ASPX页面

ASPX page

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">

</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<embed type="application/x-mplayer2"

 pluginspage="http://www.microsoft.com/Winows/MediaPlayer/" name="mediaplayer1" ShowStatusBar="true"

EnableContextMenu="false" autostart="true" loop="true" src='<%Session[url1].ToString();> %>' style="width: 471px; height: 273px" />
</asp:Content> //It does'nt work


If i put src=direct path of file then it is palyed correctly.But url that comes from database does not played by palyer.
cs page
<pre lang="CS">
public partial class meiaplayer : System.Web.UI.Page
{
    public string link = "";
    protected void Page_Load(object sender, EventArgs e)
    {
      link = Session["url1"].ToString();

    }
}

推荐答案

如果HyperLink位于DataList中，则必须在DataList1_ItemCommand方法中设置Hyperlink的目标代替Response.Redirect()

If the HyperLink is in your DataList, then you must set the Hyperlink''s target in your DataList1_ItemCommand method instead of a Response.Redirect()
