如何检查开始/结束字，长空格分隔字符串

Question

我有一个字符串数组即

string[] input_Text = new string[] { "i am wanting to take admission in the univeristy of the islamabad", "we are enjoying all the talent here at the city of atlanta", "what are you doing there" }; 

和停用词阵列即

string[] stopWords = new string[] { " are ", " am ", " all ", " at ", " here ", " i ", " in ", " of ", " take ", " the ", " there ", " to ", " what ", " we ", " you " }; 

我有“，以取代INPUT_TEXT禁用词“（whiteSpace），但问题是，我在stopwords数组中使用”i“，并且文本中包含”i“，意味着在”i“开始处没有空白。所以问题是文本中的开始和结束字符串与stopWords不匹配，所以无法删除这些字词。我正在使用的循环是...

for (int i = 0; i < input_Text.Count(); i++) 
{ 
    for (int j = 0; j < stopWords.Count(); j++) 
    { 
     input_Text[i] = input_Text[i].Replace(stopWords[j], " "); 
    } 
    } 

任何建议将不胜感激。

鉴于你的数据，你可以Replace前添加一个空格字符的开始和结束input_Text，之后将其删除：

string s = " " + input_Text[i] + " "; 
s = s.Replace(stopWords[j], " "); 
input_Text[i] = s.Substring(1, s.Length - 2); 

效率不高，但应该能正常运行。
