Code:

Class Program
{

static void Main (string[] args)
{

Console.WriteLine ("Please copy the article to be counted into the Test1.txt file in the debug directory, press any key to continue");
Console.readkey ();
Frequency ();

}

static private void Frequency ()

List<string> Word = new list<string> ();//An array of words in the article, including repeated words
list<string> Newword = new list<string> ();//The word array in the article, excluding duplicate words
list<int> count = new list<int> ();//Count the number of each word in the article

int n = 0; The total number of words in the file includes duplicate words
Char[] split = {', ', ', '? ', '? ‘, ‘.‘, ‘。 ‘, ‘-‘, ‘—‘, ‘"‘ };
string text = System.IO.File.ReadAllText (@ "Test1.txt");
Composition. AddRange (text. Split (split));

foreach (string compo in composition)
{
if (compo! = "" "" && compo! = null)
{
Word. ADD (compo. ToLower ()); Convert all the words to lowercase letters
}

}

Newword. ADD (Word[0]);

Count. ADD (1);

for (int i = 1; i < n; i++)//Starting with the second word counting
{
int j = 0;

for (j = 0; J < Newword. Count; J + +)//compare with previous words to see if there is the same
{
if (word[i] = = Newword[j])
{
count[j]++;
Break Find the same word as before and end this comparison
}

}

if (j = = Newword. Count)//does not have the same word as the previous
{
Newword. ADD (Word[i]);
Count. ADD (1);
}

}

Console.WriteLine ("Statistical results: This article has a total of" + Newword. Count + "Different words (detailed statistics are shown in the table below)");

for (int t = 0; t < Newword. Count; t++)
