将上传的图像显示到gridview

Question

我能够在gridview上看到jpeg文件，但我想要的是看图像本身。这是我的按钮代码：

protected void Button1_Click(object sender, EventArgs e)
    {
        if (FileUpload1.HasFile)
        {
            string bname = TextBox1.Text;
            string city = DropDownList1.SelectedValue.ToString();

            string filename = Path.GetFileName(FileUpload1.FileName);
            FileUpload1.SaveAs(Server.MapPath("~/Images/") + filename);


            Execute("INSERT INTO building VALUES('" + bname + "','Binay',1, '" + filename + "')");
            Label3.Text = "sucess";

            SqlDataAdapter sda = new SqlDataAdapter("Select * from building",ConnectionString);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            GridView1.DataSource = dt;
            DataBind();
        }
        else
        {
            Label3.Text = "upload image";
        }


     }

任何建议都会有很大帮助。谢谢！
