# Strategy Pattern

A pattern where interchangeable classes each hold one way of doing a task.

## What is **Strategy Pattern**?

The **Strategy pattern** puts each way of doing something in its own class and lets you swap them. A map app can switch between driving, walking and cycling route strategies.

```csharp
public interface IRouteStrategy { Route Plan(Place from, Place to); }

var planner = new RoutePlanner(new WalkingRoute());
planner.Strategy = new CyclingRoute(); // swap at run time
```
