用文件流來顯示圖像

 首選創建文件流,然後以二進制方式讀出放在MemoryStream 中用以顯示.

FileStream fsp = new FileStream("D://Backup//我的文檔//3.jpg", FileMode.Open);
            BinaryReader  bbr = new BinaryReader(fsp);
            byte[] byteImage=bbr.ReadBytes((int)fsp.Length);
          
            MemoryStream ms = new MemoryStream(byteImage);

            this.pictureBox1.Image = Image.FromStream(ms);
