Thanks in advance

Answer 1

You will a client installed on the remote computer that is open for communication from the local computer, or via a server that will get the files from the remote. the question is what your system architecture? does both computer in the same LAN? or these are computers over the internet?

Hi,

Thanks for the reply.Both of the computers are on the same LAN. i just need to copy the files and subfolders inside the main folder to my local drive using C#.Net. 

Answer 3

In this case, just map the remote computer as a network folder on the local computer, and do a simple file-system copy (File.Copy(...)).

If you can copy via the file system, File.Copy should work as well. Can you?

i am able to copy it via file system . using run and then typing the ip address of remote server but when doing through asp.net. it is throwing me login failure exception. i know the reason for this. Actually while doing copy through file system, i enter a different user name and password but while doing through .net, it is taking my default login and password which does not have access to that file. So i want to provide that user name and password which has access to the remote folder. can i do it in my program? thanks

Answer 8

can some one please help me with this. i urgently require this code and not able to copy files from remote system. Searched everywhere in msdn but did not  found any solution till yet.

Answer 9

If you are doing that in ASP.NET, you need to ask on a different forum, this is a windows-forms forum.

This is because coping files in asp.net is a different story - as you find out, there are permission issues - you can't access the 'server' file system via any web-page - you need to set for the user IO permissions on the IIS, etc. this is not a simple task and you need to consult with experts from that field.

file.copy does not copy the folders or directory. i tried using file.copy but gave me an error. i used the following code:

File.Copy(@"Y:\EHRO", @"C:\Pooja");

The error coming is:   The target file "C:\Pooja" is a directory, not a file.

Answer 11

File.Copy only copies files. no built-in method in .NET to copy folder, but you can do that easily by going through the files in the folder.

 

here is an example:

If you need to copy sub folders as well, check out this example:

hi Chk this out. Here is a simple way..

Sub CopyDirectory(ByVal SourcePath As String, ByVal DestPath As String, Optional ByVal Overwrite As Boolean = False)

    Dim SourceDir As DirectoryInfo = New DirectoryInfo(SourcePath)

    Dim DestDir As DirectoryInfo = New DirectoryInfo(DestPath)



    ' the source directory must exist, otherwise throw an exception

    If SourceDir.Exists Then

      ' if destination SubDir's parent SubDir does not exist throw an exception

      If Not DestDir.Parent.Exists Then

        Throw New DirectoryNotFoundException _

          ("Destination directory does not exist: " + DestDir.Parent.FullName)

      End If



      If Not DestDir.Exists Then

        DestDir.Create()

      End If



      ' copy all the files of the current directory

      Dim ChildFile As FileInfo

      For Each ChildFile In SourceDir.GetFiles()

        If Overwrite Then

          ChildFile.CopyTo(Path.Combine(DestDir.FullName, ChildFile.Name), True)

        Else

          ' if Overwrite = false, copy the file only if it does not exist

          ' this is done to avoid an IOException if a file already exists

          ' this way the other files can be copied anyway...

          If Not File.Exists(Path.Combine(DestDir.FullName, ChildFile.Name)) Then

            ChildFile.CopyTo(Path.Combine(DestDir.FullName, ChildFile.Name), False)

          End If

        End If

      Next



      ' copy all the sub-directories by recursively calling this same routine

      Dim SubDir As DirectoryInfo

      For Each SubDir In SourceDir.GetDirectories()

        CopyDirectory(SubDir.FullName, Path.Combine(DestDir.FullName, _

          SubDir.Name), Overwrite)

      Next

    Else

      Throw New DirectoryNotFoundException("Source directory does not exist: " + SourceDir.FullName)

    End If

  End Sub
