The examples earlier mentioned confirmed one among The best conditions of property definition: a study-generate home without validation. By producing the code you need within the get and established accessors, you may make a variety of eventualities.
The preceding instance needs callers to use the constructor that features the FirstName parameter. Callers won't be able to use object initializers to assign a worth towards the property. To help initializers, you may make the established accessor an init accessor, as proven in the next code:
Basic properties that need no customized accessor code might be applied possibly as expression system definitions or as vehicle-implemented properties.
syntax to outline techniques that incorporate an individual expression. Right here, that expression returns the full title for the individual item.
Now, the FirstName assets is usually accessed from any code, but it really can only be assigned from other code in the Person class.
To create a SaleItem, you will need to established each the Name and Value properties employing object initializers, as shown in the following code:
The next instance repeats the previous a person, besides that Name and Selling price are auto-applied properties. The example also eliminates the parameterized constructor, to make sure that SaleItem objects are now initialized using a connect with into the parameterless constructor and an object initializer.
Properties are top quality citizens in C#. The language defines syntax that allows developers to write down code that accurately expresses their structure intent.

This ultimate Edition evaluates the FullName assets only when required. If the previously calculated version is legitimate, It can be used. If A further condition adjust invalidates the previously calculated version, It will likely be recalculated.
A remaining state of affairs the place you must publish code within a home accessor properties will be to support the INotifyPropertyChanged interface utilised to inform information binding customers that a worth has modified. When the value of a assets variations, the article raises the INotifyPropertyChanged.
This method works for virtually any attribute you connect on the backing field on the car-implemented residence.
