Naming Conventions and Standards

Note: The terms Pascal Casing and Camel Casing are used throughout this document. Pascal Casing- First character of all words are Upper Case and other characters are lower case. Example: B ack C olor Camel Casing -First character of all words, except the first word are Upper Case and other characters are lower case. Example: b ack C olor

7.1. Use Pascal casing for Class names

public class С HelloWorld

{

...

}

7.2. Use Pascal casing for Method names

void SayHello (string name)

{

...

}

7.3. Use Camel casing for variables and method parameters

int totalCount = 0;

void SayHello(string name)

{

string fullMessage = "Hello " + name;

...

}

7.4. Use the prefix “I” with Camel Casing for interfaces (example: IEntity). Use the prefix “C” with Camel Casing for classes (example: CHelloClass)

Исключение из этого правила: класс Engine

7.5. Use Hungarian notation to name variables. All variables should use camel casing.

Table 7.1.

Type	Prefix
bool	is
byte	byt
sbyte	sbt
char	chr
short	sht
ushort	ush
int	int
uint	uit
long	lng
ulong	ulg
float	flo
double	dbl
decimal	dcm
object	obj
string	str
enum	en
Date	dat
Array	arr

Example: local variable - strName

class member variable - mvStrName / mvObject / private ColCountries mvCountries - Type by self defined collections not using

module variable - modStrName

object variable - objName

7.6. Use Meaningful, descriptive words to name variables. Do not use abbreviations.

Good:

string strAddress

int intSalary

Not Good:

string nam

string addr

int sal

7.7. Do not use single character variable names like i, n, s etc. Use names like index, temp

One exception in this case would be variables used for iterations in loops:

for (int i = 0; i < count; i++)

{

...

}

If the variable is used only as a counter for iteration and is not used anywhere else in the loop, many people still like to use a single char variable (i) instead of inventing a different suitable name.

Note: you can to use the rule - to designate objective variables at viewing collections in in cycle for each with the prefix х.(example xObject.)

7.8. Do not use underscores (_) for local variable names.

7.9. All member variables must be prefixed with mv (member variant) so that they can be identified from other local variables.

7.10. Do not use variable names that resemble (ключевых, зарезервированных) keywords.

7.11. Prefix boolean variables, properties and methods with “is” or similar prefixes.

private bool isFinished

private bool mvIsFinished // for member variant

7.12. Namespace names should follow the standard pattern

<company name>.<product name>.<top level module>.<bottom level module>

Example: LizenzaDevelopment.ADAICA.adADR

7.13. Use appropriate prefix for the UI elements so that you can identify them from the rest of the variables.

Use appropriate prefix for each of the ui element. A brief list is given below. Since.NET has given several

controls, you may have to arrive at a complete list of standard prefixes for each of the controls (including third

arty controls) you are using.

Table 7.2

Control	Prefix
Label	lbl
TextBox	txt
DataGrid	dtg
Button	btn
ImageButton	imb
Hyperlink	hlk
DropDownList	ddl
ListBox	lst
DataList	dtl
Repeater	rep
Checkbox	chk
CheckBoxList	cbl
RadioButton	rdo
RadioButtonList	rbl
Image	img
Panel	pnl
PlaceHolder	phd
Table	tbl
Validators	val
ListView	lvw
TreeView	tvw
Menu	mnu

7.14. File name should match with class name.

For example, for the class HelloWorld, the file name should be HelloWorld.cs

7.15. Use Pascal Case for file names.

7.16. To use the table 7.3 for last element codes (priority behind the set forth above rules).

Table 7.3.

			must be	example
Application			ADAICA == Advanced Documents, Assets & Information Control Application
DB-User			ASOADAC == Advanced Service Orientated Architecture (SOA) Data Access Components (DAC)
DB-Objects – it was prefix AS, better should AD, because AS is a reserved word, we take also the prefix AD_
