我要上传图片和显示???



我上传了图像然后将其转换为二进制然后保存在数据库中然后调用，现在我只想显示图像，请帮帮我??

这里的代码如下代码

  public   void  DisplayUploadedPhoto（）
 {
 
 Class1 cl =  new  Class1（）; 
  string  ID =会话[  IDUSER ]的ToString（）; 
 DataTable _T = cl._Get_PicInfoGV（  WHERE EmailID =' + ID +  '）; 
  Byte  [] bytes =（ Byte  []）_ T.Rows [ 0 ] [  PicData]; 
 
 MemoryStream mstream =  new  MemoryStream（bytes）; 
 System.Drawing.Image img1 = System.Drawing.Image.FromStream（mstream）; 
 
 
 
}

  string  ID =会话[  IDUSER ]的ToString（）; 
  byte  [] bytes =（ byte  []）cl._Get_PicInfoGV（  WHERE EmailID =' + ID +  '）。行[ 0 ] [  PicData]; 
  string  base64String = Convert.ToBase64String（bytes， 0 ，bytes.Length）;

I solved the problem.. thanks

Class1 cl = new Class1();
        string ID = Session["IDUSER"].ToString();
        byte[] bytes = (byte[])cl._Get_PicInfoGV(" WHERE EmailID = '" + ID + "'").Rows[0]["PicData"];
        string base64String = Convert.ToBase64String(bytes, 0, bytes.Length);
        Image1.ImageUrl = "data:image/png;base64," + base64String;
