# Setter

A method or property part that changes a value, often checking it first.

## What is **Setter**?

A **setter** is a method (or property part) that changes a value in an object. A good setter checks the new value before accepting it.

```csharp
public int Temperature
{
    get => temperature;
    set
    {
        if (value < 5 || value > 30) throw new ArgumentOutOfRangeException(nameof(value));
        temperature = value;
    }
}
```
