Field characteristics is usually hooked up towards the compiler created backing area in auto-applied properties. By way of example, take into account a revision to the individual course that provides a singular integer Id house. You publish the Id home employing an car-executed house, but your design would not call for persisting the Id property.
The preceding example needs callers to use the constructor that includes the FirstName parameter. Callers are unable to use object initializers to assign a value to the assets. To support initializers, you can also make the set accessor an init accessor, as demonstrated in the following code:
You'll be able to insert any restrictive accessibility modifier to both the set or get accessors. Any obtain modifier you put on the individual accessor should be extra confined in comparison to the obtain modifier within the house definition.
syntax to outline procedures that have an individual expression. Below, that expression returns the entire identify for the person item.
That assignment throws an ArgumentException. Due to the fact a home established accessor need to have a void return style, you report mistakes during the set accessor by throwing an exception.
It could throw a NullReferenceException without having this sign in that circumstance. To find out more, see situations. This example also employs the new nameof operator to convert with the property identify symbol to its textual content representation. Applying nameof can lessen faults where you've mistyped the identify from the property.
The subsequent illustration repeats the preceding one particular, except that Identify and Value are vehicle-executed properties. The example also eliminates the parameterized constructor, to ensure that SaleItem objects are actually initialized having a phone to your parameterless constructor and an item initializer.
Properties behave like fields after they're accessed. On the other hand, unlike fields, properties are carried out with accessors that outline the statements executed every time a house is accessed or assigned.
. This function permits details to be accessed quickly and still aids market the safety and adaptability of techniques.

A final circumstance exactly where you might want to generate code in a very house accessor is usually to support the INotifyPropertyChanged interface utilised to notify details binding consumers that a value has changed. When the value of the home adjustments, the item raises the INotifyPropertyChanged.
The house definition revealed previously mentioned is usually a read-write home. Notice the key word value during the established accessor. The properties established accessor generally has a single parameter named price. The get accessor will have to return a value which is convertible to the type of the house (string in this instance).
