將數組代碼轉換爲數組列表C＃

Question

我需要將其作爲數組列表而不是數組，並且我不知道如何啓動。該程序將獲取一個文件並逐行讀取文件，並檢查每個不可識別字符出現的次數。

 class Program 
    { 
    static void Main(string[] args) 
    { 
     // Parse arguments. 
     if (args.Length != 2) 
     { 
      Console.WriteLine("Two arguments are needed."); 
      return; 
     } 
     var inputFile = args[0]; 
     var outputFile = args[1]; 
     var asciiTable = new charfrequency[255]; 
     var input = File.ReadAllLines(inputFile); 
     var output = ""; 

     Console.WriteLine(string.Format("The input file is: <{0}>.", inputFile)); 
     Console.WriteLine(string.Format("The output file is: <{0}>.", outputFile)); 


     // creates the asci table. 
     for (var i = 0; i < asciiTable.Length; i++) 
     { 
      asciiTable[i] = new charfrequency(); 
      asciiTable[i].setCharacter((char)i); 
     } 

     // Parse the file line by line. 
     foreach (var line in input) 
     { 
      foreach (var character in line) 
      { 
       var key = (int)character; 

       if (key < 255 && key >= 0) 
       { 
        asciiTable[key].increment(); 
       } 
      } 
     } 

     // Write to the output string. 
     foreach (var charfrequency in asciiTable) 
     { 
      if (charfrequency.getFrequency() > 0) 
      { 
       output += charfrequency.toString(); 
       //string.Format("{0}[{1}]: {2}{3}", charfrequency.getCharacter(),   (int)charfrequency.getCharacter(), charfrequency.getFrequency(), Environment.NewLine); 
      } 
     } 

     // Write the output string to the outputFile. 
     File.WriteAllText(outputFile, output); 
    }

如果您使用LINQ命令，這可能會更容易。 Here是一篇文章，解釋瞭如何在文件中使用LINQ。這不是完整的答案，但它可能會讓你更接近它。
