How to copy sub-folders?

Using the search i've had no problems figuring out how to copy the contents of a folder from one place to another.

But what about copying sub-folders? I'd like to also copy all the sub-folders. Take a look at this:

VB Code:

'Using this import: Imports System.IO
 
'Locate where the program is
Dim sAppPath As String = System.Environment.CurrentDirectory
'Use the test directory with sample files in it
Dim xSourceFolder As New DirectoryInfo(sAppPath & "\test")
Dim xDestinationFolder As New DirectoryInfo(sAppPath & "\test2")
 
'Removes previous instance of the folder and any sub-directories, then creates it fresh
If xDestinationFolder.Exists = True Then xDestinationFolder.Delete(True)
xDestinationFolder.Create()
 
'Copies each file from the source foldr into the destination folder
Dim xFile As FileInfo
For Each xFile In xSourceFolder.GetFiles
     xFile.CopyTo(xDestinationFolder.FullName & "\" & xFile.Name)
Next xFile
Beep()

What if there are a few sub-folders in the "test" folder? How can i copy them and all their contents? I know i'll need a recursive loop, but how do i identify the folder?

according to this link , there is no recursive directory copy .

Did you try something like this :

VB Code:

Dim folds As IO.DirectoryInfo
folds.GetDirectories()

Between those two items, i think i now have enough to build it myself. Thanks Pirate. ;)

I'll let you know what i get when it's all done. :)

Works like a charm. :D Thanks again.

Glad to hear it is working !:)

If you were in C# you could simply do -

Code:

---

using System.IO;

Directory.Move();

---

:D

A possible solution. But i'm a VB.NET guy myself. And i don't want to move the folder; just make a copy of it.

Sorry, still learning .NET like us all. It appears, whether VB or C#, to COPY a directory we will all have to work a little harder.

Here is a small utility class I just wrote that will copy a directory and its contents. The last parameter of the Copy() method specifys if a shallow copy (excluding subdirectories) or deep copy is performed.

Code:

---

using System;
using System.IO;

public class Folder {

    public static void Copy(string target, string destination, bool deep) {
        // verify the source directory exists. also, make sure the destination directory
        // does not already exist. if any of the conditions fail, throw io exception               
        if(Directory.Exists(target)) {
            if(!Directory.Exists(destination)){
                Directory.CreateDirectory(destination);
                ProcessDirectory(target, destination, deep);
            }else {
                throw new IOException("Destination directory already exists");
            }
        }else {
            throw new DirectoryNotFoundException("Directory does not exist");
        }
    }

    private static void ProcessDirectory(string target, string destination, bool deep) {
        // remove trailing backslashes from directory path variables
        target = (target.EndsWith(@"\") ? target.Substring(0, target.Length - 1) : target);
        destination = (destination.EndsWith(@"\") ? destination.Substring(0, destination.Length - 1) : destination);
        // create the new destination directory
        DirectoryInfo current = new DirectoryInfo(target);
        string directoryPath = String.Concat(destination, @"\", current.Name);               
        Directory.CreateDirectory(directoryPath);
        // copy all files within the directory to the new directory
        string[] fileEntries = Directory.GetFiles(target);
        foreach(string fileName in fileEntries) {
            CopyFile(fileName, directoryPath);
        }
        if(deep) {
            // recursively call method for each subdirectory
            string [] subdirectoryEntries = Directory.GetDirectories(target);
            foreach(string subdirectory in subdirectoryEntries) {
                ProcessDirectory(subdirectory, directoryPath, true);
              }
        }
    }

    private static void CopyFile(string source, string destination) {
        // if the source file exists, copy to the new destination
        if(File.Exists(source)) {
            FileInfo sourceFile = new FileInfo(source);
            sourceFile.CopyTo(String.Concat(destination, @"\", sourceFile.Name));
        }
    }

    static void Main() {
        Folder.Copy(@"c:\sonysys", @"d:\copy\", true);       
    }
}

Hi together!

Might be a dumb idea, but why not use the dos command?

Write it into a batch and shell() it?

ok, you might have problems getting back a feedback, but for me it worked fine. rude, not professional, but worked!

Anything i missed? Being a Real VB beginner!!!!!

Example:

' create a string, that is using the dos command move "source" "Target" with " for enabling blanks in pathnames
retvalue = "move " + Chr(34) + source + Chr(34) + " " + Chr(34) + target2 + Chr(34)

' create a bachfile, write the doscommand in there
Open "batchfile.bat" For Output As #2 'save file
Write #2, retvalue
Close #2

' execute the batchfile
obj = Shell("batchfile.bat", vbHide)

' and delete it
Kill "batchfile.bat"

Yes you miss quite a lot. :) You might be in the wrong forum. BTW, you might wanna start learning VB.NET since you are a beginner.

except that the coding not being vb.net,

does the method not work? write a textfile with a doscommand and execute it with a shell?

Not possible in VB.NET?

Mainly was not to have the ideal sollution for VB.NET, was to show the way, I used!

:confused:

Writing DOS Command in a patch-like file is not the ideal solution , although it can be run in .NET app .
