The Field vs property and constructors the most The calling functions from base all i struggle with is when should i use base(something) and when base.something

a property is a field with a getter/setter define

public class MyClass
{
    // this is a field.  It is private to your class and stores the actual data.
    private string _myField;

    // this is a property. When accessed it uses the underlying field,
    // but only exposes the contract, which will not be affected by the underlying field
    public string MyProperty
    {
        get
        {
            return _myField;
        }
        set
        {
            _myField = value;
        }
    }

    // This is an AutoProperty (C# 3.0 and higher) - which is a shorthand syntax
    // used to generate a private field for you
    public int AnotherProperty { get; set; } 
}

public class MyClass
{
    // this is a field.  It is private to your class and stores the actual data.
    private string _myField;

    // this is a property. When accessed it uses the underlying field,
    // but only exposes the contract, which will not be affected by the underlying field
    public string MyProperty
    {
        get
        {
            return _myField;
        }
        set
        {
            _myField = value;
        }
    }

    // This is an AutoProperty (C# 3.0 and higher) - which is a shorthand syntax
    // used to generate a private field for you
    public int AnotherProperty { get; set; } 
}

O okay now i get it so they have Like built in get and set methods

yeah and for example if you want to tranform your instance of a class in json you need to have some properties cause it doesn't detect field just use them all the time 😄

Okay How about the constructors and base keyword

x0rld 👻 🎃•3y ago

the contructor is a normal method but it return a new instance of your object and you have to call it like your class name

DownOP•3y ago

Okay and i can have many of them right

x0rld 👻 🎃•3y ago

yeah you can have multiple constructors

DownOP•3y ago

Okay okay Now this one

i've always used the base(x) I don't really have exeperience with inheritance in c#
