
8. The Visual Studio integrated development environment (IDE) consists of
several tools, including a form designer, an editor, a compiler, a debugger,
an object browser, and a Help facility.
9. C# has three modes: design time, run time, and debug time.
10. You can customize the Visual Studio IDE and reset all customizations back
to their default state.
11. You create the user interface for an application by adding controls from the
toolbox to a form. You can move, resize, and delete the controls.
12. The Name property of a control is used to refer to the control in code. The
Text property holds the words that the user sees on the screen.
13. C# code is written in methods. Methods begin and end with braces { }.
14. Project comments are used for documentation. Good programming practice
requires comments in every method and at the top of a file.
15. Most C# statements must be terminated by a semicolon. A statement may
appear on multiple lines; the semicolon determines the end of the statement.
Comments and some other statements do not end with semicolons.
16. Assignment statements assign a value to a property or a variable. Assignment
statements work from right to left, assigning the value on the right side of the
equal sign to the property or variable named on the left side of the equal sign.
17. The this.Close() method terminates program execution.
18. Each event to which you want to respond requires an event-handling
method, also called an event handler.
19. You can print out the C# code for documentation.
20. Three types of errors can occur in a C# project: syntax errors, which violate
the syntax rules of the C# language; run-time errors, which contain a statement
that cannot execute properly; and logic errors, which produce
erroneous results.
21. Finding and fixing program errors is called debugging.
22. You must have a clean compile before you run the program.
23. Following good naming conventions can help make a project easier to debug.
24. C# Help has very complete descriptions of all project elements and their uses.
You can use the How Do I, Contents, Index, Search, or context-sensitive Help.
