C＃如果文件名的一部分與文件夾名稱匹配，將文件移動到文件夾中

Question

如果.CID文件名的一部分與目錄名的一部分相匹配，我想將其移動到目錄中。

下面是一些示例目錄：

S002016-P063 // projectnumber-panelnumber 
S002016-P066 
S002016-P067 

下面是一些示例文件名：

P063-1.LEFT.CID // move to S002016-P063 directory 
P063-10.RIGHT.CID // move to S002016-P063 directory 
P066-2_P066-5.LEFT.CID // move to S002016-P066 because P066 == P066 
P067-12.LEFT.CID // move to S002016-P067 
P067-5_P063-2.RIGHT.CID // leave file where it’s at because P067 != P063 

現在我身體這些文件移動到相應的目錄，但我以爲這是可以做到用控制檯應用程序。我想知道如果我需要設置一些if語句使用正則表達式類，也許匹配方法？我是C＃的新手，想要一些幫助入門。這是我到目前爲止。基本上，控制檯應用程序將列出指定目錄中的目錄和文件。

class Program 
{ 
    static void Main(string[] args) 
    { 
     Console.WriteLine("Hello and Welcome to the File Sorting Program"); // Displays Text in Quotes 

     Console.WriteLine(); // Adds a Space 

     string[] fileEntries = Directory.GetDirectories(@"\\Users\none\Documents\File Sorter"); // Regex for panel number = -([A-Z0-9a-z\-]+) 

     System.Console.WriteLine("Directories in the Folder: "); 

     Console.WriteLine(); // Adds a Space 

     foreach (string fileName in fileEntries) 
     { 
      Console.WriteLine(Path.GetFileName(fileName)); // Lists the directories found in the "File Sorter" directory 
     } 

     Console.WriteLine(); // Adds a Space 
     Console.WriteLine(); // Adds a Space 

     string[] files = Directory.GetFiles(@"\\Users\none\Documents\File Sorter", "*.CID"); // Regex for panel number = ([A-Z0-9a-z\-]+)- 

     System.Console.WriteLine("Files in this Folder: "); // Displays Text in Quotes 

     Console.WriteLine(); // Adds a Space 

     foreach (string file in files) 
     { 
      Console.WriteLine(System.IO.Path.GetFileNameWithoutExtension(file)); // Lists each file minus .CID found in the "File Sorter" directory 
     } 

     Console.WriteLine("Press any key to exit."); // Displays Text in Quotes 

     System.Console.ReadKey();  
    } 
}

假設你的文件夾名和文件名模式是一致的，這應該大約給你你要找的東西：

string root = @"\\Users\none\Documents\File Sorter"; 

string[] directories = Directory.GetDirectories(root); 
var dirRef = directories.ToDictionary(k => k.Split('-')[1], v => v); 

string[] files = Directory.GetFiles(root); 
foreach (var file in files) 
{ 
    string fileName = Path.GetFileName(file); 
    string projectName = null; 
    foreach (Match m in Regex.Matches(fileName, "[A-Za-z0-9]+(?=-)")) 
    { 
     if (projectName == null) 
     { 
      projectName = m.Value; 
     } 
     else if (projectName != m.Value) 
     { 
      projectName = null; 
      break; 
     } 
    } 

    if (projectName == null) 
    { 
     Console.WriteLine("Project names in file {0} do not match.", fileName); 
    } 
    else if (dirRef.ContainsKey(projectName)) 
    { 
     File.Move(file, dirRef[projectName] + "\\" + fileName); 
     Console.WriteLine("File {0} moved to directory {1}.", fileName, dirRef[projectName]); 
    } 
    else 
    { 
     Console.WriteLine("Directory with project name {0} doesn't exist", projectName); 
    } 
}

我做了一些測試，這個片段處理所有的以上情況使用了一些Regex。顯然它可以改善，但它是你的工作起點:)

var projectFolders = Directory.GetDirectories(@"Projects/"); 
var fileEligibleToBeMoved = new List<string>(); 

var files = Directory.GetFiles(Directory.GetCurrentDirectory()); 

foreach (var file in files) 
{ 
    if (!file.Contains(".CID")) 
     continue; 
    var fileName = Path.GetFileName(file); 
    var matches = Regex.Matches(fileName, @"(P[a-zA-Z0-9]+)"); 

    if (matches.Count == 0) 
     continue; 

    var isEligible = true; 
    var previous = string.Empty; 
    foreach (Match match in matches) 
    { 
     if(previous == string.Empty) 
     { 
      previous = match.Value; 
      continue; 
     } 
     if (previous != match.Value) 
      isEligible = false; 
    } 
    if (isEligible) 
     fileEligibleToBeMoved.Add(file);     
} 

foreach (var dir in projectFolders) 
{ 
    var panelTag = Regex.Match(dir, @"-\w+").Value.Replace("-", "");     
    var filesToMove = fileEligibleToBeMoved 
     .Where(file => file.Contains(panelTag)) 
     .ToArray(); 
    foreach (var file in filesToMove) 
    { 

     File.Move(file, string.Format("{0}/{1}", dir, Path.GetFileName(file))); 
    } 
}
