Asp.net实现直接在浏览器预览Word Excel PDF Txt文件（附源码）

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publicstaticvoidPriview(System.Web.UI.Pagep,stringinFilePath,stringoutDirPath="")

} 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();}

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();}

WordPreview.cs Word预览类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 Word15.0MicrosoftExcel15.0

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中打开源码下载
