一、c#代码将html样式文件转为word文档
首先有个这样的需求,将以下网页内容下载为word文件。

样式展示:
第一步:封装一个方法
1:在控制器biddingnoticemanagecontroller创建一个downbiddingnoticemodal方法。(采用的mvc模式)
2:根据id查询当前中标信息(ef)
3:建一个中标通知书的html模板页(数据字段自定义占位符)
3-1:注:html模板中不需要<html>、<head>、<title>、<body>等标签。只是单纯的div布局标签
3-2:布局标签中的样式必须是内联,就是写在标签中,不能写在外部.css中。
4:通过stream、streamreader两个类来读取这个模板文件(返回的是html字符串)。
5:2中查询出数据(对应字段)替换4中返回的html字符串中的占位符。
6:关键代码

stringbuilder sb = new stringbuilder(); sb.append( "<html xmlns:v=\"urn:schemas-microsoft-com:vml\" xmlns:o=\"urn:schemas-microsoft-com:office:office\" xmlns:w=\"urn:schemas-microsoft-com:office:word\" xmlns:m=\"http://schemas.microsoft.com/office/2004/12/omml\"xmlns = \"http://www.w3.org/tr/rec-html40\">" ); sb.append(html); sb.append( "</html>" ); |
7:用法:在页面前端写一个a标签指向这个方法即可下载为word文件了。

二、c# 将word文档转换为html
日常生活中,我们总是在word中进行文字的编辑,它不仅能够保存text文本,还可以保存文本的格式等等。那么如果我要将一word文档上的内容展示在网页上,该怎么做呢?这里我提供了一个小工具,你可以将word转换为html,需要显示的话,可以直接访问该html,废话不多说,下面看代码。
页面代码:

< span style = "font-size:18px;" >< div > < input id = "file1" type = "file" runat = "server" /> < asp:button id = "btnconvert" runat = "server" text = "转换" onclick = "btnconvert_click" /> </ div ></ span > |

效果图:
转换后的html文件
这样就可以简单的在html中展示word文档中的内容,而不需要在自己进行编辑了。当然,如果有需要的话,可以将转换的html的路径存入数据库,根据不同的条件直接进行访问。
