int NewsId = Int16.Parse(Request.QueryString ["id"]);
DataTable dt = new DataTable();
dt = obj.GetNewsById(Operation，NewsId);
byte [] data =(byte [])obj.GetNewsById(Operation，NewsId).Rows [0] ["photo"];
if(数据！= null)
{
Byte [] bytImage =(data);
如果(bytImage！= null && bytImage.Length！= 0)
{
Response.ContentType ="image/jpeg";
Response.Expires = 0;
Response.Buffer = true;
Response.Clear();
Response.BinaryWrite(bytImage);
Response.End();
}
}

int NewsId = Int16.Parse(Request.QueryString["id"]);
DataTable dt = new DataTable();
dt = obj.GetNewsById(Operation, NewsId);
byte[] data =(byte[])obj.GetNewsById(Operation,NewsId).Rows[0]["photo"];
if (data != null)
{
Byte[] bytImage = (data);
