正则表达式表达不

目前有一个控制台应用程序，从0365 Outlook帐户获取电子邮件，我使用Outlook API 2.0

从HTML字符串删除内联CSS问题

我正在使用api访问电子邮件的正文，但正文是以html字符串形式出现的。我正在使用我的去正则表达式功能，它将删除html标记，但outlook添加一个CSS类到他们的Html基本上使我的正则表达式过时。

代码

string body = "<html> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"> 
<meta content="text/html; charset=us-ascii"> 
<meta name="Generator" content="Microsoft Word 15 (filtered medium)"> 
<style> 
<!-- 
@font-face 
    {font-family:"Cambria Math"} 
@font-face 
    {font-family:Calibri} 
p.MsoNormal, li.MsoNormal, div.MsoNormal 
    {margin:0in; 
    margin-bottom:.0001pt; 
    font-size:11.0pt; 
    font-family:"Calibri",sans-serif} 
a:link, span.MsoHyperlink 
    {color:#0563C1; 
    text-decoration:underline} 
a:visited, span.MsoHyperlinkFollowed 
    {color:#954F72; 
    text-decoration:underline} 
span.EmailStyle17 
    {font-family:"Calibri",sans-serif; 
    color:windowtext} 
.MsoChpDefault 
    {font-family:"Calibri",sans-serif} 
@page WordSection1 
    {margin:1.0in 1.0in 1.0in 1.0in} 
div.WordSection1 
    {} 
--> 
</style> 
</head> 
<body lang="EN-US" link="#0563C1" vlink="#954F72"> 
<div class="WordSection1"> 
<p class="MsoNormal">&nbsp;</p> 
</div>

</body> 
</html> 
"; 
string viewString1 = Regex.Replace(body, "<.*?>", string.Empty); 
string viewString12 = viewString1.Replace("&nbsp;", string.Empty);

从我的正则表达式

<!-- 
@font-face 
    {font-family:"Cambria Math"} 
@font-face 
    {font-family:Calibri} 
p.MsoNormal, li.MsoNormal, div.MsoNormal 
    {margin:0in; 
    margin-bottom:.0001pt; 
    font-size:11.0pt; 
    font-family:"Calibri",sans-serif} 
a:link, span.MsoHyperlink 
    {color:#0563C1; 
    text-decoration:underline} 
a:visited, span.MsoHyperlinkFollowed 
    {color:#954F72; 
    text-decoration:underline} 
span.EmailStyle17 
    {font-family:"Calibri",sans-serif; 
    color:windowtext} 
.MsoChpDefault 
    {font-family:"Calibri",sans-serif} 
@page WordSection1 
    {margin:1.0in 1.0in 1.0in 1.0in} 
div.WordSection1 
    {} 
-->

目的

结果

我需要从字符串能够带html标签，并且还删除出来的css类寻找身体的地方。

顺便说一句，你可能要考虑更换为空（白）的空间，这是它代表的（不是空的）。 – JuanR

您可以String.Empty与regex option Singleline^{替换（使.匹配新行）}：

string viewString1 = Regex.Replace(body, "<.*?>", string.Empty, RegexOptions.Singleline);
