如何创建递归函数来复制所有文件和文件夹

Question

我正在尝试创建一个函数,将递归复制源文件夹及其中的所有文件和文件夹到其他位置.

目前,我必须在主文件夹中定义每个文件夹,这使得代码变得臃肿和冗余.

有什么更有效的方法呢？

Answer 1

看看我的问题:

复制目录的性能 我使用并行foreach,它非常快

private static void CopyAll(string SourcePath, string DestinationPath)
{

string[] directories = System.IO.Directory.GetDirectories(SourcePath, "*.*", SearchOption.AllDirectories);

Parallel.ForEach(directories, dirPath =>
{
    Directory.CreateDirectory(dirPath.Replace(SourcePath, DestinationPath));
}); 

string[] files = System.IO.Directory.GetFiles(SourcePath, "*.*", SearchOption.AllDirectories);

Parallel.ForEach(files, newPath =>
{
    File.Copy(newPath, newPath.Replace(SourcePath, DestinationPath));
}); 
}

来源：C# - 在 c-sharp 中将文件和文件夹从源递归复制到目标文件夹

public static void CopyFolder(string sourceFolder, string destFolder)  
{  
    if (!Directory.Exists(destFolder))  
        Directory.CreateDirectory(destFolder); 

    string[] files = Directory.GetFiles(sourceFolder);  
    foreach (string file in files)  
    {  
        string name = Path.GetFileName(file);  
        string dest = Path.Combine(destFolder, name);  
        File.Copy(file, dest);  
    }  
    string[] folders = Directory.GetDirectories(sourceFolder);  
    foreach (string folder in folders)  
    {  
        string name = Path.GetFileName(folder);  
        string dest = Path.Combine(destFolder, name);  
        CopyFolder(folder, dest);  
    }  
}
