C# identifier naming rules and conventions

Naming rules

Valid identifiers must follow these rules:

Identifiers must start with a letter or underscore (_).
Identifiers may contain Unicode letter characters, decimal digit characters, Unicode connecting characters, Unicode combining characters, or Unicode formatting characters. For more information on Unicode categories, see the Unicode Category Database. You can declare identifiers that match C# keywords by using the @ prefix on the identifier. The @ is not part of the identifier name. For example, @if declares an identifier named if. These verbatim identifiers are primarily for interoperability with identifiers declared in other languages.

For a complete definition of valid identifiers, see the Identifiers topic in the C# Language Specification.

Naming conventions

In addition to the rules, there are many identifier naming conventions used throughout the .NET APIs. By convention, C# programs use PascalCase for type names, namespaces, and all public members. In addition, the following conventions are common:

Interface names start with a capital I.
Attribute types end with the word Attribute.
Enum types use a singular noun for non-flags, and a plural noun for flags.
Identifiers shouldn't contain two consecutive underscore (_) characters. Those names are reserved for compiler-generated identifiers.

For more information, see Naming conventions.

C# Language Specification

For more information, see the C# Language Specification. The language specification is the definitive source for C# syntax and usage.

9 - Naming Conventions

Naming conventions make programs more understandable by making them easier to read. They can also give information about the function of the identifier-for example, whether it's a constant, package, or class-which can be helpful in understanding the code.

Identifier Type	Rules for Naming	Examples
Packages	The prefix of a unique package name is always written in all-lowercase ASCII letters and should be one of the top-level domain names, currently com, edu, gov, mil, net, org, or one of the English two-letter codes identifying countries as specified in ISO Standard 3166, 1981. Subsequent components of the package name vary according to an organization's own internal naming conventions. Such conventions might specify that certain directory name components be division, department, project, machine, or login names.	com.sun.eng com.apple.quicktime.v2 edu.cmu.cs.bovik.cheese
Classes	Class names should be nouns, in mixed case with the first letter of each internal word capitalized. Try to keep your class names simple and descriptive. Use whole words-avoid acronyms and abbreviations (unless the abbreviation is much more widely used than the long form, such as URL or HTML).	class Raster; class ImageSprite;
Interfaces	Interface names should be capitalized like class names.	interface RasterDelegate; interface Storing;
Methods	Methods should be verbs, in mixed case with the first letter lowercase, with the first letter of each internal word capitalized.	run(); runFast(); getBackground();
Variables	Except for variables, all instance, class, and class constants are in mixed case with a lowercase first letter. Internal words start with capital letters. Variable names should not start with underscore _ or dollar sign $ characters, even though both are allowed. Variable names should be short yet meaningful. The choice of a variable name should be mnemonic- that is, designed to indicate to the casual observer the intent of its use. One-character variable names should be avoided except for temporary "throwaway" variables. Common names for temporary variables are `i`, `j`, `k`, `m`, and `n` for integers; `c`, `d`, and `e` for characters.	Copy `int i; char c; float myWidth;`
Constants	The names of variables declared class constants and of ANSI constants should be all uppercase with words separated by underscores ("_"). (ANSI constants should be avoided, for ease of debugging.)	static final int MIN_WIDTH = 4; static final int MAX_WIDTH = 999; static final int GET_THE_CPU = 1;

Which of the following is placed in a method heading to indicate that the method does not belong to an object?

The static modifier indicates that the method in question does not belong to an object and thus cannot be used to access any variables that belong to objects. Going forward, our methods will not include the static keyword if they're used to process information about objects created from a given class.

Which of the following modifiers is the least restrictive C#?

Let us understand each with an example..

Private. Private is the most restricted access level. ... .

Protected. The Protected access specifier restricts an object to be accessible only from derived instances of the class. ... .

Public. This is the least restricted access modifier. ... .

Internal. ... .

Protected Internal. ... .

Private Protected..

Which of the following modifiers is the least restrictive?

Java public access modifier: This is the least restrictive access modifier which means the widest range of accessibility, or visibility. When applied to a member, the member is accessible from any classes.

Which of the following modifiers is the most restrictive a private b static C public D internal e protected?

Methods, variables, and constructors that are declared private can only be accessed within the declared class itself. Private access modifier is the most restrictive access level. Class and interfaces cannot be private.
