A house isn't going to want to simply return the worth of a member area. You can produce properties that return a computed value. Let us develop the individual item to return the full title, computed by concatenating the main and last names:
The preceding case in point demands callers to use the constructor that features the FirstName parameter. Callers won't be able to use item initializers to assign a value to the house. To assist initializers, you can also make the established accessor an init accessor, as proven in the next code:
Straightforward properties that need no custom accessor code is often applied both as expression overall body definitions or as car-implemented properties.
Just one simple sample for implementing a assets requires using A non-public backing industry for environment and retrieving the house benefit. The get accessor returns the value with the personal industry, plus the established accessor may perhaps accomplish some data validation prior to assigning a value on the private industry.
That assignment throws an ArgumentException. Since a assets set accessor must have a void return style, you report mistakes inside the set accessor by throwing an exception.
If a property has equally a get plus a set (or possibly a get and an init) accessor, both of those should be car-carried out. You define an car-applied residence by utilizing the get and set keywords and phrases with no delivering any implementation.

Properties are first-class citizens in C#. The language defines syntax that permits builders to write code that accurately expresses their design intent.

You may extend this exact same syntax to something essential as part of your state of affairs. You'll be able to check the interactions between various properties, or validate versus any exterior problems. Any valid C# statements are legitimate in a home accessor.

Both the get and the set accessors carry out the mandatory conversion amongst hrs and seconds. Moreover, the established accessor validates the data and throws an ArgumentOutOfRangeException if the number of several hours is invalid.
