Area attributes is often hooked up on the compiler produced backing subject in automobile-carried out properties. As an example, contemplate a revision to the individual course that provides a unique integer Id home. You compose the Id house employing an car-applied residence, but your design and style will not call for persisting the Id assets.
The instance higher than enforces the rule that the primary identify should not be blank or white Room. If a developer writes
The preceding code makes two additions to the individual class. To start with, the FirstName assets declaration includes the needed modifier. Meaning any code that results in a brand new Man or woman should set this house.
syntax to define procedures that contain just one expression. In this article, that expression returns the full identify for the person object.
That assignment throws an ArgumentException. Because a property set accessor have to have a void return kind, you report errors from the set accessor by throwing an exception.

Properties behave like fields once they're accessed. Even so, contrary to fields, properties are carried out with accessors that define the statements executed every time a property is accessed or assigned.
syntax. The compiler generates the storage location for the sector that backs up the property. The compiler also implements your body of your get and set accessors.
You can even prohibit modifications to a property making sure that it could possibly only be established within a constructor. You may modify the individual class so as follows:
Automobile-implemented properties can declare different accessibilities to the get and established accessors. You normally declare a community get accessor and A non-public set accessor. You may find out more during the article on limiting accessor accessibility.
The NonSerializedAttribute can only be connected to fields, not properties. You can attach the NonSerializedAttribute on the backing subject to the Id assets by utilizing the sector: specifier about the attribute, as shown in the next instance:
Each the get and also the established accessors conduct the required conversion between hours and seconds. Additionally, the set accessor validates the info and throws an ArgumentOutOfRangeException if the volume of several hours is invalid.
The preceding case in point lets a caller to make a Person utilizing the default constructor, even though that code does not established the FirstName residence. Beginning in C# 11, you are able to have to have
The home definition proven higher than is actually a read through-write residence. Observe the search term benefit in the set accessor. The set accessor constantly has an individual parameter named worth. The get accessor need to properties return a value that may be convertible to the kind of the assets (string in this example).
