Question

我想将Windows Media Player嵌入到ASP.NET页面中。我用这个代码，它工作正常做到这一点：

<OBJECT id='mediaPlayer1' width="180" height="50" 
classid='CLSID:22d6f312-b0f6-11d0-94ab-0080c74c7e95' 
codebase='http://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701' 
standby='Loading Microsoft Windows Media Player components...' type='application/x-oleobject'> 
<param name='fileName' value="http.."> 
<param name='animationatStart' value='true'> 
<param name='transparentatStart' value='true'> 
<param name='autoStart' value="false"> 
<param name='showControls' value="true"> 
<param name ="ShowAudioControls"value="true"> 
<param name="ShowStatusBar" value="true"> 
<param name='loop' value="false"> 
<EMBED type='application/x-mplayer2' 
pluginspage='http://microsoft.com/windows/mediaplayer/en/download/' 
id='mediaPlayer' name='mediaPlayer' displaysize='4' autosize='-1' 
bgcolor='darkblue' showcontrols="true" showtracker='-1' 
showdisplay='0' showstatusbar='-1' videoborder3d='-1' width="420" height="380" 
src="http..."  
autostart="true" designtimesp='5311' loop="false"> 
</EMBED> 
</OBJECT> 

我的问题是，我想改变的网址在我后面的代码，（如here但它是在VB，不C＃），因为我加载从数据库中导出数据。那么有没有办法，我可以在c＃部分添加此代码，或者更好 - 从c＃部分访问url？

对不起，如果这是一个愚蠢的问题，但我现在搜索了几个小时..和this.FindControl（mediaPlayer1）;不工作。

覆盖的Render方法。
编辑它以满足您的要求。

protected override void Render(HtmlTextWriter writer) 
    { 
     StringBuilder stringBuilder = new StringBuilder("<OBJECT " 
      +"ID='" +this.ClientID + "' " 
      + "name='" + this.ClientID + "' " 
      +"CLASSID='CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6'" 
      +"VIEWASTEXT" 
      ); 
     stringBuilder.Append("<PARAM name='autostart' value='false'>"); 
     stringBuilder.Append("<PARAM name='autoplay' value='false'>"); 

     stringBuilder.Append("<PARAM name='URL' value='/" + fileUrl + "/" + selectedFile + "'>"); 

     stringBuilder.Append("<PARAM name='rate' value='1'>"); 
     stringBuilder.Append("<PARAM name='balance' value='0'>"); 
     stringBuilder.Append("<PARAM name='enabled' value='true'>"); 
     stringBuilder.Append("<PARAM name='enabledContextMenu' value='true'>"); 
     stringBuilder.Append("<PARAM name='fullScreen' value='false'>"); 
     stringBuilder.Append("<PARAM name='playCount' value='1'>"); 
     stringBuilder.Append("<PARAM name='volume' value='100'>"); 
     stringBuilder.Append("</OBJECT>"); 

     divWindowsMediaPlayer.InnerHtml = stringBuilder.ToString(); 

     base.Render(writer); 
    }
