Tupel sind leichtgewichtige DTOs, die mehrere Werte unterschiedlicher Typen enthalten können. In C# gibt es zwei Arten von Tupeln.

<AccordionGroup>
  <Accordion title="`Tuple`">
    * Referenztyp
    * Unveränderlich
    * Werte sind Properties

    ```csharp theme={null}
    Tuple<int, string> tuple = new Tuple<int, string>(1, "one");
    ```
  </Accordion>

  <Accordion title="`ValueTuple`">
    * Wertetyp
    * Veränderlich
    * Werte sind Fields

    ```csharp theme={null}
    ValueTuple<int, string> valueTuple = new ValueTuple<int, string>(1, "one");
    ```
  </Accordion>
</AccordionGroup>

## Return-Types

```csharp theme={null}
(int Min, int Max) GetMinAndMax(int[] numbers)
{
    if (numbers.Length == 0)
    {
        throw new ArgumentException("Cannot find minimum and maxiumum of an empty array.")
    }
    
    int min = numbers[0];
    int max = numbers[0];
    
    foreach (int number in numbers) 
    {
        if (number < min)
            min = number;
            
        if (number > max)
            max = number;
    }
    
    return (min, max);
}
```
