First, name
1. Use the PASCAL rules to name the method and type, and the class name adds a CLS prefix.
The PASCAL rule is: The first letter must be capitalized, and the first letter of the back and seminated consensus is uppercase, such as GeneralManager, SmallDictionary, Stringutil is a class name of this rule.
Public Class ClstextBox
{
Public void databind ()
{
}
}
2. Use the Camel rules to name the local variables and methods. And add the data type prefix. (Prefix but refer to appendix)
The Camel rule is: the first letter of all substrings outside the first substrong
String strusername;
Public adduser (String struserid, byte [] bypassword);
3. All member variables prefix M_
Public Class Database
{
Public string m_strconnectionstring;
}
4. The name of the interface adds prefix I.
Interface iCompare
{
INTCOMPARE ();
}
5. Customized properties end with Attribute
Public Class AuthorAttribute: Attribute
{
}
6. Customized exception ends with the EXCEPTION
Public Class APPEXCEPTION: Exception
{
}
7. Naming method. Generally named by a mobile phrase.
Showdialog ()
Createfile ()
GetPath ()
8. Corridation. To use Tab, not to use Space.
9. The name of the local variable must be meaningful. Do not use x, y, z, etc.
String Username
10. All member variables are declared at the top of the class and separate it from a wrap.
11. Name Namespace with meaningful name, such as: product name, company name.
12. It is recommended that local variables declare when it is closest to it.
13. When using a control value, try to name local variables.
14. Separate the Namespace from the referenced system and custom or third parties.
15. The file name is to react the content, it is best to be a class with the same name, a class in a file.
16. Big bracket "{" To a new line.
Public Class AuthorAttribute: Attribute
{
}
17 constant

User_password
Second, the coding habit.
1. Use the C # predefined class name instead of alias.
String username; not system.string username;
Int number; not system.int32;
2. Do not exceed 80 characters in one line.
3. Try not to manually change the code generated by the machine. If you must change, be sure to change it to the code style generated by the machine.
4. Key statements (including a key variable) must write comments.
5. Text constants and digital constants do not have hard coding, and should be replaced with constant classes or enumerations.
6. Don't use the GOTO family of statements.
7. Do not declare the member variables of public and protected, apply Property.
8. Do not declare the EVENT of the public, Apply Event Accessor.
Public Class Source
{
PRIVATE EVENTHANDLER M_NUMBERCHANGEVENT;
Public Event athandler NumberchangeEvent
{
Add
{
m_numberchangeeevent = value;
}
Remove
{
m_numberchangeeevent - = value;
}
}
}
9. Use rules for type conversion.
Animal Animal = New Dog ();
DOG DOG = Animal As Dog;
IF (Dog! = NULL)
{
}
10. When generating and build a long string, you must use StringBuilder without String.
11. Always use "{}" containing statements under IF / ELSE, even if there is only one statement.
12.switch statement must have DEFAULT to handle unexpected.
13. Try not to use this reference unless there is another constructor to call the class.
Public Class Person
