Code Inspection: Auto-property can be made get-only (non-private accessibility)
This is a solution-wide code inspection. It only works when the solution-wide analysis is enabled.
Starting from C# 6.0, you can define get-only auto-properties, which (similarly to readonly fields) can be only initialized via a constructor or an initializer. Rider detects and helps you remove the redundant set accessor on auto-properties that are initialized from the constructor/initializer and have no write usages.
In the example below, an immutable class is intended, and once the value for the Name property is checked for nullability in the constructor, it can be safely used without further null checks. However, the private setter does not guarantee that the property will not be changed later in private members. Therefore, it is a good idea to make this property get-only to prevent any modifications.
public class Person
{
public string Name { get; set; } // Auto-property can be made get-only
public Person(string name)
{
Name = name ?? throw new ArgumentNullException(nameof(name));
}
public override string ToString()
{
return $"NAME: {Name.ToUpper()}";
}
}
