Episode 33 question

 

I don't understand the (get, set) in the following line of code.  Is this a variable or a function?  Both?

 

public CurrencyCodes CurrencyCode { get; set; }

That's just a shortcut way of telling the compiler to automatically create get and set methods for the class that modify the property, which is a common thing to do with class properties.

[G+_Joe C. Hecht]

It is a declaration of a public "property" variable. Variables (properties) are often accessed via a Get method, and initialized via a set method. Like Lee Crocker  said, the compiler is adding those methods automatically. Setter methods allow you to do things like range check input, and perform other tasks For example, setter method for the BorderWidth of a Window control would set the value, and if the value changed,  would then update (redraw) the window using the new border width.  Getter methods usually require just a simple read, but can do more if required.

Thanks Joe Hecht and Lee Crocker .

Great stuff guys! There is an older post done on StackOverflow that explains what the compiler is doing by using examples: http://stackoverflow.com/a/341364

Very cool! I like the form

  public int Property { get; private set; }

where the property is only writable from a method in the same class. Makes it less likely for other parts of the program to mess up an object.
