<table align="left" border="0" cellpadding="0" cellspacing="0" width="100%" class="columnWrapper displayOff">
<tbody>
<tr>
-- and so on
</body>
</html>
我尝试过：
var filepath = HttpContext.Current.Server.MapPath（〜/ Assets / TransactionEmailFiles / cd.html）;
string htmlContent = File.ReadAllText（filepath ）;
var html = htmlContent;
string pattern1 = @<！ - 。* - >;
string input = html;
string replacement =;
Regex rgx = new Regex（pattern1）;
string result1 = rgx.Replace（输入，替换）;
What I have tried:
var filepath=HttpContext.Current.Server.MapPath("~/Assets/TransactionEmailFiles/cd.html");
string htmlContent = File.ReadAllText(filepath);
var html = htmlContent ;
string pattern1 = @"<!--.*-->";
string input = html;
string replacement = " ";
Regex rgx = new Regex(pattern1);
string result1 = rgx.Replace(input, replacement);
推荐答案
缺少正确的正则表达式模式：
You lack the correct regex pattern:
<!--(.|\n)*-->
请参阅演示：
see demo:
using System;
using System.Text.RegularExpressions;
public class Program
{
public static void Main()
{
string pattern1 = @"<!--(.|\n)*-->";
string input = @"<td valign=""top"" class=""mcnTextBlockInner"" style=""background-color:#ffffff;"">
<!--[if gte mso 9] |(IE)]>
<table align=""center"" border=""0"" cellspacing=""0"" cellPadding=""0"" width=""100%"" style=""width:100%;""><tr>
<td align=""left"" valign=""top"" width=""00%"" style=""width:100%;""><![endif]-->
<table align=""left"" border=""0"" cellpadding=""0"" cellspacing=""0"" width=""100%"" class=""columnWrapper displayOff"">
<tbody>
<tr>";
string replacement = " ";
Regex rgx = new Regex(pattern1);
string result1 = rgx.Replace(input, replacement);
Console.WriteLine(result1);
}
}输出减去评论：
<td valign="top" class="mcnTextBlockInner" style="background-color:#ffffff;">
<table align="left" border="0" cellpadding="0" cellspacing="0" width="100%" class="columnWrapper displayOff">
