    我的代码是这样的：
    <HTML>
    <HEAD>
    <TITLE>音乐播放页面</TITLE>
    <meta content="Microsoft Visual Studio .NET 7.1" name="GENERATOR">
    <meta content="C#" name="CODE_LANGUAGE">
    <meta content="JavaScript" name="vs_defaultClientScript">
    <meta content="http://schemas.microsoft.com/intellisense/ie5" name="vs_targetSchema">
    </HEAD>
    <BODY ms_positioning="GridLayout" bottomMargin=10 topMargin=10>
    <FORM id="Form1" method="post" runat="server">   
        <asp:Label id="lbl_MediaPlayer" style="Z-INDEX: 101; LEFT: 74px; POSITION: absolute; TOP: 80px"
         runat="server" Width="104px"></asp:Label>
          请欣赏音乐：
    </FORM>
    </BODY>
    </HTML>
    后台代码：protected void Page_Load(object sender, EventArgs e)
        {
            string FileName = Server.MapPath("~/123.rmvb");
            if (!this.IsPostBack)
