使用Microsoft的Office组件将文件转换为PDF格式文件,然后再使用pdf2swf转换为swf文件,也就是flash文件在使用FlexPaper展示出来(优点:预览效果能接受,缺点:代码量大)
使用ASPOSE+pdf2swf+FlexPaper
关于ASPOSE大家可以到官网了解,这是款商业收费产品但是免费也可以使用
1、引用dll
这一步的前提是需要去 官网下载 组件
下载之后,进行安装,然后在安装文件夹找到相应的 dll 库文件,然后引用到自己的项目中去
比如我要是想Word的在想浏览功能,那么我需要下载的组件是 Aspose.Word,然后安装,最后找到 dll 引用
2. 编写相应的转换方法,AsposeUtil 中的方法可根据具体自己需要提取部分,可做相应修改调整后使用

另:项目使用,根据需要有一些的改动
这里还需要下载 swf 转换工具 swfTools 官网下载 安装,然后在安装目录找到 pdf2swf.exe,我是放在 项目的 bin 文件夹下面,其实可以自己放在任意的位置,只是使用的时候填好路径。
封装一个传参数的类:
public class FlexPaper { public int ID { get; set; } public string SwfFileName { get; set; } public string PdfFile { get; set; } public string SwfFile { get; set; } }
转换的工具类:
(1). Word 转Pdf 的帮助类
public class WordHelper { /// <summary> /// Wrod文档转换为PDF文件 /// </summary> /// <param name="sourceFileName">需要转换的Word全路径</param> /// <param name="targetFileName">目标文件全路径</param> /// <returns>转换是否成功</returns> public static bool ConvertDocToPdF(string sourceFileName, string targetFileName) { try { using (System.IO.Stream stream = new System.IO.FileStream(sourceFileName, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite)) { Document doc = new Document(sourceFileName); doc.Save(targetFileName, Aspose.Words.SaveFormat.Pdf); } } catch (Exception ex) { } return System.IO.File.Exists(targetFileName); }
(2). pdf转 swf 的帮助类
public class FlexPaperEntity { public List<FlexPaper> GetSwfFile(FlexPaper fp) { //string TemporaryDirectory = "~/Temp/"; //string fID = fp.ID.ToString(); string filePdf = fp.PdfFile;// TemporaryDirectory + fID + ".pdf"; string fileName = Guid.NewGuid().ToString(); string fileswf = fp.SwfFile; //TemporaryDirectory + fileName + ".swf"; using(System.Diagnostics.Process p =new System.Diagnostics.Process()) { //获取 执行转换功能的文件路径 p.StartInfo.FileName = HttpContext.Current.Server.MapPath("~/bin/pdf2swf.exe"); //p.StartInfo.Arguments = " -t " + HttpContext.Current.Server.MapPath(filePdf) + " -s flashversion=9 -o " + HttpContext.Current.Server.MapPath(fileswf); //转换命令 p.StartInfo.Arguments = " -t " + filePdf + " -s flashversion=9 -o " +fileswf; //相应参数的设置 p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = false; p.StartInfo.CreateNoWindow = true; p.StartInfo.UseShellExecute = false; //开始执行 p.Start(); p.WaitForExit(); } //返回保存的路径 List<FlexPaper> oo = new List<FlexPaper>(); oo.Add(new FlexPaper { SwfFile = "/Temp/" + fp.SwfFileName + ".swf" }); return oo; } }
写了一个测试用的 ashx 一般处理程序
public class GetSwf : IHttpHandler { public void ProcessRequest(HttpContext context) { //int fileID = Convert.ToInt32(context.Request["fileID"]); string docFile = context.Server.MapPath("~/Temp/129.doc"); string pdfFile = context.Server.MapPath("~/Temp/129.pdf"); WordHelper.ConvertDocToPdF(docFile, pdfFile); string fileName = Guid.NewGuid().ToString(); string swfFile = context.Server.MapPath("~/Temp/" + fileName + ".swf"); FlexPaper fp = new FlexPaper() {SwfFileName=fileName, PdfFile = pdfFile, SwfFile = swfFile }; FlexPaperEntity ent = new FlexPaperEntity(); List<FlexPaper> lis = ent.GetSwfFile(fp); context.Response.Write(DataHelper.JsonSerialize(lis)); } public bool IsReusable { get { return false; } } }

附:整个测试项目的文件结构
注:ppt转换PDF如果有问题,可再联系....
由于试用版限制只能转换5页文件,所以有可能的话就使用 aspose 破解版
