image 有关问题

image 问题
将image 存入数据库及显示遇到了一些问题，我现在将他简化为显示image,将image 读入byte[],(其他的就是读写数据库)，然后将byte[]转化为stream,显示在另外一个pictureBox，（image读写，网上的例子都是这么说的）但现在出错。

C# code

if (openFileDialog1.ShowDialog()==DialogResult.OK  ){Stream ms=openFileDialog1.OpenFile ();pictureBox1.Image =Image.FromStream(ms) ; //正常byte[] imgbytes=new byte[ms.Length ] ;ms.Read(imgbytes,0,(Int32)ms.Length);  Stream  msview = new MemoryStream(imgbytes);  pictureBox2.Image =Image.FromStream(msview) ; //出错：“其他信息: 使用了无效参数。”

C# code

if(openFileDialog1.ShowDialog()==DialogResult.OK)            {                System.IO.FileStream Fs =new System.IO.FileStream(openFileDialog1.FileName,System.IO.FileMode.Open);                byte[] imgbytes =new byte[Fs.Length];                Fs.Read(imgbytes,0,imgbytes.Length);                Fs.Close();                System.IO.Stream  msview = new System.IO.MemoryStream(imgbytes);                  pictureBox1.Image =Image.FromStream(msview);            }
[解决办法]

数据库读取:
  foreach (DataRow ddr in ds.Tables[0].Rows)
               {
                   if (ddr["图片"] != DBNull.Value)
                   {
                       byte[] bytes = (byte[])ddr["图片"];
                       MemoryStream buf = new MemoryStream(bytes);
                       Image image = Image.FromStream(buf, true);
                       this.pictureBox1.Image = image;
                   }
                   else
                       this.pictureBox1.Image = null;
               }
