ASP.NET C# System.IO를 사용하여 하위 디렉터리가있는 디렉터리 복사

Question

전체 디렉터리 C : \ X를 C : \ Y \ X에 복사해야하며 하위 폴더도 복사해야합니다.
System.IO.File \ Directory 네임 스페이스로이를 수행 할 수있는 방법이 있습니까?
모든 도우미에게 감사드립니다.

Answer 1

이 클래스는 재귀 호출없이 폴더를 복사하거나 이동할 것입니다.
메서드는 자체 스택을 사용하여 재귀를 처리합니다.이 방법은 StackOverflowException을 피하는 것입니다.

public static class CopyFolder 
{ 
    public static void CopyDirectory(string source, string target) 
    { 
     var stack = new Stack<Folders>(); 
     stack.Push(new Folders(source, target)); 

     while (stack.Count > 0) 
     { 
      var folders = stack.Pop(); 
      Directory.CreateDirectory(folders.Target); 
      foreach (var file in Directory.GetFiles(folders.Source, "*.*")) 
      { 
       string targetFile = Path.Combine(folders.Target, Path.GetFileName(file)); 
       if (File.Exists(targetFile)) File.Delete(targetFile); 
       File.Copy(file, targetFile); 
      } 

      foreach (var folder in Directory.GetDirectories(folders.Source)) 
      { 
       stack.Push(new Folders(folder, Path.Combine(folders.Target, Path.GetFileName(folder)))); 
      } 
     } 
    } 
    public static void MoveDirectory(string source, string target) 
    { 
     var stack = new Stack<Folders>(); 
     stack.Push(new Folders(source, target)); 

     while (stack.Count > 0) 
     { 
      var folders = stack.Pop(); 
      Directory.CreateDirectory(folders.Target); 
      foreach (var file in Directory.GetFiles(folders.Source, "*.*")) 
      { 
       string targetFile = Path.Combine(folders.Target, Path.GetFileName(file)); 
       if (File.Exists(targetFile)) File.Delete(targetFile); 
       File.Move(file, targetFile); 
      } 

      foreach (var folder in Directory.GetDirectories(folders.Source)) 
      { 
       stack.Push(new Folders(folder, Path.Combine(folders.Target, Path.GetFileName(folder)))); 
      } 
     } 
     Directory.Delete(source, true); 
    } 
    public class Folders 
    { 
     public string Source { get; private set; } 
     public string Target { get; private set; } 

     public Folders(string source, string target) 
     { 
      Source = source; 
      Target = target; 
     } 
    } 
}

이것은 xneurons blog에서 복사됩니다.

public static void CopyAll(DirectoryInfo source, DirectoryInfo target) { 
    // Check if the target directory exists, if not, create it. 
    if (Directory.Exists(target.FullName) == false) { 
     Directory.CreateDirectory(target.FullName); 
    } 

    // Copy each file into it’s new directory. 
    foreach (FileInfo fi in source.GetFiles()) { 
     Console.WriteLine(@"Copying {0}\{1}", target.FullName, fi.Name); 
     fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true); 
    } 

    // Copy each subdirectory using recursion. 
    foreach (DirectoryInfo diSourceSubDir in source.GetDirectories()) { 
     DirectoryInfo nextTargetSubDir = 
      target.CreateSubdirectory(diSourceSubDir.Name); 
     CopyAll(diSourceSubDir, nextTargetSubDir); 
    } 
}

당신은 ... 당신이 복사하기 전에 그냥 디렉토리를 생성 할 필요가 재귀 적 폴더를 검색 할 SearchOption.AllDirectories을 사용할 수 있습니다

// string source, destination; - folder paths 
int pathLen = source.Length; 

foreach (string dirPath in Directory.GetDirectories(source, "*", SearchOption.AllDirectories)) 
{ 
    string subPath = dirPath.SubString(pathLen); 
    string newpath = Path.Combine(destination, subPath); 
    Directory.CreateDirectory(newpath); 
} 

foreach (string filePath in Directory.GetFiles(source, "*.*", SearchOption.AllDirectories)) 
{ 
    string subPath = filePath.SubString(pathLen); 
    string newpath = Path.Combine(destination, subPath); 
    File.Copy(filePath, newpath); 
}
