The following terms describe different ways to case identifiers.
The first letter in the identifier and the first letter of each subsequent concatenated word are capitalized. You can use Pascal case for identifiers of three or more characters. For example: BackColor
The first letter of an identifier is lowercase and the first letter of each subsequent concatenated word is capitalized. For example: backColor
All letters in the identifier are capitalized. For example: IO
When an identifier consists of multiple words, do not use separators, such as underscores ("_") or hyphens ("-"), between words. Instead, use casing to indicate the beginning of each word.
The following table summarizes the capitalization rules for identifiers and provides examples for the different types of identifiers:
Identifier | Case | Example |
---|---|---|
Local variable | Camel | carName |
Class | Pascal | AppDomain |
Enumeration type | Pascal | ErrorLevel |
Enumeration values | Pascal | FatalError |
Event | Pascal | ValueChanged |
Exception class | Pascal | WebException |
Read-only static field | Pascal | RedValue |
Interface | Pascal | IDisposable |
Method | Pascal | ToString |
Namespace | Pascal | System.Drawing |
