C# Feature � Computed properties

Overview

Computed properties return a value based on other state and avoid redundant storage.

Example

public class Rectangle
{
    public double Width { get; set; }
    public double Height { get; set; }
    public double Area => Width * Height; // Computed property
}

Notes

• Keep computations cheap; cache with a lazy property if expensive.
• Prefer methods if parameters are required for the computation.
