问题
My source path is C:\Music\ in which I have hundreds of folders called Album-1, Album-2 etc.
What I want to do is create a folder called Consolidated in my source path.
And then I want to move all the files inside my albums to the folder Consolidated, so that I get all the music files in one folder.
How can I do this ?
回答1:
Try like this
String directoryName = "C:\\Consolidated";
DirectoryInfo dirInfo = new DirectoryInfo(directoryName);
if (dirInfo.Exists == false)
Directory.CreateDirectory(directoryName);
List<String> MyMusicFiles = Directory
.GetFiles("C:\\Music", "*.*", SearchOption.AllDirectories).ToList();
foreach (string file in MyMusicFiles)
{
FileInfo mFile = new FileInfo(file);
// to remove name collisions
if (new FileInfo(dirInfo + "\\" + mFile.Name).Exists == false)
{
mFile.MoveTo(dirInfo + "\\" + mFile.Name);
}
}
It will get all the files in the "C:\Music" folder (including files in the subfolder) and move them to the destination folder. The SearchOption.AllDirectories will recursively search all the subfolders.

You can use the Directory object to do this, but you might run into problems if you have the same file name in multiple sub directories (e.g. album1\1.mp3, album2\1.mp3) so you might need a little extra logic to tack something unique onto the names (e.g. album1-1.mp4).
public void CopyDir( string sourceFolder, string destFolder )
{
if (!Directory.Exists( destFolder ))
Directory.CreateDirectory( destFolder );
// Get Files & Copy
string[] files = Directory.GetFiles( sourceFolder );
foreach (string file in files)
{
string name = Path.GetFileName( file );
// ADD Unique File Name Check to Below!!!!
string dest = Path.Combine( destFolder, name );
File.Copy( file, dest );
}
// Get dirs recursively and copy files
string[] folders = Directory.GetDirectories( sourceFolder );
foreach (string folder in folders)
{
string name = Path.GetFileName( folder );
string dest = Path.Combine( destFolder, name );
CopyDir( folder, dest );
}
}

Basically, that can be done with Directory.Move:
try
{
Directory.Move(source, destination);
}
catch { }
don't see any reason, why you shouldn't use this function. It's recursive and speed optimized

public void MoveDirectory(string[] source, string target)
{
var stack = new Stack<Folders>();
stack.Push(new Folders(source[0], target));
while (stack.Count > 0)
{
var folders = stack.Pop();
Directory.CreateDirectory(folders.Target);
foreach (var file in Directory.GetFiles(folders.Source, "*.*"))
{
string targetFile = Path.Combine(folders.Target, Path.GetFileName(file));
if (File.Exists(targetFile)) File.Delete(targetFile); File.Move(file, targetFile);
}
foreach (var folder in Directory.GetDirectories(folders.Source))
{
stack.Push(new Folders(folder, Path.Combine(folders.Target, Path.GetFileName(folder))));
}
}
Directory.Delete(source[0], true);
}
}
public class Folders {
public string Source {
get; private set;
}
public string Target {
get; private set;
}
public Folders(string source, string target) {
Source = source;
Target = target;
}
}

Something like this should get you rolling. You'll have to add error checking and what not (What if there is a subdirectory of source named "Consolidated"? What if Consolidated already exists? Etc.) This is from memory, so pardon any syntax errors, etc.
string source = @"C:\Music";
string[] directories = Directory.GetDirectories(source);
string consolidated = Path.Combine(source, "Consolidated")
Directory.CreateDirectory(consolidated);
foreach(var directory in directories) {
Directory.Move(directory, consolidated);
}

You'll probably find this helpful to dedup your mp3's that have a different file name but same title.
source from David @ msdn!
byte[] b = new byte[128];
string sTitle;
string sSinger;
string sAlbum;
string sYear;
string sComm;
FileStream fs = new FileStream(file, FileMode.Open);
fs.Seek(-128, SeekOrigin.End);
fs.Read(b, 0, 128);
bool isSet = false;
String sFlag = System.Text.Encoding.Default.GetString(b, 0, 3);
if (sFlag.CompareTo("TAG") == 0)
{
System.Console.WriteLine("Tag is setted! ");
isSet = true;
}
if (isSet)
{
//get title of song;

回答9:
You loop through them and then simply run Move, the Directory class have functionality for listing contents too iirc.
回答10:
You might be interested in trying Powershell and/or Robocopy to do this task. It'll be a lot more concise than creating a C# application for the task. Powershell is also a great tool for your development tool-belt.
I believe Powershell and Robocopy are both installed by default on Windows Vista and 7.
This might be a good place to start: http://technet.microsoft.com/en-us/library/ee332545.aspx
