In this section we will focus on the accepted conventions for naming projects, files and variables, defined by Microsoft.
It is recommended to use a descriptive name for naming projects and files, which suggests the role of the respective file / project and at the same time the
PascalCase convention is also recommended. This is a convention for naming elements, in which each word, including the first one, starts with an uppercase character, for example
Example: this course starts with a First steps in coding lecture, therefore an exemplary name for the solution for this lecture can be
FirstStepsInCoding. The same convention applies for the files in a project. If we take for example the first problem in the First steps in coding lecture, it is called Hello World, therefore our file in the project will be called
In programming variables keep data, and for the code to be more understandable, the name of a variable should suggest its purpose. Here are some recommendations for naming variables:
- The name should be short and descriptive and to explain what the variable serves for.
- The name should only contain the letters a-z, A-Z, the numbers 0-9, and the symbol '_'.
- It is accepted in C# for the variables to always begin with a lowercase letter and to contain lowercase letters, and each next word in them should start with an uppercase letter (this naming is also known as
- You should be careful about uppercase and lowercase letters, because C# distinguishes them. For example,
Ageare different variables.
- The names of the variables cannot coincide with keywords in the C# language, for example
intis an invalid name for a variable.
|Although using the symbol
Here are some examples for well named variables:
Here are some examples for badly named variables, even though the names are correct according to the C# compiler:
_firstName(starts with '_')
AGE(it is written in uppercase)
Start_Index(starts with an uppercase letter and contains '_')
At a first look all these rules can seem meaningless and unnecessary, but with time passed and experience gaining you will see the need for norms for writing quality code in order to be able to work more easily and faster in a team. You will understand that the work with a code, which is written without complying with any rules for quality code, is extremely annoying.
