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 fileName xls = excel.Workbooks.Open(inFilePath, missing, trueObject, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing); //Save Excel to Html object 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 Html Process 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
