Properties provide a way to enforce encapsulation by providing
accessors that give controlled access to private fields. However, in classes with multiple fields, it is not unusual that copy-and-paste is used to quickly create the needed properties, which can result
in the wrong field being accessed by a getter or setter.
class C
{
private int x;
private int y;
public int Y => x; // Noncompliant: The returned field should be 'y'
}
This rule raises an issue in any of these cases:
- A getter does not access the field with the corresponding name.
- A setter does not update the field with the corresponding name.
For simple properties, it is better to use auto-implemented
properties (C# 3.0 or later).
Field and property names are compared as case-insensitive. All underscore characters are ignored.
