1.下载print2flash3 并且安装print2flash3

2.转换工具类

（1）需要导入using Print2Flash3; 这个程序集

using System;
using System.Data;
using System.Configuration;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using Print2Flash3;
using System.IO;
using System.Collections.Generic;

namespace WebThreadTest
{
    public class FileConvertSwf
    {
        //保存所有文件名
        private static List<string> fileList;

        //可以打印的文件格式
        private List<string> printFileFormat = new List<string>() { ".doc", ".docx", ".xlsx", ".xls", ".ppt" };

        public FileConvertSwf()
        {
            fileList = new List<string>();
        }

        /// <summary>
        /// 将文件转化为swf文件
        /// 将swf文件保存到当前目录下
        /// </summary>
        /// <param name="filePath">原文件路径</param>
        public void ConvertToSwf(string filename)
        {
            //获取文件后缀名
            string fileExtension = Path.GetExtension(filename);

            //是否可以打印
            if (fileExtension != null && printFileFormat.Contains(fileExtension.ToLower()))
            {

                int extensionIndex = filename.LastIndexOf(fileExtension);

                //获取文件前缀名
                string fileBeforeExtension = filename.Remove(extensionIndex);

                //swf文件名
                string targetFilename = fileBeforeExtension + ".swf";

                FileInfo file = new FileInfo(targetFilename);

                //不存在才转化
                if (!file.Exists)
                {
                    //使用Print2Flash3服务
                    IServer server = new Server();

                    //设置默认打印机
                    server.SetP2FPrinterAsDefault();

                    //文件转化
                    server.ConvertFile(@filename, @targetFilename, null, null, null);
                }
            }

        }

        /// <summary>
        /// 获取某个目录下的所有文件及子目录下的所有文件
        /// </summary>
        /// <param name="dirPath">目录路径</param>
        public void GetFilename(string dirPath)
        { 
            //当前目录
            DirectoryInfo dir = new DirectoryInfo(dirPath);

            //当前目录下的所有文件
            FileInfo[] files = dir.GetFiles();

            foreach (var f in files)
            {
                //保存到文件名集合中
                fileList.Add(f.FullName);
                
                //文件转换
                ConvertToSwf(f.FullName);
            }

            //获取当前目录下的子目录下的所有文件
            DirectoryInfo[] dirs = dir.GetDirectories();

            foreach (var d in dirs)
            {
                //递归获取文件名
                GetFilename(d.FullName);
            }
        }

        public List<string> GetFileNameList()
        {
            return fileList;
        }
        

    }
}

3.测试代码

using System;
using System.Collections;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using System.Collections.Generic;

namespace WebThreadTest
{
    public partial class testGetFile : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                string dirPath = Server.MapPath(@"/resource/UploadedFiles");
                FileConvertSwf fcSwf = new FileConvertSwf();
                fcSwf.GetFilename(dirPath);
                List<string> fileList = fcSwf.GetFileNameList();

                foreach (var f in fileList)
                {
                    Response.Write(f);
                    Response.Write("<br />");
                }
            }
        }
    }
}

4.html页面显示swf格式
