如何<strong>从C＃中的字符串中</strong>删除双HTML <strong>标记</strong>

Question

I want to made search on my ASP.NET MVC 3 site, so for search I have to find matched patterns and in that words replace matched part with the same part in bold(I us efor that html <strong> tag).

So I have this in my controller

        string[] words=content.Split(' ');
        foreach (Thread thread in context.Threads)
        {
            foreach (string word in words)
            {
                if (thread.Title.ToLower().Contains(word.ToLower()))
                {
                    thread.Title=Regex.Replace(thread.Title,word,String.Format("<strong>{0}</strong>","$0"),RegexOptions.IgnoreCase);
                }
            }

         }

So, if I search new thread a It will find thread like this New thrEAd .

But in html it makes my string like that

<strong>New</strong> <strong>thrE<strong>A</strong>d</strong>

So I want to remove strong tag from a, because it makes a double-bold... How can I do that?

And if you have interesting ways to do my search, I will glad to hear your suggestions too.

Answer 1

您可以通过检查搜索词中是否包含其他任何词来清理搜索词：

var cleanWords = words.Where(w => !words.Any(w2 => w2.Contains(w));

Answer 2

Try this:

IEnumerable<string> enumerableWords = content.Split(' ').Distinct();
string[] words = enumerableWords.ToArray();
foreach (Thread thread in context.Threads) {
    string result = thread.Title;
    foreach (string word in words) {
        result = Regex.Replace(result, String.Format(@"\b{0}\b", word), String.Format(@"<strong>{0}</strong>", word), RegexOptions.IgnoreCase);
    }
    thread.Title = result;
}
