c# - 使用 C# 从数组中的单词中删除字符串中的单词

Question

我需要根据一组单词从字符串中删除单词:

我要删除的词:

DE DA DAS DO DOS AN NAS NO NOS EM E A AS O OS AO AOS P LDA AND

如果我收到如下字符串:

编辑:这个字符串已经从任何符号中“清除”

THIS IS AN AMAZING WEBSITE AND LAYOUT

结果应该是:

THIS IS AMAZING WEBSITE LAYOUT

到目前为止我有:

public static string StringWordsRemove(string stringToClean, string wordsToRemove)
{
    string[] splitWords = wordsToRemove.Split(new Char[] { ' ' });

    string pattern = "";

    foreach (string word in splitWords)
    {
        pattern = @"\b" + word + "\b";
        stringToClean = Regex.Replace(stringToClean, pattern, "");
    }

    return stringToClean;
}

但它并没有删除单词，知道吗？

我不知道我使用的是不是最有效的方法，也许把单词放在一个数组中只是为了避免它们一直被拆分？

谢谢

Answer 1

private static List<string> wordsToRemove =
    "DE DA DAS DO DOS AN NAS NO NOS EM E A AS O OS AO AOS P LDA AND".Split(' ').ToList();

public static string StringWordsRemove(string stringToClean)
{
    return string.Join(" ", stringToClean.Split(' ').Except(wordsToRemove));
}

处理标点符号的修改:

public static string StringWordsRemove(string stringToClean)
{
    // Define how to tokenize the input string, i.e. space only or punctuations also
    return string.Join(" ", stringToClean
        .Split(new[] { ' ', ',', '.', '?', '!' }, StringSplitOptions.RemoveEmptyEntries)
        .Except(wordsToRemove));
}
