The C# Language Specification suggests that certain casing conventions be used in creating identifiers. The suggested guidelines for casing are described and summarized in Table 2-2. For most identifiers, the Pascal casing style should be used. In this style, each of the words combined to make an identifier is capitalized for example, FirstName and LastName. Table 2-2.

Keywords
Keywords are the character string tokens used to define the C# language. A complete list of the C# keywords is given in Table 2-3. Some important things to know about keywords are the following: Keywords cannot be used as variable names or any other form of identifier, unless prefaced with the @ character. All C# keywords consist entirely of lowercase letters. .NET type names, however, use Pascal casing. Table 2-3. The C# Keywords abstract as base bool break byte case catch char checked class const continue decimal default delegate do double else enum event explicit extern false finally fixed float for foreach goto if implicit in int interface internal is lock long namespace new null object operator out override params private protected public readonly ref return sbyte sealed short sizeof stackalloc static string struct switch this throw true try typeof uint ulong unchecked unsafe ushort using virtual void volatile while
CHAPTER 2 OVERVIEW OF C# PROGRAMMING
Main: The Starting Point of a Program
Every C# program must have one class with a method (function) called Main. In the SimpleProgram program shown previously, it was declared in a class called App. The starting point of execution of every C# program is at the first instruction in Main. The name Main must be capitalized. The simplest form of Main is the following: static void Main( ) { Statements }
Whitespace
Whitespace in a program refers to characters that do not have a visible output character. Whitespace in source code is ignored by the compiler, but is used by the programmer to make the code clearer and easier to read. Some of the whitespace characters include the following: Space Tab New line Carriage return For example, the following code fragments are treated exactly the same by the compiler in spite of their differences in appearance: // Nicely formatted Main() { Console.WriteLine("Hi, there!"); } // Just concatenated Main(){Console.WriteLine("Hi, there!");}
CHAPTER 2 OVERVIEW OF C# PROGRAMMING
Statements
The statements in C# are very similar to those of C and C++. This section will introduce the general form of statements; the specific statement forms will be covered in 9.
Simple Statements
A statement is a source code instruction describing a type or telling the program to perform an action. A simple statement is terminated by a semicolon. For example, the following code is a sequence of two simple statements. The first statement defines a variable named var1 and initializes its value to 5. The second statement prints the value of variable var1 to the screen. int var1 = 5; System.Console.WriteLine("The value of var1 is {0}", var1);
Blocks
A block is a sequence of zero or more statements enclosed by a matching set of curly braces; it acts as a single syntactic statement. You can create a block from the set of two statements in the preceding example by enclosing the statements in matching curly braces, as shown in the following code: { int var1 = 5; System.Console.WriteLine("The value of var1 is {0}", var1); } Some important things to know about blocks are the following: You can use a block whenever the syntax requires a statement but the action you need requires more than one simple statement. Certain program constructs require blocks. In these constructs, you cannot substitute a simple statement for the block. Although a simple statement is terminated by a semicolon, a block is not followed by a semicolon. (Actually, the compiler will allow it but it s not good style.) { Terminating semicolon Terminating semicolon int var2 = 5; System.Console.WriteLine("The value of var1 is {0}", var1); } No terminating semicolon
