如何檢查開始/結束字，長空格分隔字符串

Question

我有一個字符串數組即

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" }; 

和停用詞陣列即

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禁用詞「（whiteSpace），但問題是，我在stopwords數組中使用」i「，並且文本中包含」i「，意味着在」i「開始處沒有空白。所以問題是文本中的開始和結束字符串與stopWords不匹配，所以無法刪除這些字詞。我正在使用的循環是...

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], " "); 
    } 
    } 

任何建議將不勝感激。

鑑於你的數據，你可以Replace前添加一個空格字符的開始和結束input_Text，之後將其刪除：

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

效率不高，但應該能正常運行。
