1、创建一个用户控件 SwfPlayer.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="SwfPlayer.ascx.cs" Inherits="SwfPlayer" %>

后台代码：

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

public partial class SwfPlayer : System.Web.UI.UserControl
{
    private string _File;
    private int _Width;
    private int _Height;

    //设置Flash宽度属性
    public int Width
    {
        set { _Width = value; }
    }

    //设置Flash高度属性
    public int Height
    {
        set { _Height = value; }
    }

    //Flash文件
    public string File
    {
        set { _File = value; }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
    }

    //重新Render方法
    protected override void Render(HtmlTextWriter writer)
    {
        //Flash对象
        StringBuilder sb = new StringBuilder();
        sb.AppendFormat("<object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' codebase='http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0'width='{0}' height='{1}'>", _Width, _Height);
        sb.AppendFormat("<param name='movie' value='{0}'>", _File);
        sb.AppendFormat("<param name='quality' value='high'>");
        sb.AppendFormat("<embed src='{0}' quality='high' pluginspage='http://www.macromedia.com/go/getflashplayer' type='application/x-shockwave-flash' width='{1}' height='{2}'></embed>", _File, _Width, _Height);
        sb.Append("</object>");
        writer.Write(sb.ToString());
    }

}
