Naming Conventions
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. Recommended Identifier Naming Styles

Style Name Description Recommended Use Examples

CardDeck ,
DealersHand

Pascal casing Each word in the identifier

is capitalized.

Use for most identifiers.

totalCycleCount ,
randomSeedParam

Camel casing Each word in the identifier,

except the first , is capitalized.

Use for parameters and
local variables.

IO , DMA , XML Uppercase The identifier is composed

of all uppercase letters.

Use only for abbreviations.

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 pref-

aced with the @ character.

￿ All C# keywords consist entirely of lowercase letters. .NET type names, however, use

Pascal casing.
