Copy file from one directory to another

Closed 5 years ago.
Okay, so I have a text box in my program where a user can enter a value, however I am wanting to call this value in another class.
public static void Main()
{
string sourceDirectory = #"F:\RootFolder\testingfolder\Test";
string targetDirectory = #"c:\targetDirectory"; //this is where the value would site
Copy(sourceDirectory, targetDirectory);
}
Not 100% sure on how to call this.
Edit
After some much needed research I have found the below to work for me;
private void CopyInstallFiles(object sender, EventArgs e)
{
string sourceDirectory = #"F:somepath";
string targetDirectory = directoryImput.Text;
//Copy all the files & Replaces any files with the same name
foreach (string newPath in System.IO.Directory.GetFiles(sourceDirectory, "*.*",
SearchOption.AllDirectories))
File.Copy(newPath, newPath.Replace(sourceDirectory, targetDirectory), true);

I just realized that you are looking for a method to move all files and folders - silly me. Here, have some example from https://msdn.microsoft.com/en-us/library/bb762914.aspx :
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);
}
}
}
}
Short version - place it in DirectoryManager.cs and call by DirectoryManager.CopyDirectory(source, destination):
using System.IO;
class DirectoryManager
{
internal static void CopyDirectory(string input, string output)
{
DirectoryInfo dir = new DirectoryInfo(input);
if (dir.Exists)
{
DirectoryInfo[] dirs = dir.GetDirectories();
Directory.CreateDirectory(output);
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)
{
string temppath = Path.Combine(output, file.Name);
file.CopyTo(temppath, false);
}
foreach (DirectoryInfo subdir in dirs)
{
string temppath = Path.Combine(output, subdir.Name);
CopyDirectory(subdir.FullName, temppath);
}
}
}
}

Move multiple selected files into specific folder

I have implemented a code like this from which I got the idea somewhere.
public string BrowseFolder()
{
string filePath = string.Empty;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Multiselect = true;
openFileDialog1.Title = "Browse EXCEL File";
openFileDialog1.Filter = "Excel Files (*.xlsx)|*.xlsx";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
filePath = openFileDialog1.FileName;
return Path.GetDirectoryName(filePath);
}
return null;
}
public void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
DirectoryInfo dir = new DirectoryInfo(sourceDirName);
DirectoryInfo[] dirs = dir.GetDirectories();
// If the source directory does not exist, throw an exception.
if (!dir.Exists)
{
throw new DirectoryNotFoundException(
"Source directory does not exist or could not be found: "
+ sourceDirName);
}
// If the destination directory does not exist, create it.
if (!Directory.Exists(destDirName))
{
Directory.CreateDirectory(destDirName);
}
// Get the file contents of the directory to copy.
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)
{
// Create the path to the new copy of the file.
string temppath = Path.Combine(destDirName, file.Name.ToString());
// Copy the file.
file.CopyTo(temppath, false);
}
// If copySubDirs is true, copy the subdirectories.
if (copySubDirs)
{
foreach (DirectoryInfo subdir in dirs)
{
// Create the subdirectory.
string temppath = Path.Combine(destDirName, subdir.Name);
// Copy the subdirectories.
DirectoryCopy(subdir.FullName, temppath, copySubDirs);
}
}
}
Ok let's assume that this two methods is in a class. I have easily understood how this codes work. It is copying all the files inside the folder I browse. This is not what I need. What I wanted to achieve is to copy only the selected files (multiple) in my folder.
I've tried to manipulate my code but I still didn't get the right solution. Thanks in advance.

foreach (string file in openFileDialog1.FileNames)
{
FileInfo fInfo = new FileInfo(file);
fInfo.MoveTo(newFilePath);
}
Ref: https://msdn.microsoft.com/en-us/library/system.windows.forms.filedialog.filenames(v=vs.110).aspx
https://msdn.microsoft.com/en-us/library/system.io.fileinfo.moveto(v=vs.110).aspx

You need to get all the files selected from OpenFileDialog like this:
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string[] filesSelected = openFileDialog1.FileNames;
}
The code above returns all the files that a user selected from the OpenFileDialog.

Copy the files from folders recursively with wildcard characters (folder path has wildcard characters)

Good day.
I have to copy all the files in folders (including sub folders) to other shared drive location for backup the data. The challenge, which I am facing is folder path with wildcard characters.
For example,
The folder structure is like below
D:/Folder1/Folder11/Folder111
D:/Folder2/Folder222/Folder222222
D:/Folder3/Folder333333/Folder3333333
I am looking for the input format should be "D:/Folder?/Folder*/Folder*". So that it has to loop according to the wildcard character patterns.
Can you please help me.
Regards,
Chandra

You can achive this with a simple RegularExpression. I've created an example which does the job for you.
The RegEx string is quite easy: [A-Z]:\\Folder[0-9]{1}\\Folder[0-9]{2}\\Folder[0-9]{3}
[A-Z]:\\Folder[0-9]{1}\\Folder[0-9]{2}\\Folder[0-9]{3}
----- -------- -------- --------
Drive 1x digit 2x digit 3x digit
See the sample at regexr.
EDIT:
//using System.IO;
public void CopyMatching(string drive)
{
try
{
var backuplocation = ""; //the path where you wanna copy your files to
var regex = new Regex(#"[A-Z]:\\Folder[0-9]{1}\\Folder[0-9]{2}\\Folder[0-9]{3}");
var directories = new List<string>();
foreach (var directory in Directory.EnumerateDirectories(drive))
{
if (regex.IsMatch(directory))
{
directories.Add(directory);
}
}
foreach (var directory in directories)
{
DirectoryCopy(directory, backuplocation, true);
}
}
catch (Exception)
{
throw;
}
}
And DirectoryCopy:
public 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);
}
}
}

IEnumerable<string> getMatchingSubDir(string dirPath, string pattern)
{
List<string> matchingFolders = new List<string>();
DirectoryInfo myDir = new DirectoryInfo(dirPath);
foreach (var subDir in myDir.GetDirectories(pattern))
{
matchingFolders.AddRange(getMatchingSubDir(subDir.FullName, pattern));
}
return matchingFolders;
}
Then this call will return you a list of all folders matching your pattern:
getMatchingSubDir("D:\\", "Folder*");

Copying from MSDN, there is the following solution. It recursively copies directories over from source to destination.
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);
DirectoryInfo[] dirs = dir.GetDirectories();
if (!dir.Exists)
{
throw new DirectoryNotFoundException(
"Source directory does not exist or could not be found: "
+ sourceDirName);
}
// 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);
}
}
}
}

Copying Files Recursively

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)

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);
}
}
}
}

A non-recursive replacement for this answer would be:
private static void DirectoryCopy(string sourceBasePath, string destinationBasePath, bool recursive = true)
{
if (!Directory.Exists(sourceBasePath))
throw new DirectoryNotFoundException($"Directory '{sourceBasePath}' not found");
var directoriesToProcess = new Queue<(string sourcePath, string destinationPath)>();
directoriesToProcess.Enqueue((sourcePath: sourceBasePath, destinationPath: destinationBasePath));
while (directoriesToProcess.Any())
{
(string sourcePath, string destinationPath) = directoriesToProcess.Dequeue();
if (!Directory.Exists(destinationPath))
Directory.CreateDirectory(destinationPath);
var sourceDirectoryInfo = new DirectoryInfo(sourcePath);
foreach (FileInfo sourceFileInfo in sourceDirectoryInfo.EnumerateFiles())
sourceFileInfo.CopyTo(Path.Combine(destinationPath, sourceFileInfo.Name), true);
if (!recursive)
continue;
foreach (DirectoryInfo sourceSubDirectoryInfo in sourceDirectoryInfo.EnumerateDirectories())
directoriesToProcess.Enqueue((
sourcePath: sourceSubDirectoryInfo.FullName,
destinationPath: Path.Combine(destinationPath, sourceSubDirectoryInfo.Name)));
}
}

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);
}
