第一种是在apsx页面上放一个Lable控件

这种方式可以写Javascript等控制页面，和布局页面

如下：HTML页面代码：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
  <TITLE>多媒体播放页面</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: 8px; POSITION: absolute; TOP: 8px"
     runat="server" Width="104px"></asp:Label>
  </FORM>
</BODY>
</HTML>

.cs页面代码：

private void Page_Load(object sender, System.EventArgs e)
  {
   // 在此处放置用户代码以初始化页面
   if(!this.IsPostBack)
   {
       this.lbl_MediaPlayer.Text = this.PlayMedia(filename);
   }
  }

   public string PlayMedia(string MediaFile)
  {
   string strScript =
    "<TABLE id=\"Table2\" align=\"center\" border=\"0\" runat=\"server\" width = ‘620‘ height =‘450‘>"
    +"<TR>"
    +"<TD align=\"center\">"
    +"<OBJECT id=\"mdpTrailer\" classid=\"clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95\" name=\"mdpTrailer\" width=‘620‘ height = ‘450‘>"
    +"<PARAM NAME=\"AudioStream\" VALUE=\"-1\">"

    +"<PARAM NAME=\"AllowChangeDisplaySize\" VALUE=\"-1\">"
    +"<PARAM NAME=\"AutoRewind\" VALUE=\"0\">"
    +"<PARAM NAME=\"Balance\" VALUE=\"0\">"
    +"<PARAM NAME=\"BaseURL\" VALUE=\"\">"
    +"<PARAM NAME=\"BufferingTime\" VALUE=\"5\">"
    +"<PARAM NAME=\"CaptioningID\" VALUE=\"\">"
    +"<PARAM NAME=\"ClickToPlay\" VALUE=\"-1\">"
    +"<PARAM NAME=\"CursorType\" VALUE=\"0\">"
    +"<PARAM NAME=\"CurrentPosition\" VALUE=\"-1\">"
    +"<PARAM NAME=\"CurrentMarker\" VALUE=\"0\">"
    +"<PARAM NAME=\"DefaultFrame\" VALUE=\"\">"
    +"<PARAM NAME=\"DisplayBackColor\" VALUE=\"0\">"
    +"<PARAM NAME=\"DisplayForeColor\" VALUE=\"16777215\">"
    +"<PARAM NAME=\"DisplayMode\" VALUE=\"0\">"
    +"<PARAM NAME=\"DisplaySize\" VALUE=\"4\">"
    +"<PARAM NAME=\"Enabled\" VALUE=\"-1\">"
    +"<PARAM NAME=\"EnableContextMenu\" VALUE=\"-1\">"
    +"<PARAM NAME=\"EnablePositionControls\" VALUE=\"-1\">"
    +"<PARAM NAME=\"EnableFullScreenControls\" VALUE=\"0\">"
    +"<PARAM NAME=\"EnableTracker\" VALUE=\"-1\">"
    +"<PARAM NAME=\"Filename\" VALUE=\""+ MediaFile + "\">"
    +"<PARAM NAME=\"InvokeURLs\" VALUE=\"-1\">"
    +"<PARAM NAME=\"Language\" VALUE=\"-1\">"
    +"<PARAM NAME=\"Mute\" VALUE=\"0\">"
    +"<PARAM NAME=\"PlayCount\" VALUE=\"1\">"
    +"<PARAM NAME=\"PreviewMode\" VALUE=\"0\">"
    +"<PARAM NAME=\"Rate\" VALUE=\"1\">"
    +"<PARAM NAME=\"SAMILang\" VALUE=\"\">"
    +"<PARAM NAME=\"SAMIStyle\" VALUE=\"\">"
    +"<PARAM NAME=\"SAMIFileName\" VALUE=\"\">"
    +"<PARAM NAME=\"SelectionStart\" VALUE=\"-1\">"
    +"<PARAM NAME=\"SelectionEnd\" VALUE=\"-1\">"
    +"<PARAM NAME=\"SendOpenStateChangeEvents\" VALUE=\"-1\">"
    +"<PARAM NAME=\"SendWarningEvents\" VALUE=\"-1\">"
    +"<PARAM NAME=\"SendErrorEvents\" VALUE=\"-1\">"
    +"<PARAM NAME=\"SendKeyboardEvents\" VALUE=\"0\">"
    +"<PARAM NAME=\"SendMouseClickEvents\" VALUE=\"0\">"
    +"<PARAM NAME=\"SendMouseMoveEvents\" VALUE=\"0\">"
    +"<PARAM NAME=\"SendPlayStateChangeEvents\" VALUE=\"-1\">"
    +"<PARAM NAME=\"ShowCaptioning\" VALUE=\"0\">"
    +"<PARAM NAME=\"ShowControls\" VALUE=\"-1\">"
    +"<PARAM NAME=\"ShowAudioControls\" VALUE=\"-1\">"
    +"<PARAM NAME=\"ShowDisplay\" VALUE=\"0\">"
    +"<PARAM NAME=\"ShowGotoBar\" VALUE=\"0\">"
    +"<PARAM NAME=\"ShowPositionControls\" VALUE=\"-1\">"
    +"<PARAM NAME=\"ShowStatusBar\" VALUE=\"0\">"
    +"<PARAM NAME=\"ShowTracker\" VALUE=\"-1\">"
    +"<PARAM NAME=\"TransparentAtStart\" VALUE=\"0\">"
    +"<PARAM NAME=\"VideoBorderWidth\" VALUE=\"0\">"
    +"<PARAM NAME=\"VideoBorderColor\" VALUE=\"0\">"
    +"<PARAM NAME=\"VideoBorder3D\" VALUE=\"0\">"
    +"<PARAM NAME=\"Volume\" VALUE=\"-600\">"
    +"<PARAM NAME=\"WindowlessVideo\" VALUE=\"0\">"
    +"</OBJECT>"
    +"</TD>"
    +"</TR>"
    +"</TABLE>";

   return strScript;
  }

第二种方式是直接在aspx页面放置播放器代码

Html代码：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
  <TITLE>多媒体播放页面</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">
<object id="MediaPlayer1" classid="clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95" width="620" height="460" VIEWASTEXT>
     <param name="filename" value="<%=PlayUrl%>">
            <param name="AutoStart" value="1">
            <param name="Enabled" value="-1">
            <param name="ShowControls" value="-1">
            <param name="ShowGotoBar" value="0">

            <param name="AudioStream" value="-1">
            <param name="AutoSize" value="0">
            <param name="AnimationAtStart" value="-1">

            <param name="BaseURL" value="">
            <param name="BufferingTime" value="5">
            <param name="CaptioningID" value="">

            <param name="DefaultFrame" value="">
            <param name="DisplayBackColor" value="0">
            <param name="DisplayForeColor" value="16777215">
            <param name="DisplayMode" value="0">
            <param name="InvokeURLs" value="-1">
            <param name="Language" value="-1">

            <param name="PlayCount" value="1">
            <param name="PreviewMode" value="0">
            <param name="Rate" value="1">
            <param name="SAMILang" value="">

            <param name="SendOpenStateChangeEvents" value="-1">
            <param name="SendWarningEvents" value="-1">
            <param name="SendKeyboardEvents" value="0">
            <param name="SendMouseClickEvents" value="0">
            <param name="SendMouseMoveEvents" value="0">

      </FORM>

.CS页面

  private void Page_Load(object sender, System.EventArgs e)
  {
   // 在此处放置用户代码以初始化页面
   if(!this.IsPostBack)
   {
    int picID=System.Convert.ToInt32(Request.QueryString["pid"]);
    MyNature.SQLServerDAL.Picture pic = new MyNature.SQLServerDAL.Picture();
    string filename = pic.GetMulname(picID);
