This is my code

 using (Bitmap tempImage = new Bitmap(pictureBox1.Image))
            {
                pictureBox1.Image.Save(@"C:\Users\Mena\Desktop", System.Drawing.Imaging.ImageFormat.Bmp);
            }

What is the problem in the code ?

Answer 1

You might need a filename...

pictureBox1.Image.Save(@"C:\Users\Mena\Desktop\file.bmp",
    System.Drawing.Imaging.ImageFormat.Bmp);
