problem to move an image in c#

I’ve written an application to move an image on the form with PictureBox. But my code only move it horizontally…I used one Timer.

I need to move the image horizontally from initial point (e.g. X0,Y0) to reach an exact location (e.g. (Xc,Y0) ) then move it vertically up or down to reach (Xc,Ym) and then move back it horizontally to reach (Xf,Ym).

I have written that part that move image horizontally to reach (Xc,Y0) but I don’t know how to write the others…

Here is my code that move from (X0,Y0) to (Xc,Y0):

public partial class Form1 : Form
{
    void timer_Tick(object sender, EventArgs e)
    {
        int x = pictureBox1.Location.X;
        int y = pictureBox1.Location.Y;

        pictureBox1.Location = new Point(x + 2, y);

        if (x > 500)
            timer1.Stop();
    }

    public Form1()
    {
        InitializeComponent();

        pictureBox1.ImageLocation = "1.png";
        pictureBox1.Size = new Size(36, 35);

        timer1.Interval = 15;

        timer1.Start();
        timer1.Tick += new EventHandler(timer_Tick);

    }
}

Besides, I have did some attempts but didn’t get any result…

Here is my attempts (try to change method timer_Tick ) :

    void timer_Tick2(object sender, EventArgs e)
    {
        int x = pictureBox1.Location.X;
        int y = pictureBox1.Location.Y;

        if (x <= 500)
            pictureBox1.Location = new Point(x + 2, y);

        if (x > 500)
        {
            if (y <= 250)
            pictureBox1.Location = new Point(x, y + 1);

            if (y == 250)
            {
                pictureBox1.Location = new Point(x - 2, y);
                if (x < 50)
                    timer1.Stop();
            }

        }
    }

Please guys help me to complete this...

The key is to use time rather than x as your key:

int t = 0;

void timer_Tick1(object sender, EventArgs e)
{
    t++;

    int x = pictureBox1.Location.X;
    int y = pictureBox1.Location.Y;

    if (t <= 250)//go right 500 in 250 ticks
        pictureBox1.Location = new Point(x + 2, y);
    else if (t <= 500)//...then go down 250 in 250 ticks
        pictureBox1.Location = new Point(x, y + 1);
    else if (t <= 750)//...then go left 500 in 250 ticks
        pictureBox1.Location = new Point(x - 2, y);
    else
        timer1.Stop();
}

because when you attempt to decrement x on the way back to x0, you will fall back into your first if block.
