Function that swap two numbers

Hi i need a function that swap 2 numbers I have written code below but it seems to doesn't work. Where am I wrong?

(int, int) Swap(int first, int second)
{
    int temp = first;
    first = second;
    second = temp;
    return (first, second);
}

int a = 5;
int b = 10;

Console.WriteLine(a);
Console.WriteLine(b);
Swap(a, b);
Console.WriteLine(a);
Console.WriteLine(b);

(int, int) Swap(int first, int second)
{
    int temp = first;
    first = second;
    second = temp;
    return (first, second);
}

int a = 5;
int b = 10;

Console.WriteLine(a);
Console.WriteLine(b);
Swap(a, b);
Console.WriteLine(a);
Console.WriteLine(b);
