在C＃中递归复制内容的最佳方法是什么？

使用C＃和ASP.NET以递归方式将文件夹的内容复制到另一个文件夹的最佳方法是什么？

Answer 1

那么你可以试试这个

DirectoryInfo sourcedinfo = new DirectoryInfo(@"E:\source"); DirectoryInfo destinfo = new DirectoryInfo(@"E:\destination"); copy.CopyAll(sourcedinfo, destinfo); 

这是完成所有工作的方法：

 public void CopyAll(DirectoryInfo source, DirectoryInfo target) { try { //check if the target directory exists if (Directory.Exists(target.FullName) == false) { Directory.CreateDirectory(target.FullName); } //copy all the files into the new directory foreach (FileInfo fi in source.GetFiles()) { fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true); } //copy all the sub directories using recursion foreach (DirectoryInfo diSourceDir in source.GetDirectories()) { DirectoryInfo nextTargetDir = target.CreateSubdirectory(diSourceDir.Name); CopyAll(diSourceDir, nextTargetDir); } //success here } catch (IOException ie) { //handle it here } } 

我希望这个能帮上忙 ：）

Answer 2

只需在Microsoft.VisualBasic.dll程序集中使用Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory 。

添加对Microsoft.VisualBasic的引用

 Microsoft.VisualBasic.FileIO.FileSystem.CopyDirectory(source, destination); 

Answer 3

您可以使用SearchOption.AllDirectories递归搜索文件夹，您只需要在复制之前创建目录…

 // string source, destination; - folder paths int pathLen = source.Length + 1; 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); }
