Code Notation Policy
The types of code notation used by a development group are the Camel and Pascal notation standards.
1. Instance private member field and method variables/fields and parameters: Use Camel notation (e.g., myVariable).
2. Web/Windows controls variables: Use Camel notation (e.g., btnSave).
3. All other public and protected identifiers for properties and methods: Use Pascal (e.g., MyClass).
4. Other code notation standards.
• Do not use Hungarian notation except for component naming on a form (e.g., “txtLastName” is okay for a textbox name on a form, but don’t use “iNumber” for a an integer variable or “oOjbect” for an object variable in a program.) See Table 3 below.
• Do not use a prefix for member variables (_, m_, s_, etc.). If you want to distinguish between local and member variables you should use “this.” in C# and “Me.” in VB.NET.
• Do use camelCasing for private member variables
• Do use camelCasing for method parameters
• Do use camelCasing for local variables
• Do use PascalCasing for function, property, event, and class names
• Do prefix interfaces names with “I”
Hungarian Prefix Connotation Example:
txt Text Box txtLastName
lbl Label lblMessage
opt Option or Radio Button optChoice1
chk Check Box chkCheck1
ddl Drop Down List ddlSelections
Table 1: Hungarian Notation for Form Control Names
Identifier Notation Example:
Class Pascal: Car
Constant Pascal: MaximumValue
Delegate Pascal: ChangeInformation
Enum Type Pascal: ColorChoice
Enum Value Pascal: OnlyBlack
Event (Delegate) Pascal; ChangeDirection
Event Handler Pascal OnChangeDirection
Exception Pascal OutOfOrderException
Static Member Variable Pascal ThisValue
Interface Pascal IEngine
Public Method Pascal StopEngine()
Namespace Pascal: Enterprise.BusinessRules
Property Pascal: RadiatorCap
Pascal notation is written as: “ThisIsPascal” (multiword) or “Pascal” (single word). The standard acknowledges the use of Pascal notation for class, constant, delegate, enum type, enum value, event, event handler, exception, static member variable, interface, method, namespace, and property.
