根据单词分配一定的分数

谢谢解决了。

我的words.txt文件如下所示： 

await   -1
awaited -1
award   3
awards  3

这些值以制表符分隔。首先，我想得到结果，例如，await = -1 分，并根据words.txt文件为我的评论.txt文件中的每一句话提供分数。程序的输出应该像(例如(

-1.0
2.0
0.0
5.0

我被困住了，不知道下一步应该做什么。到目前为止，我只设法阅读了words.txt文件。

    const char DELIM = ''t'; 
    const string FILENAME = @"words.txt"; 
    string record;  
    string[] fields; 
    FileStream inFile; 
    StreamReader reader; 

    inFile = new FileStream(FILENAME, FileMode.Open, FileAccess.Read);
    reader = new StreamReader(inFile);
    record = reader.ReadLine();
    //Spliting up a string using delimiter and
    //storing the spilt strings into a string array
    fields = record.Split(DELIM);
    double values = double.Parse(fields[1]);
    string words = fields[0];

根据单词分配一定的分数

如果你想使用正则表达式方法，试试这个

using (FileStream fileStream = new FileStream(FILENAME, FileMode.Open, FileAccess.Read)) {
  using (StreamReader streamReader = new StreamReader(fileStream)) {
    String record = streamReader.ReadLine();
    foreach (String str in record.Split(''t')) {
      Console.WriteLine(Regex.Replace(str, @"[^-?'d+]", String.Empty));
    }
    streamReader.Close();
  }
  fileStream.Close();
}

用文字测试.txt

await -1    awaited -1  awaited -1  award 3 award 2 award 1 award 3 awards 3

你应该看看字典，你可以将你想要打分的每个单词与他在字典中的值相匹配。通过这种方式，您可以循环获得的所有单词并输出值

using System;
using System.Collections.Generic;
class Program
{
    static void Main()
    {
        Dictionary<string, int> dictionary = new Dictionary<string, int>();
        dictionary.Add("await", -1);
        dictionary.Add("awaited", -1);
        dictionary.Add("award", 3);
        dictionary.Add("awards", 3);
        //read your file
        //split content on the splitter (tab) in an array
        for(int i=0; i<array.Length; i++)
        {
            //output the value
        }
    }
}

结合 vadz 的答案和 im_a_noob 的答案，您应该能够阅读您的单词.txt文件并将其放入字典中。

    Dictionary<string, double> wordDictionary = new Dictionary<string, double>();
    using (FileStream fileStream = new FileStream(FILENAME, FileMode.Open, FileAccess.Read))
        {
            using (StreamReader reader = new StreamReader(fileStream))
            {
                int lineCount = 0;
                int skippedLine = 0;
                while( !reader.EndOfStream)
                {
                    string[] fields = reader.ReadLine().Split(''t');
                    string word = fields[0];
                    double value = 0;
                    lineCount++;
                    //this check verifies there are two elements, tries to parse the second value and checks that the word 
                    //is not already in the dictionary
                    if (fields.Count() == 2 && double.TryParse(fields[1], out value) && !wordDictionary.ContainsKey(word))
                    {
                        wordDictionary.Add(word, value);
                    }
                    else{
                        skippedLine++;
                    }
                }
                Console.WriteLine(string.Format("Total Lines Read: {0}", lineCount));
                Console.WriteLine(string.Format("Lines Skipped: {0}", skippedLine));
                Console.WriteLine(string.Format("Expected Entries in Dictonary: {0}", lineCount - skippedLine));
                Console.WriteLine(string.Format("Actual Entries in Dictionary: {0}", wordDictionary.Count()));
                reader.Close();
            }
            fileStream.Close();
        }

要对句子进行评分，您可以使用如下所示的内容。

    string fileText = File.ReadAllText(COMMENTSTEXT); //COMMENTSTEXT = comments.txt
    // assumes sentences end with a period, won't take into account any other periods in sentence
    var sentences = fileText.Split('.'); 
    foreach( string sentence in sentences )
    {
        double sentenceScore = 0;
        foreach (KeyValuePair<string, double> word in wordDictionary)
        {
            sentenceScore += sentence.Split(' ').Count(w => w == word.Key) * word.Value; 
        }
        Console.WriteLine(string.Format("Sentence Score = {0}", sentenceScore));
    }

没有字典的工作解决方案：

using System.IO;
using System.Text.RegularExpressions; 
class Program
{
    static void Main(string[] args)
    {
        foreach (var comment in File.ReadAllLines(@"..'..'comments.txt"))
            Console.WriteLine(GetRating(comment));
        Console.ReadLine();
    }
    static double GetRating(string comment)
    {
        double rating = double.NaN;
        var wordsLines = from line in File.ReadAllLines(@"..'..'words.txt")
                         where !String.IsNullOrEmpty(line)
                         select Regex.Replace(line, @"'s+", " ");
        var wordRatings = from wLine in wordsLines
                          select new { Word = wLine.Split()[0],  Rating = Double.Parse(wLine.Split()[1]) };

        foreach (var wr in wordRatings)
        {
            if (comment.ToLower().Split(new Char[] {' ', ',', '.', ':', ';'}).Contains(wr.Word))
                rating = wr.Rating;
        }
        return rating;
    }
}
