If you want to parse html in c# the best way is to use Html agility pack : 如果要使用C＃解析html，最好的方法是使用HTML敏捷包：
https://htmlagilitypack.codeplex.com/ https://htmlagilitypack.codeplex.com/
HtmlDocument document = new HtmlDocument();
document.Load(@"C:\yourfile.html")
HtmlNode nodesToRemove= document .DocumentNode.SelectNodes("//div[@class='container']").ToList();
foreach (var node in nodesToRemove)
node.Remove();

The proper way (I suppose) to do this is via built in Gecko DOM classes and methods. 正确的方法（我想）是通过内置的Gecko DOM类和方法实现的。
So, in your case something like: 因此，在您的情况下，例如：
var containers = yourDocument.GetElementsByClassName("container");
//this returns an IEnumerable of elements with this class. If you only ever gonna have one, you can do it like that:
var yourContainer = containers.FirstOrDefault();
yourContainer.Parent.RemoveChild(yourContainer);
Obviously, you can also do loops etc. 显然，您也可以执行循环等。

Well, with the help of regex, you can remove your desired div 好吧，借助正则表达式，您可以删除所需的div
var data = "<body>\n<div class=\"head\">...</div>\n" +
"<div class=\"container\">...</div>\n" +
"<div class=\"foot\">...</div>\n</body>";
var rxStr = "<div[^<]+class=([\"'])container\\1.*</div>";
var rx = new System.Text.RegularExpressions.Regex (rxStr,
System.Text.RegularExpressions.RegexOptions.IgnoreCase);
var nStr = rx.Replace (data, "");
Console.WriteLine (nStr);
This will reduce your string to 这将减少您的字符串
<body>
<div class="head">...</div>
<div class="foot">...</div>
</body>
