1、C# 仿百度文库在线查看功能资料发布到查看分为三个步骤:1、上传文件（doc、xls、ppt）转换成Pdf文件2、Pdf文件转换成swf文件3、把 swf 文件显示出来第一步：把上传的文件（doc、xls、ppt）转换成Pdf文件。直接在后台用代码转 换，新建一个类，这一步没有什么特殊的要求，转换代码如下：using System;using System.Data;usi ng System.C on figura tion;using System.Web;using System.Web.Security;us ing System.Web.UI;using System.Web.Ul.
