c# - 复制包含所有文件和文件夹的目录

Question

我正在尝试将一个目录复制到另一个路径。
我找到了这个方法，但是它不复制目录，只复制其中的子目录和文件:

string sourcedirectory = Environment.ExpandEnvironmentVariables("%AppData%\\Program");

foreach (string dirPath in Directory.GetDirectories(sourcedirectory, "*", SearchOption.AllDirectories))
{
    Directory.CreateDirectory(dirPath.Replace(sourcedirectory, folderDialog.SelectedPath));
}
foreach (string newPath in Directory.GetFiles(sourcedirectory, "*.*", SearchOption.AllDirectories))
{
    File.Copy(newPath, newPath.Replace(sourcedirectory, folderDialog.SelectedPath), true);
}

如何在包含所有文件和子文件夹的输出中获取“Program”文件夹？

Answer 1

如果在开始复制之前调整输出路径，它应该可以工作:

string sourcedirectory = Environment.ExpandEnvironmentVariables("%AppData%\\Program");

folderDialog.SelectedPath = Path.Combine(folderDialog.SelectedPath,
    Path.GetFileName(sourcedirectory));

foreach (string dirPath in Directory.GetDirectories(sourcedirectory, "*", SearchOption.AllDirectories))
{
    Directory.CreateDirectory(dirPath.Replace(sourcedirectory, folderDialog.SelectedPath));
}
foreach (string newPath in Directory.GetFiles(sourcedirectory, "*.*", SearchOption.AllDirectories))
{
    File.Copy(newPath, newPath.Replace(sourcedirectory, folderDialog.SelectedPath), true);
}
