i dont understand the application of a get set method. are there any practical examples you can give?

in C# we don't use get and set methods, we use properties that accomplish the same thing

int MyProperty { get; set; }

int MyProperty { get; set; }

int MyProperty { get; set; }

int MyProperty { get; set; }

basically, the reason to use them is that so the class has full control over its data

for example, maybe you don't want outside the class to change the value in which case you'd make the setter private

int MyProperty { get; private set; }

int MyProperty { get; private set; }

int MyProperty { get; private set; }

int MyProperty { get; private set; }

or you want to do some validation of the value

private int _myField;

public int MyProperty
{
  get => _myField;
  set
  {
    if (value > 100)
      throw new Exception("Number is too big");

    _myField = value;
  }
}

private int _myField;

public int MyProperty
{
  get => _myField;
  set
  {
    if (value > 100)
      throw new Exception("Number is too big");

    _myField = value;
  }
}

private int _myField;

public int MyProperty
{
  get => _myField;
  set
  {
    if (value > 100)
      throw new Exception("Number is too big");

    _myField = value;
  }
}

private int _myField;

public int MyProperty
{
  get => _myField;
  set
  {
    if (value > 100)
      throw new Exception("Number is too big");

    _myField = value;
  }
}

ah, so another class can reference

MyProperty

MyProperty

and that gives the value of

_myField

_myField

_myField

_myField

yes, but the class that contains MyProperty has control over what other classes can change the value to

J

Jimmacle•9/30/24, 6:38 PM

since it has to go through the setter

J

or if you wanted to change the value to be calculated by some other process, you can change that inside the class without other classes needing to know or be updated
