在C＃中將文本文件讀入數組中

Question

這是需要處理的文本文件的摘錄。需要完成的是程序 必須在這個文本文件中讀取並將其格式化爲一個規範。問題是我沒有太多的工作 與文本文件的體驗。這是示例輸入文件。

當處理的輸出文件應如下所示：

BTAK000, AISHA KEJO, NLCB_R6.0_ACCESSCTRL 
BTAK000, AISHA KEJO, NLCB_R6.0_VERAUT_MBE 

正如你所看到的，所需要的一切數據，但只有運營商ID，姓名和活動的配置文件需要輸出被拉。 如果在文件中找到每個操作員標識，則結果需要打印到新行。如果用戶有超過1 活動配置文件，則必須將操作員標識和名稱和配置文件輸出到新行。如果用戶具有禁用的配置文件 ，則必須忽略數據。正如您從示例中所看到的，第一個單元被忽略，因爲它們被禁用。具有啓用satatus的 用戶就是例子。正如你可以看到的輸出示例。

我的想法是將數據拉到數組中，但只輸出操作員ID，名稱和配置文件。我該怎麼做呢？

這是我到目前爲止有：

Console.WriteLine("Enter Input File Location: " + "\n"); 

      //Reads path specifed by the user for input. 
      string t = File.ReadAllText(Console.ReadLine()); 

      //Splits file where there is an equals sign. 
      t = t.Replace("=", ""); 
      //Removes all tabbed spaces. 
      t = t.Replace("\t", ""); 
      //Removes any new lines. 
      t = t.Replace("\n", ","); 
      //Removes blank spaces. 
      t = t.Replace(" ", ""); 
      //Removes the Underscore. 
      t = t.Replace("_", ""); 

      //Removes any leading or trailing whitespaces. 
      t = t.Trim(','); 

      //Writes formatted file to a pre defined ouput file's location. 
      File.WriteAllText(@"C:/3rd Quarter1.txt", t); 

Answer 1

隨着您可以通過調用的TextReader的ReadLine方法讀取每一行一個TextReader的。

你在一段時間（！textreader.EndOfFile）

對於每一行，您可以搜索特定的字符做到這一點 - >搜索=和用它做後面的文本的東西。

您還可以檢查是否符合運營商ID

Answer 2

開始，你可以使用正則表達式來查找你的整個文件加載到流尋找..

開始的東西。 再使用這樣的正則表達式：

@"Operator ID = (.+?) Name = (.+?) Active profile = (.+?) Enable status " 

會發現所有的職位，那麼你OFC需要做陣列另一個正則表達式檢查，以提取activeProfiles（並查看是否有多於1）

是這樣的：

@"Active profile = (.+?) " 

disclamer ..你可能需要修改的正則表達式來適應一下StreamReader的其實是把到流。

Here是一個很好的工具來檢查你的reqex的

編輯：這是方案如何能看起來像一個示例：

static void Main(string[] args) 
    { 
     string path = @"c:\test.txt"; 
     string t = File.ReadAllText(path); 
     string pattern1 = @"OperatorID=(.+?),,Name=(.+?),(.+?),Enablestatus"; 
     Regex rgx = new Regex(pattern1); 

     //Removes all tabbed spaces. 
     t = t.Replace("\t", ""); 
     //Removes any new lines. 
     t = t.Replace("\n", ","); 
     //Removes blank spaces. 
     t = t.Replace(" ", ""); 
     //Removes the Underscore. 
     t = t.Replace("_", ""); 
     t = t.Replace("\r", ""); 

     MatchCollection matches = rgx.Matches(t); 
     List<string[]> test = new List<string[]>(); 
     foreach (var match in matches) 
     { 
      string[] newString = match.ToString().Split(new string[] { @"OperatorID=", @",,Name=", @",Activeprofile=", @",Enablestatus", }, StringSplitOptions.RemoveEmptyEntries); 

      for (int i = 3 ; i <= newString.Length; i++) 
      { 
       test.Add(new string[] { newString[0], newString[1], newString[i - 1] }); 
      } 

     } 

     foreach (var line in test) 
     { 
      Console.WriteLine("ID: {0}\nName: {1}\nActive Profile: {2}\n", line[0], line[1], line[2]); 
     } 

     Console.ReadKey(); 

沒有給予很多的關注細節，這壽:)

編輯：要將結果添加到文件：

 using (StreamWriter myWriter = new StreamWriter(@"c:\testOutput.txt")) 
    { 

     foreach (var line in test) 
     { 
      myWriter.WriteLine("ID: {0}", line[0]); 
      myWriter.WriteLine("Name: {0}", line[1]); 
      myWriter.WriteLine("Active Profile: {0}", line[2]); 
      myWriter.WriteLine(); 


     } 
    }
