Question

我必须在一个包含40多个字母的句子中拆分这个词......

   **For Example:**

    Hi Pranesh....I am new to C# asp.Net...**pranuvideotitlepranuvideotitlepranutitleppranuvideotitlepranuvideotitlepranutitlep**

我想找到包含超过40个字母的单词，并希望删除单词中的字母，使其仅包含40个字母....

由于

Answer 1

首先找到包含超过40个字母的所有单词

var a = content.Split(' ').Where(s => s.Length > 40);

然后通过forech循环删除

Answer 2

我喜欢扩展方法！

我会做这样的事情：

 public static string Truncate(this string s, int maxLength) {
        if (string.IsNullOrEmpty(s) || maxLength <= 0)
            return string.Empty;
        else if (s.Length > maxLength)
            return s.Substring(0, maxLength) + "&hellip;";
        else
            return s;
 }

编辑：问题不是很清楚。如果你想删除少于40个字符的所有单词，你可以这样：

 public string FindBigWords(string s) {
        Regex regEx = new Regex(@"\s+");
        string[] tokens = regEx.Split(s);
        string ret = "";
        foreach (var t in tokens) {
            if (t.Length > 40)
                ret += t;
        }
        return ret;
 }

注意我没有测试过上面的内容，效率不高。可能想要改变它至少使用stringbuilder。

这样的东西？

string data = @"Hi Pranesh....I am new to C# asp.Net...**pranuvideotitlepranuvideotitlepranutitleppranuvideotitlepranuvideotitlepranutitlep**";
string[] split = Regex.Split(data, @"\s");
foreach(string word in split)
{
    if (word.Length > 40)
    {
        data = data.Replace(word, word.Substring(0, 40));
    }
}

怎么样

        static string FourtyLetterWords(string s)
        {
            var splitString = GetWords(s);
            return string.Join("", splitString.Select(u => u.Count() >= 40 ? u.Substring(0, 40) : u));
        }

        private static List<string> GetWords(string s)
        {
            var stringList = new List<string>();
            StringBuilder currentWord = new StringBuilder();
            for (int i = 0; i < s.Length; i++)
            {
                if(char.IsLetter(s[i]))
                {
                    currentWord.Append(s[i]);
                }
                else
                {
                    stringList.Add(currentWord.ToString());
                    currentWord.Clear();
                    stringList.Add(s[i].ToString());
                }
            }
            return stringList;
        }

使用 -

调用

string test = FourtyLetterWords(@"Hi Pranesh....I am new to C# asp.Net...**pranuvideotitlepranuvideotitlepranutitleppranuvideotitlepranuvideotitlepranutitlep**");

返回 - “你好Pranesh ......我是C＃asp.Net的新手...... pranuvideotitlepranuvideotitlepranutitle ”

Answer 5

public static string TruncateLongWords(this string sentence, int maximumWordLength)
{
    var longWords = sentence.Split(' ').Where(w => w.Length > maximumWordLength);

    foreach (var longWord in longWords)
    {
        sentence = sentence.Replace(longWord, longWord.Substring(maximumWordLength));
    }

    return sentence;
}

Answer 6

var a = content.Split（''）。Where（s =＆gt; s.Length＆lt; = 40）;

这将给出截断的内容。您可以在var对象上使用ToArray（）来获取字符串数组。
