## What is **switch Statement** in C#?

**switch Statement** — A statement that compares one value against a list of cases and runs the one that matches, or `default` when none does. In C# a case can't fall through into the next: each one ends with `break` or `return`.

```csharp
string size = "M";
switch (size)
{
    case "S": Console.WriteLine("Small"); break;
    case "M": Console.WriteLine("Medium"); break;
    default: Console.WriteLine("Large"); break;
}
// Medium
```
