c# - Overwrite Existing Image

I have this code

    private void saveImage()
    {
        Bitmap bmp1 = new Bitmap(pictureBox.Image);
        bmp1.Save("c:\t.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
        // Dispose of the image files.
        bmp1.Dispose();
    }

i already have an image t.jpg at my drive "c:".
i wanted to replace it with a new image every time my program runs. but a GDI+ error shows up
how could i fix it?

You must remove your image if that is already exists.

private void saveImage()
    {
        Bitmap bmp1 = new Bitmap(pictureBox.Image);

       if(System.IO.File.Exists("c:\t.jpg"))
              System.IO.File.Delete("c:\t.jpg");

        bmp1.Save("c:\t.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
        // Dispose of the image files.
        bmp1.Dispose();
    }
