以下代码已经过严格测试：%%1，%%2请替换为源文件夹和目标源文件夹
13.复制文件夹
//using System.IO;
//using System.Collections;
string path = (%%2.LastIndexOf("\\") == %%2.Length - 1) ? %%2 : %%2+"\\";
string parent = Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path + Path.GetFileName(%%1));
%%1 = (%%1.LastIndexOf("\\") == %%1.Length - 1) ? %%1 : %%1 + "\\";
DirectoryInfo dir = new DirectoryInfo(%%1);
FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count>0)
{
FileSystemInfo tmp = Folders.Dequeue();
FileInfo f = tmp as FileInfo;
if (f == null)
{
DirectoryInfo d = tmp as DirectoryInfo;
Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf("\\") == parent.Length - 1) ? parent : parent + "\\", path));
foreach (FileSystemInfo fi in d.GetFileSystemInfos())
{
Folders.Enqueue(fi);
}
}
else
{
f.CopyTo(f.FullName.Replace(parent, path));
}
}

15.移动文件夹
//using System.IO;
//using System.Collections;
string filename = Path.GetFileName(%%1);
string path=(%%2.LastIndexOf("\\") == %%2.Length - 1) ? %%2 : %%2 + "\\";
if (Path.GetPathRoot(%%1) == Path.GetPathRoot(%%2))
Directory.Move(%%1, path + filename);
else
{
string parent = Path.GetDirectoryName(%%1);
Directory.CreateDirectory(path + Path.GetFileName(%%1));
%%1 = (%%1.LastIndexOf("\\") == %%1.Length - 1) ? %%1 : %%1 + "\\";
DirectoryInfo dir = new DirectoryInfo(%%1);
FileSystemInfo[] fileArr = dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders = new Queue<FileSystemInfo>(dir.GetFileSystemInfos());
while (Folders.Count > 0)
{
FileSystemInfo tmp = Folders.Dequeue();
FileInfo f = tmp as FileInfo;
if (f == null)
{
DirectoryInfo d = tmp as DirectoryInfo;
DirectoryInfo dpath = new DirectoryInfo(d.FullName.Replace((parent.LastIndexOf("\\") == parent.Length - 1) ? parent : parent + "\\", path));
dpath.Create();
foreach (FileSystemInfo fi in d.GetFileSystemInfos())
{
Folders.Enqueue(fi);
}
}
else
{
f.MoveTo(f.FullName.Replace(parent, path));
}
}
Directory.Delete(%%1, true);
}
