首先我把Media Player播放器做一个用户控件

代码如下

前台：

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MedayPlayer.ascx.cs" Inherits="Web.MedayPlayer" %><script language="javascript" type="text/javascript">    <asp:Literal ID="Literal1" runat="server"></asp:Literal>

var oeTags = '<object id="mediaPlayer" classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6"'         + 'width="' + width + '" height="' + height + '"'         + '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="autoStart" value="false"/>'         + '<param name="url"       value="' + videolink + '" />'         + '<param name="wmode"     value="transparent" />'         + '<param name="uiMode"    value="full" />'         + '<param name="loop"      value="false" />'         + '<embed id       ="EmbedmediaPlayer"'         + 'type        ="application/x-mplayer2"'         + 'src         ="' + videolink + '"'         + 'width       ="' + width + '"'         + 'height      ="' + height + '">'         + '</embed>'         + '</object>';    document.write(oeTags);</script>

后台代码：

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;

namespace Web{public partial class MedayPlayer : System.Web.UI.UserControl    {private int width;private int height;private string videolink;

public int Width        {set            {                width = value;            }        }

public int Height        {set            {                height = value;            }        }

public string Videolink        {set            {                videolink = value;            }        }

protected void Page_Load(object sender, EventArgs e)        {this.Literal1.Text = "var width=" + width + ";var height=" + height + ";var videolink='" + videolink + "';";        }    }}

调用前台代码：

<%@ Register Src="MedayPlayer.ascx" TagName="MedayPlayer" TagPrefix="uc5" %>//头部引用  <uc5:MedayPlayer ID="MedayPlayer1" runat="server" />//网页中嵌套

调用后台代码：

 /// <summary>///播放视频信息/// </summary>        public void Rpt_bfspBind()        {         

           DataSet ds = new sepco.BLL.hw_room().Getdataset("type=1 and id="+id);           title = ds.Tables[0].Rows[0]["title"].ToString();            uptime = ds.Tables[0].Rows[0]["addtime"].ToString();           this.MedayPlayer1.Width = 481;this.MedayPlayer1.Height = 359;this.MedayPlayer1.Videolink = "" + ds.Tables[0].Rows[0]["url"].ToString() + "";        }
