Quick Tips for Following Csharp Coding Standards and Naming Conventions

Terminology

Camel Case (camelCase) : In this the first letter of word always in small letter and after that each word with Capital letter.

Pascal Case (PascalCase): In this First letter of every word is in capital letter.

Underscore Prefix (_underScore) : For underscore ( __ ), the word after _ use camelCase terminology.

Native DataType

Always use native datatype instead of .Net CTS type. For example use int instead of Int32 or Int64.

//Good
  private int _salary = 100;

//Bad
  private Int16 _salary = 100;
  private Int32 _salary=100;

Class

Always use PascalCase for class names. Try to use noun or noun phrase for class name.

public partial class About : Page
{
  //...
}

Methods

Always use PascalCase for method names.  Use maximum 7 parameter for a method.

 public string GetPosts(string postId)
 {
   //...
 }

NOTE: Don't use name as all character in CAPS.

Arguments and Local Variable

Always use camelCase with method’s arguments and local variables. Don't use Hungarian notation for variables.

public string GetPosts(string postId
{
   int numberOfPost = 0;            
}

NOTE: Don't use abbreviations for any words and don't use underscore ( _ ) in between any name.

Property

Use PascalCase for property. Never use Get and Set as prefix with property name.

private int _salary = 100;

public int Salary
{
   get
   {
      return _salary;
   }
   set
   {
       _salary = value;
   }
}

NOTE: Don't use name with start with numeric character.

Interface

Always use letter "I" as prefix with name of interface. After letter I, use PascalCase.

public interface IUser
{
     /// <summary>
     /// Check user is exists or not
     /// </summary>
     /// <returns>return bool value</returns>
     bool ValidateUser();
}

Private member variable

Always tried to use camelCase terminology prefix with underscore ( _ )

private int _salary = 100;

Public Member Varibale

Always use PascalCase for public member variable

public int Salary = 100;

Member variable

Declare member variable at the top on the class, If class has static member than it will come at the top most and after that other member variable

public class Account
{
    public static string BankName;
    public static decimal Reserves;
    public string Number {get; set;}
    public DateTime DateOpened {get; set;}
    public DateTime DateClosed {get; set;}
    public decimal Balance {get; set;}
    // Constructor
    public Account()
    {
      // ...
    }
}

Enum

Always use singular noun to define enum.

enum MailType
{
    Html,
    PlainText,
    Attachment
}

Namespace

Always use PascalCase for namespace.

namespace NextProgramming.Domain
