在C＃中将文本文件读入数组中

Question

这是需要处理的文本文件的摘录。需要完成的是程序 必须在这个文本文件中读取并将其格式化为一个规范。问题是我没有太多的工作 与文本文件的体验。这是示例输入文件。

BSA  Security Definition - Operator Report Type 28

Calculated pwd  = 4B    
One-time password  = No    
Assigned unit   = None    

当处理的输出文件应如下所示：

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

正如你所看到的，所需要的一切数据，但只有运营商ID，姓名和活动的配置文件需要输出被拉。 如果在文件中找到每个操作员标识，则结果需要打印到新行。如果用户有超过1 活动配置文件，则必须将操作员标识和名称和配置文件输出到新行。如果用户具有禁用的配置文件 ，则必须忽略数据。正如您从示例中所看到的，第一个单元被忽略，因为它们被禁用。具有启用satatus的 用户就是例子。正如你可以看到的输出示例。

我的想法是将数据拉到数组中，但只输出操作员ID，名称和配置文件。我该怎么做呢？

这是我到目前为止有：

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

随着您可以通过调用的TextReader的ReadLine方法读取每一行一个TextReader的。

你在一段时间（！textreader.EndOfFile）

对于每一行，您可以搜索特定的字符做到这一点 - >搜索=和用它做后面的文本的东西。

您还可以检查是否符合运营商ID

Answer 2

开始，你可以使用正则表达式来查找你的整个文件加载到流寻找..

开始的东西。 再使用这样的正则表达式：

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

会发现所有的职位，那么你OFC需要做阵列另一个正则表达式检查，以提取activeProfiles（并查看是否有多于1）

是这样的：

@"Active profile = (.+?) " 

disclamer ..你可能需要修改的正则表达式来适应一下StreamReader的其实是把到流。

Here是一个很好的工具来检查你的reqex的

编辑：这是方案如何能看起来像一个示例：

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(); 

没有给予很多的关注细节，这寿:)

编辑：要将结果添加到文件：

 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(); 


     } 
    }
