Copying Files Recursively
Solution 1
instead of
foreach (string file in Directory.GetFiles(baseDir, "*.*", SearchOption.AllDirectories))
{
do something like this
foreach (FileInfo fi in source.GetFiles())
{
fi.CopyTo(Path.Combine(target.ToString(), fi.Name), true);
}
Solution 2
MSDN has a complete sample: How to: copy directories
using System;
using System.IO;
class DirectoryCopyExample
{
static void Main()
{
// Copy from the current directory, include subdirectories.
DirectoryCopy(".", @".\temp", true);
}
private static void DirectoryCopy(string sourceDirName, string destDirName,
bool copySubDirs)
{
// Get the subdirectories for the specified directory.
DirectoryInfo dir = new DirectoryInfo(sourceDirName);
if (!dir.Exists)
{
throw new DirectoryNotFoundException(
"Source directory does not exist or could not be found: "
+ sourceDirName);
}
DirectoryInfo[] dirs = dir.GetDirectories();
// If the destination directory doesn't exist, create it.
if (!Directory.Exists(destDirName))
{
Directory.CreateDirectory(destDirName);
}
// Get the files in the directory and copy them to the new location.
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)
{
string temppath = Path.Combine(destDirName, file.Name);
file.CopyTo(temppath, false);
}
// If copying subdirectories, copy them and their contents to new location.
if (copySubDirs)
{
foreach (DirectoryInfo subdir in dirs)
{
string temppath = Path.Combine(destDirName, subdir.Name);
DirectoryCopy(subdir.FullName, temppath, copySubDirs);
}
}
}
}

No, wait, actually it's much better, because of the wide skillset and quantity of geeks.

I found a small snippet for doing a recursive file copy in C#, but am somewhat stumped. I basically need to copy a directory structure to another location, along the lines of this...
Source: C:\data\servers\mc
Target: E:\mc
The code for my copy function as of right now is...
//Now Create all of the directories foreach (string dirPath in Directory.GetDirectories(baseDir, "*", SearchOption.AllDirectories)) { Directory.CreateDirectory(dirPath.Replace(baseDir, targetDir)); } // Copy each file into it’s new directory. foreach (string file in Directory.GetFiles(baseDir, "*.*", SearchOption.AllDirectories)) { Console.WriteLine(@"Copying {0}\{1}", targetDir, Path.GetFileName(file)); if (!CopyFile(file, Path.Combine(targetDir, Path.GetFileName(file)), false)) { int err = Marshal.GetLastWin32Error(); Console.WriteLine("[ERROR] CopyFile Failed on {0} with code {1}", file, err); } }
The issue is that in the second scope, I either:
- use
Path.GetFileName(file)
to get the actual file name without the path but I lose the directory "mc" directory structure or - use "file" without Path.Combine.
Either way I have to do some nasty string work. Is there a good way to do this in C# (my lack of knowledge with the .NET API leads me to over complicating things)

Mikhail Zhuravlev over 6 yearssource.GetFiles() won't recursively get files in subdirectories, but only in the "source" directory.
