# Median

Canonical: https://www.wiki.jodisand.me/snippets/csharp/median/


Finds the median of a list of numbers.

- Use the `params` keyword to accept either an array or a variable number of arguments.
- Sort the array using `Array.sort()` and find the median.
- Which is either the middle element of the list, if the list length is odd or the average of the two middle elements, if the list length is even.

```csharp
public static partial class _30s 
{
  public static double Median(params double[] values)
  {
    Array.Sort(values);
    if (values.Length % 2 == 0)
      return (values[values.Length / 2 - 1] + values[values.Length / 2]) / 2;
    return (double)values[values.Length / 2];
  }
}
```

```csharp
double[] nums = { 5, 6, 7, 8 };

_30s.Median(4, 8, 1); // 4
_30s.Median(nums); // 6.5
```
