# Dynamic Dispatch

Choosing which version of a method to run based on the object's real type, at run time.

## What is **Dynamic Dispatch**?

**Dynamic dispatch** is how polymorphism works under the hood: when a method is called, the program decides *while running* which version to use, based on the object's real type.

```csharp
Animal pet = new Dog();
pet.Speak(); // runs Dog.Speak(), not Animal.Speak()
```
