word预览与打印

解决⽅案：1. 在后台把word⽂件转化成pdf，在前台⽤iframe显⽰pdf,打印iframe，即可。优点：⽤户体验好。缺点：不⽀持IE。实现 ：引⽤netoffice组件主要代码：

ation wordApplication = new ation(); nt pDoc = (path); te(); (pdf, atPDF); (); e();

2. 在后台把word转化⾯html，读取html⽂本，增加打印脚本，输出到前台。优点：浏览器⽀持的好。缺点：⽤html显⽰word，不是太好看。实现 ：引⽤：主要代码： public class WordToHtmlConverter { ///

/// Convert Docx to Html ///

/// source file full name /// htmlstring public static string ToHtml(string source) { var htmlString = ; var file = new FileInfo(source); byte[] bytes = lBytes(me); using (MemoryStream memoryStream = new MemoryStream()) { (bytes, 0, ); using (var wDoc = (memoryStream, true)) { var imageFolder = ing(0, - 5) + "_files"; int imageCounter = 0;

HtmlConverterSettings settings = new HtmlConverterSettings() { AdditionalCss = "body { margin: 1cm auto; max-width: 20cm; padding: 0; }", PageTitle = "新系统", FabricateCssClasses = true, CssClassPrefix = "pt-", RestrictToSupportedLanguages = false, RestrictToSupportedNumberingFormats = false, ImageHandler = imageInfo => { DirectoryInfo localDirInfo = new DirectoryInfo(imageFolder); if (!) (); ++imageCounter; string extension = ('/')[1].ToLower(); ImageFormat imageFormat = null; if (extension == "png") imageFormat = ; else if (extension == "gif") imageFormat = ; else if (extension == "bmp") imageFormat = ; else if (extension == "jpeg") imageFormat = ; else if (extension == "tiff") { // Convert tiff to gif. extension = "gif"; imageFormat = ; } else if (extension == "x-wmf") { extension = "wmf"; imageFormat = ; } // If the image format isn't one that we expect, ignore it, // and don't return markup for the link. if (imageFormat == null) return null; string imageFileName = imageFolder + "/image" + ng() + "." + extension; try { (imageFileName, imageFormat); } catch (alException) { return null; } string imageSource = + "/image" + ng() + "." + extension; XElement img = new XElement(, new XAttribute(, imageSource), leAttribute, t != null ? new XAttribute(, t) : null); return img; } }; XElement htmlElement = tToHtml(wDoc, settings); // Produce HTML document with declaration to tell the browser we are using HTML5. var html = new XDocument(new XDocumentType("html", null, null, null), htmlElement); htmlString = ng(eFormatting); } } return htmlString; } } public string NoticePrint(NoticeResult model) { // 第⼀步，⽣成新的doc⽂档，替换模板⽂件中的标签，这⾥⽤的是NPOI，这个⽅法就不显⽰了，没什么东西。 var path = FileName(model); // 第⼆步，把doc⽂件，转化成html⽂件 var html = (path); // 第三步，对html追加script脚本 var result = html + GetPrintScript(); // 第四步，返回 return result; } private string GetPrintScript() { return @""; }Controller Code:public ActionResult Print(NoticeResult model) { var result = new Response(); if (model != null) { var html = Print(model);

return Content(html, "text/html"); } = "打印参数异常"; return Json(result); }

代码有删减，不能拿来直接⽤
