一。后台拼字符串动态加载写法

前台调用代码

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >

<head id="Head1" runat="server">

<title>视频播放</title>

</head>

<body>

<form id="form1" runat="server">

<div>

<table>

<tr>

<td><div id="video_content" runat="server" style=""></div> </td>

</tr>

</table>

</div>

</form>

</body>

</html>

后台调用代码

protected void Page_Load(object sender, EventArgs e)

{

this.video_content.InnerHtml = PlayMedia.Play("http://hot.tudou.com/flv/005/680/205/5680205.flv", 472,385);

}

视频播放类:

using System;

using System.Collections.Generic;

using System.Text;

namespace Common

{

public class PlayMedia

{

public PlayMedia()

{

//

// TOD 在此处添加构造函数逻辑

//

}

public static string Play(string url, int width, int height)

{

string strTmp = url.ToLower();

if (strTmp.EndsWith(".wmv") || strTmp.EndsWith(".mp3") || strTmp.EndsWith(".wma") || strTmp.EndsWith(".avi") || strTmp.EndsWith(".asf") || strTmp.EndsWith(".mpg"))

{

return wmv(url, width, height);

}

else if (strTmp.EndsWith(".mp3"))

{

}

}

二。前台拼字符串JS调用写法

FLV需要播放器，其它视频格式直接插入相应的代码即可。
