Datalist中的图片导出Excel
文字部分正常导出,但图片部分就显示一个红叉
这是咋个回事儿?
我的导出代码:        HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=Excel.xls");
        HttpContext.Current.Response.Charset = "UTF-8";
        HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.Default;
        HttpContext.Current.Response.ContentType = "application/ms-excel";
        this.listPricure.Page.EnableViewState = false;
        System.IO.StringWriter tw = new System.IO.StringWriter();
        System.Web.UI.HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
        listPricure.RenderControl(hw);
        HttpContext.Current.Response.Write(tw.ToString());
        HttpContext.Current.Response.End();
前台显示图片代码<tr>
    <td>
       <a href='../CallRoute/ReadPhoto.aspx?id=<%# Eval("PHOTO_ID") %>' target="_blank">
       <img height="240px" width="320px" src='../CallRoute/readrealimage.aspx?id=<%# Eval("PHOTO_ID") %>' />
       </a>
     </td>
</tr>
