Welcome

首页 / 网页编程 / ASP.NET / Asp.net实现直接在浏览器预览Word、Excel、PDF、Txt文件(附源码)

1.功能说明
输入文件路径,在浏览器输出文件预览信息,经测试360极速(Chrome)、IE9/10、Firefox通过
2.分类文件及代码说明
DemoFiles 存放可测试文件
Default.aspx  启动页
ExcelPreview.cs  Excel预览类
public static void Priview(System.Web.UI.Page p, string inFilePath, string outDirPath = ""){Microsoft.Office.Interop.Excel.Application excel = null;Microsoft.Office.Interop.Excel.Workbook xls = null;excel = new Microsoft.Office.Interop.Excel.Application();object missing = Type.Missing;object trueObject = true;excel.Visible = false;excel.DisplayAlerts = false;string randomName = DateTime.Now.Ticks.ToString(); //output fileNamexls = excel.Workbooks.Open(inFilePath, missing, trueObject, missing,missing, missing, missing, missing, missing, missing, missing, missing,missing, missing, missing);//Save Excel to Htmlobject format = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;Workbook wsCurrent = xls;//(Workbook)wsEnumerator.Current;String outputFile = outDirPath + randomName + ".html";wsCurrent.SaveAs(outputFile, format, missing, missing, missing, missing, XlSaveAsAccessMode.xlNoChange, missing, missing, missing, missing, missing);excel.Quit();//Open generated HtmlProcess process = new Process();process.StartInfo.UseShellExecute = true;process.StartInfo.FileName = outputFile;process.Start();}
4.PDfPreview.cs   Pdf预览类
public static void Priview(System.Web.UI.Page p, string inFilePath){p.Response.ContentType = "Application/pdf";string fileName = inFilePath.Substring(inFilePath.LastIndexOf("\") + 1);p.Response.AddHeader("content-disposition", "filename=" + fileName);p.Response.WriteFile(inFilePath);p.Response.End();}
5.TextFilePreview.cs  文本文件预览类
 public static void Preview(System.Web.UI.Page p, string inFilePath){string fileName = inFilePath.Substring(inFilePath.LastIndexOf("\") + 1);p.Response.ContentType = "text/plain";p.Response.ContentEncoding = System.Text.Encoding.UTF8; //保持和文件的编码格式一致p.Response.AddHeader("content-disposition", "filename=" + fileName);p.Response.WriteFile(inFilePath);p.Response.End();}
6. WordPreview.cs  Word预览类
7.Readme.txt  说明了基本功能及引用Com组件的方法(首先需要安装office),需引入的组件包括
  Microsoft Word 15.0
  Microsoft Excel 15.0


  预览效果
1、Word


2、Excel 


3、Pdf


4、Txt


未解决的问题
Pdf、txt文件只能在当前页显示,并导致后退键无效,请各位帮忙解决此两种文件和doc、xls一样在新的tab中打开
