How to define and use properties in C#?

In C#, properties are members of a class used to encapsulate fields, providing a way to read and write data. Here are the basic steps for defining and using properties.

Define Attributes

Declare properties in a class: Define properties using the get and set keywords, specifying the data type and name of the property.

public class MyClass
{
    private int _myProperty;

    public int MyProperty
    {
        get { return _myProperty; }
        set { _myProperty = value; }
    }
}

Auto properties: If a property does not require any additional logic processing, you can use auto properties to simplify the definition.

public class MyClass
{
    public int MyProperty { get; set; }
}

utilize attributes

Set the attribute value: access the attribute by its name and assign a new value.

MyClass obj = new MyClass();
obj.MyProperty = 10;

Retrieve property value: Access the property by name and get its value.

int value = obj.MyProperty;

3. Access modifiers for properties allow control over access permissions using keywords like public or private, as well as using readonly to make properties read-only.

public class MyClass
{
    public int PublicProperty { get; set; }
    private int PrivateProperty { get; set; }
    public int ReadOnlyProperty { get; } = 100;
}

4. Property initializer: allows initializing the value of a property directly when declaring it.

public class MyClass
{
    public int InitializedProperty { get; set; } = 50;
}

Defining and using attributes helps to better manage a class’s data members, increasing the encapsulation and maintainability of the code.
