我想将文件夹及其所有子文件夹和文件从一个位置复制到 .NET 中的另一个位置。做到这一点的最佳方法是什么？
I see the Copy method on the System.IO.File class, but was wondering whether there was an easier, better, or faster way than to crawl the directory tree.
我在 System.IO.File 类上看到了 Copy 方法，但想知道是否有比爬行目录树更简单、更好或更快的方法。

Well, there's the VisualBasic.dll implementation that Steve references, and here's something that I've used.
嗯，有 Steve 引用的 VisualBasic.dll 实现，这里有一些我使用过的东西。
private static void CopyDirectory(string sourcePath, string destPath)
{
if (!Directory.Exists(destPath))
{
Directory.CreateDirectory(destPath);
}
foreach (string file in Directory.GetFiles(sourcePath))
{
string dest = Path.Combine(destPath, Path.GetFileName(file));
File.Copy(file, dest);
}
foreach (string folder in Directory.GetDirectories(sourcePath))
{
string dest = Path.Combine(destPath, Path.GetFileName(folder));
CopyDirectory(folder, dest);
}
}

Michal Talaga references the following in his post:
Michal Talaga 在他的帖子中引用了以下内容：
- Microsoft's explanation about why there shouldn't be a Directory.Copy() operation in .NET.
- An implementation of CopyDirectory() from the Microsoft.VisualBasic.dll assembly.
- Microsoft 关于为什么在 .NET 中不应该有 Directory.Copy() 操作的解释。
- Microsoft.VisualBasic.dll 程序集中的 CopyDirectory() 实现。
However, a recursive implementation based on File.Copy()and Directory.CreateDirectory()should suffice for the most basic of needs.
但是，基于File.Copy()并且Directory.CreateDirectory()应该满足最基本需求的递归实现。

If you don't get anything better... perhaps use Process.Startto fire up robocopy.exe?
如果你没有得到更好的东西......也许Process.Start用来激发robocopy.exe？
