Difference between fields and properties C# Examples

The class contains fields and properties.

C# is a programming Language that provides OOP features. Classes contain state and behavior.

The class contains variables, properties, and fields

Both are variables defined in the class. The difference is in the use of scope and storage.

Let’s see what is variables and differences.

C# field variables

Fields are variables declared in a class, with private or protected scope. Since Classes encapsulate the data and restrict access outside a class. Fields provide restricted access.

Field variables used in a class or struct

class Employee{
    //field variable
    private String _name;

In the above example _name is a field that is not accessible outside a class.

Fields can be static or private variables

C# properties variables

Properties are variable fields that expose to external classes via the Set and Get methods. It supports encapsulation to hide the internal details.

It protects field variables to read and write using the property

class Employee{
    //field variable
    private String _name;

    // property variable
    public string Name {
        get { return name; }
        set { name = value; }

val employee = Employee()
employee.name = "Mark"    // setter method called
println(employee.name)    // getter method called

properties can have an accessor method such as set - to set the value, get - to get the value

public string Name { get; set; }

Difference between Properties and Fields

Properties exposed to externalFields are private to a class
properties never store the data inFields stores the data at class level
Interface has propertiesInterface has not fields variables
Properties variable contains virtualFields has no virtual
Properties allow fields to read and writeFields provides memory storage for a class
Properties might throw exceptionField never throw exception
Allows Side effects - exception, call methods etc.does not allow side effects
