Read-Only and Write-Only Properties
You can leave one or the other of a property's accessors undefined by omitting its declaration.
A property with only a
get
accessor is called a
read-only
property. A read-only property
is a safe way of passing an item of data out from a class or class instance without allowing
too much access.
A property with only a
set
accessor is called a
write-only
property. A write-only property
is a safe way of passing an item of data from outside of the class to the class without
allowing too much access.
At least one of the two accessors must be defined; otherwise, the compiler will produce
an error message.
Figure 6-10 illustrates read-only and write-only properties.
