The above code has a bug while. If code updates the worth of possibly the FirstName or LastName property, the previously evaluated fullName discipline is invalid. You modify the set accessors from the FirstName and LastName property so that the fullName area is calculated once more:
The preceding example calls for callers to utilize the constructor that features the FirstName parameter. Callers are not able to use object initializers to assign a worth for the house. To support initializers, you may make the established accessor an init accessor, as demonstrated in the subsequent code:
You could increase any restrictive obtain modifier to both the set or get accessors. Any obtain modifier you position on the individual accessor must be extra minimal compared to accessibility modifier over the residence definition.
One essential sample for utilizing a residence includes applying a private backing field for placing and retrieving the home price. The get accessor returns the worth of the non-public discipline, plus the established accessor could perform some knowledge validation ahead of assigning a value into the private field.

To produce a SaleItem, it's essential to established the two the Identify and Price tag properties utilizing item initializers, as revealed in the subsequent code:
The subsequent case in point repeats the prior a person, except that Title and Cost are automobile-carried out properties. The instance also gets rid of the parameterized constructor, in order that SaleItem objects at the moment are initialized by using a phone for the parameterless constructor and an object initializer.
Properties behave like fields after they're accessed. Even so, in contrast to fields, properties are executed with accessors that determine the statements executed when a residence is accessed or assigned.
syntax. The compiler generates the storage site for the sphere that backs up the house. properties The compiler also implements your body in the get and set accessors.
You may as well restrict modifications to some residence to ensure it can only be set inside a constructor. It is possible to modify the individual class In order follows:

The instance earlier mentioned utilizes the string interpolation element to create the formatted string for the complete identify.
This remaining Variation evaluates the FullName residence only when required. When the Earlier calculated version is valid, It is really employed. If another point out transform invalidates the Beforehand calculated Edition, It's going to be recalculated.
A final circumstance wherever you must publish code in a very house accessor will be to assistance the INotifyPropertyChanged interface utilised to notify details binding clientele that a value has changed. When the value of a residence alterations, the item raises the INotifyPropertyChanged.
Callers will have to either utilize the constructor with SetsRequiredMembers or set the FirstName home making use of an item initializer, as revealed in the subsequent code:
