C#中截取屏幕圖像的方法，有時有些程序需要監控用戶的屏幕或者是對屏幕進行截圖，這個C#函數就是實現這個功能。它可以截取全屏幕的圖像。具體源代碼如下：

        /// <summary>
        /// 截取全屏幕圖像
        /// </summary>
        /// <returns>屏幕位圖</returns>
        public Bitmap GetFullScreen()
        {
            Bitmap mimage = new Bitmap(System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width, System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height);
            Graphics gp = Graphics.FromImage(mimage);
            gp.CopyFromScreen(new Point(System.Windows.Forms.Screen.PrimaryScreen.Bounds.X, System.Windows.Forms.Screen.PrimaryScreen.Bounds.Y), new Point(0, 0), mimage.Size, CopyPixelOperation.SourceCopy);
            return mimage;
      }
