如何在asp.net中如何在线播放视频文件
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=\"AutoSize\" VALUE=\"-1\">"
+"<PARAM NAME=\"AutoStart\" VALUE=\"-1\">"

+"<PARAM NAME=\"Filename\" VALUE=\""+ MediaFile + "\">"
+"<PARAM NAME=\"InvokeURLs\" VALUE=\"-1\">"

+"<PARAM NAME=\"Mute\" VALUE=\"0\">"
+"<PARAM NAME=\"PlayCount\" VALUE=\"1\">"
+"<PARAM NAME=\"PreviewMode\" VALUE=\"0\">"

+"<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="JavaScript" name="vs_defaultClientScript">

</HEAD>
<BODY ms_positioning="GridLayout" bottomMargin=10 topMargin=10>

</object>
</FORM>
</BODY>
</HTML>
.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);
PlayUrl = filename；
}
}
