拆分字符串 C#

Question

我想根據字符和字符串（如 ( , . ; and or though but等) 拆分字符串。
原字符串： "This movie is great. I like the story, acting is nice and direction is perfect but music is not good."
結果：
This movie is great
I like the story
acting is nice
direction is perfect
music is not good

我試過這個。

string test = "This movie is great. I like the story, acting is nice and direction is perfect but music is not good.";
var splittC = Regex.Split(test, ",");
foreach(var a in splittC){
    var splittD = Regex.Split(test, "."); 
    foreach(var b in splittD){
       var splittA = Regex.Split(test, "and"); 
    }
}// and so on....

它需要這么多循環。
如果此字符串中沒有逗號，則不會檢查其他字符。 如何解決這些問題。 請幫忙。

Answer 1

String.Split允許使用string[]參數。

嘗試這個：

string test = "This movie is great. I like the story, acting is nice and direction is perfect but music is not good.";
var splitVals = test.Split(new string[] { ",", ".", ";", " and ", " or ", " though ", " but ", " etc. "}, StringSplitOptions.RemoveEmptyEntries);

解析自然語言很困難，因為計算機不理解上下文。 如果他們可以的話，我們可以像他們是人一樣與他們交談。

有時句子中的and和句號不是分隔符，有時句子不以大寫字母開頭。

“一加二，三加四。” 唱歌的音樂家。

為了做好這項工作，我建議你要么

(a) 非常嚴格地控制允許的輸入，或

(b) 使用自然語言解析庫，例如原生的 SharpNLP，或者您可以從 C# 調用 NLTK。 NLTK 可能是最好的，但有時也會失敗。 由於其機器學習所需的訓練數據，它的大小也為 5 GB。

要完成這項工作，您需要使用詞法分析器解析句子，然后處理生成的對象。 示例關鍵字詞法項是“and”、“,”等。然后可以連接關鍵字項之間的已解析項中的其余文本並發送到輸出。

嘗試使用我寫的這個簡單的正則表達式可能對你有幫助：

var splitRegex=@"\.|\,|\;|(?:\sand\s)|(?:\sor\s)|(?:\sthough\s)|(?:\sbut\s)";
var splittC = Regex.Split(test, splitRegex);
...

結果是： 它可能需要一些修改才能在所有情況下工作。

string test = "This movie is great. I like the story, acting is nice and direction is perfect but music is not good.";
var splitVals = test.Split(new string[] 
{   ",", ".", ";", " and ", " or ",
    " though ", " but ", " etc. "
},StringSplitOptions.RemoveEmptyEntries);
