從pictureBox導出圖像時出現錯誤

“ GDI +中發生一般錯誤”

**********例外文字**********

System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+.

這是我的代碼

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

代碼有什么問題？

您可能需要一個文件名...

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