在asp.net中二进制图片显示?该如何解决

在asp.net中二进制图片显示?
<asp:TemplateField HeaderText="缩略图">
  <EditItemTemplate>
  <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
  </EditItemTemplate>
  <ItemTemplate>
  <a href="../showImg.aspx?object=AD&objectID=<%# Eval("ID") %>" target="_blank">
  <img onload="ResizeImage(this,60,60)" alt="图片" src="../showImg.aspx?object=AD&objectID=<%# Eval("ID") %>" /></a>
  </ItemTemplate>
  </asp:TemplateField>

这是gridview里的一模板列,要显示缩略图/

showImag.aspx是要显示图片的页面.

这个怎么做啊?是要从数据库的二进制图片读取出来!谢谢!

C# code

读取图片using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Drawing;using System.Drawing.Imaging;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.IO;using System.Data.SqlClient;using MySql.Data.MySqlClient;public partial class Default2 : System.Web.UI.Page{    MySqlConnection conn = new MySqlConnection(System.Configuration.ConfigurationManager.AppSettings["conmy"]);    protected void Page_Load(object sender, EventArgs e)    {              if (!this.Page.IsPostBack)         {            this.show();          }    }    public void show()     {                    string ss = Request.QueryString["id"].ToString();            string s3 = "select * from imgpic  where id=" + ss;            MySqlCommand comm = new MySqlCommand(s3, conn);            conn.Open();            MySqlDataReader dr = comm.ExecuteReader(CommandBehavior.CloseConnection);            while(dr.Read())            {                Response.Clear();                Response.C;                Response.BinaryWrite((byte[])dr["myimg"]);//读取            }            Response.End();            conn.Close();    }}注意图片显示要在另一张页面中在你要显示的页面添加img 控件src="显示你图片的页面"; 122058662 最后编辑于 2008-04-22 09:59:24
[解决办法]
在showImg.aspx中写代码

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Data.SqlClient;
using System.Drawing;
using System.Text;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

上面是引用
   protected void Page_Load(object sender, EventArgs e)
   {
       // 在此处放置用户代码以初始化页面

       连接数据库读取数据-----------------
       SqlDataReader Dr = data.GetDataReader(sql);

       if (Dr != null)
       {
           while (Dr.Read())
           {
               if (Dr[0] != null)
               {
                   Response.ContentType = "image/jpeg";
                   Response.BinaryWrite((byte[])Dr["photo"]);
               }
               else
               {
                   Response.Write("暂无图片");
               }
           }

       }
       else
       {
           Response.Write("暂无图片");
       }
       Dr.Close();
   }
