C＃從語音標記中獲取語音

Question

我正在嘗試使用C＃和Regex在RichTextBox中進行語音識別，以便當用戶單擊「查找語音」時，所有語音標記和中的語音都將突出顯示藍色。但是，我不太確定如何將內部演講與正則表達式結合起來，因爲我目前所能做的就是突出顯示語音標記。

public void FindSpeech() 
{ 

    Regex SpeechMatch = new Regex("\""); 

    TXT.SelectAll(); 
    TXT.SelectionColor = System.Drawing.Color.Black; 
    TXT.Select(TXT.Text.Length, 1); 
    int Pos = TXT.SelectionStart; 

    foreach (Match Match in SpeechMatch.Matches(TXT.Text)) 
    { 
      TXT.Select(Match.Index, Match.Length); 
      TXT.SelectionColor = System.Drawing.Color.Blue; 
      TXT.SelectionStart = Pos; 
      TXT.SelectionColor = System.Drawing.Color.Black; 
    } 
} 

Answer 1

試試這個：

Regex SpeechMatch = new Regex("\".+?\""); 

Answer 2

您可以使用此模式。主要的興趣在於它可以匹配，引號裏的轉義引號：

Regex SpeechMatch = new Regex(@"\"(?>[^\\\"]+|\\{2}|\\(?s).)+\""); 

圖案的詳細資料：

\"    # literal quote 
(?>   # open an atomic(non-capturing) group 
    [^\\\"]+ # all characters except \ and " 
    |   # OR 
    \\{2}  # even number of \ (that escapes nothing) 
    |   # OR 
    \\(?s). # an escaped character 
)+    # close the group, repeat one or more times (you can replace + by * if you want) 
\"    # literal quote
