C# Tutorial: Properties
Auto-properties, get/set, computed properties, and init-only properties.
Properties
Properties expose data from a class with controlled access. They look like fields to callers but can run logic on get or set.
Auto-properties are the shorthand: `public int Age { get; set; }` — the compiler generates the backing field.
What you'll learn in this C# properties tutorial
This interactive C# tutorial has 8 hands-on exercises. Estimated time: 15 minutes.
- Auto-properties — Auto-properties generate a backing field automatically.
- Read-only property — `{ get; }` without a setter makes the property read-only after construction.
- get with validation in set — Provide logic in the setter to validate before accepting values.
- init-only properties — `init` allows setting only during construction — immutable after.
- Required properties (C# 11) — `required` forces callers to initialise a property.
- Computed properties — Properties without a setter compute their value from other properties.
- Private setter — `{ get; private set; }` allows reading from outside but only setting from inside.
- Static properties — Static properties belong to the class, not instances.
