Code style is not correct or not, it is important to uniform, this is my proposed "Project code style requirements" for your reference.

1. C # code Style requirements 1.1 comments

Type, properties, events, methods, method parameters, and add comments as needed.

If the name of a type, property, event, method, method parameter is already self-explanatory, no comment is required; otherwise you must add a comment.

When you add a comment, the method is added as shown:

1.2 Types (classes, structs, delegates, interfaces), fields, properties, methods, naming of events

English is preferred, if the English does not have the appropriate word description, you can use pinyin, the use of Chinese is not in line with the requirements.

The only place where you can use Chinese is an enumeration of enumerated items, which are not actually part of the title of this section. Here just put together a description, as shown in:

1.3 Do not use abbreviations

Names of all types, methods, parameters, and variables must not be abbreviated, including the familiar abbreviations, such as MSG.

1.4 Code use semi-expansion

The first step is to open visual Studio and go to Tools, Options ..., as shown in:

In the second step, go to "text editor", "C #", "Formatting", "New Line", and uncheck the check boxes on the right, as shown in:

Third step, click "OK" to complete the setup.

1.5 use Tab as indentation and set indent size to 4

The first step is to open visual Studio and go to Tools, Options ..., as shown in:

In the second step, go to "text editor", "C #", "tab", as shown, set tab.

Third step, click "OK" to complete the setup.

1.6 A. cs source file with a maximum of two types defined

If two types of relationships are closely related, such as products, product types, the product class, and the ProductType enumeration can be defined in the same Product.cs file.

However, you cannot have two unrelated type definitions in a. cs file, such as defining the product class and the Reseller Class (reseller) in a BasicInfo.cs file.

1.7 type name and source file name must be the same

When a type is named product, its source file name can only be Product.cs.

1.8 All namespaces, type names using Pascal style (capitalize the first letter of the word)

As shown, the red flag is used in the Pascal style type:

Note that ProductType is a private type, regardless of whether the type is public or private, and its name is always in Pascal style.

1.9 Local variables, method parameter names using camel style (first letter lowercase, followed by the first letter of each word capitalized)

Red is marked with a camel-style variable or method parameter:

1.10 Private methods, protected methods, still named with Pascal style

The sample code is as follows:

1.11 If the IF statement contains only one row, you can do so without the braces, but you must be on the same line as the IF statement

The If judgment in example 1.9 is actually equivalent to the following statement:

1.12 Call the other members of the type, add this; Call the parent class member, add base

The sample code is as follows:

1.13 Type internal private and protected fields, named with Camel style, but prefixed with "_"

The code examples are as follows:

1.14 Public fields cannot appear

If a public field is required, the property is used for wrapping.

1.15 sort order of type members

The sort order of type members is from top to bottom:

Fields: Private fields, protected fields

Properties: Private property, protected property, public property

Events: Private events, protected events, public events

Constructors: Constructors with the highest number of parameters, constructors with a medium number of parameters, constructors with the fewest number of parameters

Method: The overloaded method is arranged in the same order as the constructor, from the maximum number of parameters down to the lowest parameter.

1.16 Naming of Delegates and events

The delegate is named EventHandler as a suffix, such as salesouteventhandler.

The event takes its corresponding delegate type, removes the EventHandler suffix, and adds an on prefix.

For example, for an event of the Salesouteventhandler delegate type, its event name is: Onsalesout.

The sample code is as follows:

1.17 Returns the method of type bool, the name of the property

If the type of the method returned is type bool, it is prefixed with is, can, or Try, for example:

1.18 Common collection type suffix naming

The corresponding suffix should be added to match the collection types listed in the following table.

Description Suffix Example
Array Array Int[] Productarray
List List List<product> ProductList
Datatable/hashtable Table HashTable producttable
Dictionary Dictionary Dictionay<string,string> productdictionary
The Dbset/dataset in EF Set Dbset<product> Productset
1.19 Common suffix naming

The corresponding suffix must be added to the local variables, method parameters, fields, and properties listed in the table below.
