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:
Path.GetFileName(file)
to get the actual file name without the path but I lose the directory "mc" directory structure orEither 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)
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);
}
}
}
}
