C# 将目录复制到其他驱动器

如何将目录复制到C#中的其他驱动器

位于VB命名空间和程序集中，但这可能无关紧要。

C#递归复制文件夹

---

您可以使用此代码执行操作：

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);
    }
}

下面一个也很好：

    static public 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 );
        }
    }

您还可以使用此功能：

私有字符串路径；
public int-copyAllContents（字符串目标文件夹，ProgressBar ProgressBar）
{
int countCopyFiles=0；
如果（！Directory.Exists（destinationFolder））
{Directory.CreateDirectory（destinationFolder）；}
字符串[]allFilesForCurrentFolder=Directory.GetFiles（路径“**”，SearchOption.TopDirectoryOnly）；
字符串[]子文件夹sallpath=Directory.GetDirectories（path）；
for（int i=0；i

这是一个在.NET 4.0中可用的扩展+

var source = new DirectoryInfo(@"C:\Test");
var destination = new DirectoryInfo(@"E:\Test");
source.CopyTo(destination);

在项目中包含此文件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace System.IO
{
  public static class DirectoryInfoExtensions
  {
    public static void CopyTo(this DirectoryInfo source, DirectoryInfo target)
    {
      if (!target.Exists)
        target.Create();

      foreach (var file in source.GetFiles())
        file.CopyTo(Path.Combine(target.FullName, file.Name), true);

      foreach (var subdir in source.GetDirectories())
        subdir.CopyTo(target.CreateSubdirectory(subdir.Name));
    }
  }
}

下面是一种将目录递归复制为

async

函数的方法：

public static async Task CopyDirectoryAsync(string sourceDirectory, string destinationDirectory)
{
    if (!Directory.Exists(destinationDirectory))
        Directory.CreateDirectory(destinationDirectory);

    foreach (var file in Directory.GetFiles(sourceDirectory))
    {
        var name = Path.GetFileName(file);
        var dest = Path.Combine(destinationDirectory, name);
        await CopyFileAsync(file, dest);
    }

    foreach (var subdir in Directory.GetDirectories(sourceDirectory))
    {
        var name = Path.GetFileName(subdir);
        var dest = Path.Combine(destinationDirectory, name);
        await CopyDirectoryAsync(subdir, dest);
    }
}

public static async Task CopyFileAsync(string sourceFile, string destinationFile)
{
    using (var sourceStream = new FileStream(sourceFile, FileMode.Open, FileAccess.Read, FileShare.Read, 4096, FileOptions.Asynchronous | FileOptions.SequentialScan))
    using (var destinationStream = new FileStream(destinationFile, FileMode.CreateNew, FileAccess.Write, FileShare.None, 4096, FileOptions.Asynchronous | FileOptions.SequentialScan))
        await sourceStream.CopyToAsync(destinationStream);
}

哈哈，什么？抱歉，没有取笑任何人，只是觉得这个问题的提问方式很滑稽：）我知道问题已经得到了回答，但你应该尝试提高问题的质量。这篇文章写得不太好。我想我们需要一个新的结束理由——“如果OP做出努力，很容易找到”我检查了你的“用户详细信息”，发现你是新来的，我不想让你泄气，因为同样的事情也发生在我身上，当我刚加入stackoverflow时，这对程序员来说是一个非常好的社区，你只需首先尝试在谷歌上搜索主题，如果你没有找到他们的解决方案，那么只需把你的问题放在这里，也可以把你为完成这项任务而编写的代码放在这里（如果你有）。如果你的代码格式正确，其他人阅读你的答案会容易得多。此外，最好在代码中添加一些上下文。写下你为什么认为这是一个好答案，或者它与其他答案有什么不同。@Crash893是的。@KyleDelaney是的，现在是了（我发这篇文章已经7年了）@Crash893马修发这篇文章已经7年了。5年前你这么做了。
