Hey guys,
I don't really understand the usage of the get/Set/return keywords.
get-Read Only
set-Write Only(eh)
return-Returns value to calling method
Those are the definitions I have but can I have a small explanation on when to use these and how to use the get/set thank you very much.
get and set are used with properties. return is used with methods that want to pass a value back to the calling code.
public int Age {get; set;} // Automatic property, don't have to worry
// about where it stores the value
private int weight;
public int Weight { // Normal property, we have to write the code
get { // and have a place to store it. This lets us
return weight; // do things like add validation to make sure
} // the value is in range, etc.
set {
if (value > 0) weight = value; // 'value' is the automatic name of the value
} // assigned.
}
public int MultiplyByTwo(int x) {
return x * 2; // the return tells it what value we want to pass back to the
} // calling method. The type must match the type given before
// the method name, in this case, an int
public void UseStuff() {
Weight = 43; // Assigning to the property automatically
// calls the 'set' method of the property.
int result = MultiplyByTwo(Weight); // Here we are calling the method defined
} // above and passing it the value of the
// Weight property (get is automatically
// called here). The value returned is assigned
// to the result variable.
Thank you guys for all your assistance!
