检测特定标记的字符串。 C＃ [英] Detect particular tokens in a string. C#
问题描述
我有一个非常大的字符串（HTML），并在此HTML存在这样的情况他们都以＃和＃
I have a very large string (HTML) and in this HTML there is particular tokens where all of them starts with "#" and ends with "#"
简单的如
<html>
<body>
<p>Hi #Name#, You should come and see this #PLACE# - From #SenderName#</p>
</body>
</html>
我需要一个code，能够检测到这些标记，并把它放在一个列表。 0 - ＃姓名＃ 1 - ＃将＃ 2 - #SenderName＃
I need a code that will detect these tokens and will put it in a list. 0 - #Name# 1 - #Place# 2 - #SenderName#
我知道，我可以使用正则表达式也许，反正你有一些想法，这样做呢？
I know that I can use Regex maybe, anyway have you got some ideas to do that?
推荐答案
是的，你可以使用普通的EX pressions。
Yes you can use regular expressions.
string test = "Hi #Name#, You should come and see this #PLACE# - From #SenderName#";
Regex reg = new Regex(@"#\w+#");
foreach (Match match in reg.Matches(test))
{
Console.WriteLine(match.Value);
}
正如你可能已经猜到了\ W表示任何字母数字字符。的+表示，它可能会出现1次或多次。你可以在这里找到更多的信息 MSDN文档（用于.NET 4.你会发现其他版本那里也）。
As you might have guessed \w denotes any alphanumeric character. The + denotes that it may appear 1 or more times. You can find more info here msdn doc (for .Net 4. You'll find other versions there as well).
