C# Coding Conventions (C# Programming Guide)

C# Coding Conventions (C# Programming Guide): Below are our C# coding standards, naming conventions, and best practices.
Use these in your own projects and/or adjust these to your own needs.

The C# Language Specification does not define a coding standard. However, the guidelines in this topic are used by Microsoft to develop samples and documentation.
Coding conventions serve the following purposes:
  • They create a consistent look to the code, so that readers can focus on content, not layout.
  • They enable readers to understand the code more quickly by making assumptions based on previous experience.
  • They facilitate copying, changing, and maintaining the code.
  • They demonstrate C# best practices.

Naming Conventions and Standards:

Pascal casing: 

the first character of all words is upper case and the other characters are lower case.

Camel casing: 

the first character of all words, except the first word, is upper case and other characters are lower case.

Use Pascal casing for class names:


public class HelloWorld
{
  ...
}

Use Pascal casing for method names:


public class HelloWorld
{
  void SayHello(string name)
  {
    ...
  }
}

Use Camel casing for variables and method parameters:


public class HelloWorld
{
 int totalCount = 0;
 void SayHello(string name)
 {
  string fullMessage = "Hello " + name;
  ...
 }
}

Do not use Hungarian notation to name variables. In earlier days, most programmers liked it: having the data type as a prefix for the variable name and using m_ as the prefix for member variables, e.g:

string m_sName;
int nAge;
