loops - How can I draw a diagonal line with Console.SetCursorPosition c#?

Question

I need to do a function that received 3 entiers: horizontal and vertical position of the beginning of the line, as well as its length, and draws the diagonal line descending to the left. I don't understand how i can do the diagonal line. I have done a loop for do a horizontal line but I don't know what i need to change for draw a diagonal line.

For the horizontal line, I have done:

    static void LigneHorizontale(int posh, int pov, int longueur)
    {

            for (int i = 0; i < longueur; i++)
            {
                Console.SetCursorPosition(posh+i, pov);
                Console.WriteLine("-");
            }
    }

You need to increase the X:

    public static void LineHorizontale(int x, int y, int length)
    {
        for (var i = 0; i < length; i++)
        {
            Console.SetCursorPosition(x + i, y);
            Console.Write("-");
        }
    }

Diagonal:

public static void LineDiaglonal(int x, int y, int length)
{
    for (var i = 0; i < length; i++)
    {
        Console.SetCursorPosition(x + i, y + i);
        Console.Write('\');
    }
}
