Fields vs. Properties in C#: When Should You Use a Field Instead of a Property?

Fields and attributes in C#: When is the field instead of attributes?

In C#programming, understanding the difference between fields and attributes is very important. The field is a private variable that stores data, and the attribute provides controlled access to the data as an intermediate. So, when should we use fields instead of attributes?

Field: Private storage directly access

Fields are mainly used for internal data storage in the class. They are private and can be accessed directly by members of the class. However, this direct access may cause data access problems and code rigidity. Properties: package and accessibility

On the other hand, the attributes are encapsulated to the underlying field, and they are disclosed by a public contract called Getter and Setter. Getter retrieves data from the field, and setter updates the data. This packaging provides greater control of data operation methods to ensure data integrity and prevent unauthorized access.

Use scene

In order to determine the appropriate usage of fields and attributes, please consider the following guidance principles:

The field is used for internal state storage: When the data should be hidden outside the outside, or when the performance needs to be directly accessed for performance reasons.

Public attributes for external data disclosure:

When data access to be controlled (including verification or calculation).

• Example
• Consider the following categories:
The name of the field is stored, and the

attribute provides access to the field through Getter and Setter. This package allows additional logic (for example, verification) in the method of attributes.
