1.html转pdf
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
using System; using System.Collections.Generic; using System.Linq; using System.Web; /// <summary> /// HtmlToPdf 的摘要说明 /// 使用前需要安装事项 /// 安装软件见 Lib/wkhtmltox-0.12.4_msvc2015-win64.exe /// </summary> public class HtmlToPdf { /// <summary> /// 根据实际安装目录修改 /// </summary> private string exePath = @"C:Program Fileswkhtmltopdfinwkhtmltopdf.exe"; public HtmlToPdf() { // // TODO: 在此处添加构造函数逻辑 // } public bool ToPdf(string url,string outPdfPath) { try { string path = url + " " + outPdfPath; //执行wkhtmltopdf.exe System.Diagnostics.Process p = System.Diagnostics.Process.Start(exePath, path); //若不加这一行,程序就会马上执行下一句而抓不到文件发生意外:System.IO.FileNotFoundException: 找不到文件 ''。 p.WaitForExit(); return true; } catch (Exception) { } return false; //因为Web 是多线程环境,避免甲产生的文件被乙下载去,所以档名都用唯一 // string fileNameWithOutExtention = Guid.NewGuid().ToString(); } }
使用需要下载并安装wkhtmltopdf.exe文件
HtmlToPdf pdf = new HtmlToPdf(); var vl = pdf.ToPdf("要保存的url地址需要包含http://xxxxxx", "PDF要保存的文件路径+文件名称");
2.读取html内容
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
/// <summary> /// 读取ht.html文件内容 /// </summary> /// <returns></returns> private string GetBidTempStrng() { StringBuilder sbHtml = new StringBuilder(); // 读取模板替换数据 var path = Server.MapPath("~/contractFile/ht.html"); using (Stream inStream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Read)) using (StreamReader outStream = new StreamReader(inStream, Encoding.Default)) { while (!outStream.EndOfStream) { sbHtml.Append(outStream.ReadLine()); } } var html = sbHtml.ToString(); return html; }
3. webform中将html文件保存为word文件
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
#region 转换为Word文档样式 //Response.ContentType = "application/msword"; Response.ContentType = "application/msword"; //Response.Write(Encoding.UTF8.GetBytes(sb.ToString())); string fileName = "xxx.doc";//客户端保存的文件名 string filePath = Server.MapPath("~/contractFile/ht.html");//路径 //以字符流的形式下载文件 FileStream fs = new FileStream(filePath, FileMode.Open); byte[] bytes = new byte[(int)fs.Length]; fs.Read(bytes, 0, bytes.Length); fs.Close(); //Response.ContentType = "application/octet-stream"; //通知浏览器下载文件而不是打开 Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8)); Response.BinaryWrite(bytes); Response.Flush(); Response.End(); #endregion
4.ie中将文件保存为word
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
<script type="text/javascript" language="javascript"> //指定页面区域内容导入Word function exportToWord(controlId) { var control = document.getElementById(controlId); try { var oWD = new ActiveXObject("Word.Application"); var oDC = oWD.Documents.Add("", 0, 1); var oRange = oDC.Range(0, 1); var sel = document.body.createTextRange(); try { sel.moveToElementText(control); } catch (notE) { alert("导出数据失败,没有数据可以导出。"); window.close(); return; } sel.select(); sel.execCommand("Copy"); oRange.Paste(); oWD.Application.Visible = true; //window.close(); } catch (e) { alert("导出数据失败,需要在客户机器安装Microsoft Office Word(不限版本),将当前站点加入信任站点,允许在IE中运行ActiveX控件。"); try { oWD.Quit(); } catch (ex) { } //window.close(); } } </script>
