正則表達式表達不

目前有一個控制檯應用程序，從0365 Outlook帳戶獲取電子郵件，我使用Outlook API 2.0

從HTML字符串刪除內聯CSS問題

我正在使用api訪問電子郵件的正文，但正文是以html字符串形式出現的。我正在使用我的去正則表達式功能，它將刪除html標記，但outlook添加一個CSS類到他們的Html基本上使我的正則表達式過時。

代碼

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;

    {margin:1.0in 1.0in 1.0in 1.0in} 
div.WordSection1 
    {} 
--> 
</style> 
</head> 
<body lang="EN-US" link="#0563C1" vlink="#954F72"> 
<div class="WordSection1">

目的

結果

我需要從字符串能夠帶html標籤，並且還刪除出來的css類尋找身體的地方。

順便說一句，你可能要考慮更換爲空（白）的空間，這是它代表的（不是空的）。 – JuanR

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

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