C＃ - 如何計算.RTF/.TXT文件中的單詞和字母？

Question

標題所說的一切..

搜查谷歌和＃1，並沒有發現類似的東西..

Answer 1

爲.txt文件，你可以使用正則表達式\b\w+\b。它將匹配單詞的所有事件，如：

var count = Regex.Matches(input, @"\b\w+\b").Count; 

要計算字母：

int count = input.Count(char.IsLetter); 

Answer 2

static void Main() 
{ 
    const string t1 = "To be or not to be, that is the question."; 
    Console.WriteLine(WordCounting.CountWords1(t1)); 
    Console.WriteLine(WordCounting.CountWords2(t1)); 

    const string t2 = "Mary had a little lamb."; 
    Console.WriteLine(WordCounting.CountWords1(t2)); 
    Console.WriteLine(WordCounting.CountWords2(t2)); 
}
