C# Syntax (Toggle Plain Text)
void ShowNumbers (params int[] numbers)
{
    foreach (int x in numbers)
    {
        Console.Write (x+" ");
    }
    Console.WriteLine();
}
 
...
 
int[] x = {1, 2, 3};
ShowNumbers (x);
ShowNumbers (4, 5);
void ShowNumbers (params int[] numbers)
{
    foreach (int x in numbers)
    {
        Console.Write (x+" ");
    }
    Console.WriteLine();
}

...

int[] x = {1, 2, 3};
ShowNumbers (x);
ShowNumbers (4, 5);

Re: Array as Argument

Note that the params keyword is not required unless you are going to add individual ints as multiple parameters to the method.
