Trying to copy all files/directories inside a directory to a new location that I create.
Users select the 'backup drive' to work with to in a combobox, then when they click the backup desktop button it simply creates a backup directory on that drive and copies all the files into that directory.
The backup directory gets created on the drive appropriately - but the first file it hits it kicks off an error.
private void backupDesktopButton_Click(object sender, EventArgs e)
{
//set the destionationLocation to the selectedDrive
string selectedDrive = backupDriveCombo.SelectedItem.ToString();
string destinationLocation = selectedDrive+"Backups-" + DateTime.Now.Month.ToString()+"-"+DateTime.Now.Year.ToString()+"\\Desktop\\";
if (!Directory.Exists(destinationLocation))
{
Directory.CreateDirectory(destinationLocation);
}
string desktopFolder = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
string[] fileList = Directory.GetFiles(desktopFolder);
foreach (string file in fileList)
{
//move the file
File.Copy(file, destinationLocation);
}
}
I get the error:
IOException was unhandled.
The filename, directory name, or volume label syntax is incorrect.
In the 'Autos' window (VS2010) I see the locations are set correctly:
destinationLocation = the appropriate directory (C:\Backups-8-2016\Desktop\)
file = the appropriate first file (C:\Users\myusername\Desktop\myshortcut.url)
What am I missing? I have all rights to be able to copy/paste/create things and the directory to store it gets created - just a problem moving the file.
From the documentation https://msdn.microsoft.com/en-us/library/c6cfw35a(v=vs.110).aspx
the second parameter:
The name of the destination file. This cannot be a directory or an existing file.
you need to concat the filename to the folder.
Try something like this
string[] fileList = Directory.GetFiles(desktopFolder);
foreach (string file in fileList)
{
string targetFile = Path.Combine(destinationLocation, Path.GetFileName(file));
if (File.Exists(targetFile)) File.Delete(targetFile);
File.Copy(file, targetFile);
}
I am trying to zip a folder using IonicZip library in C#. It is able to zip .txt, .exe, .pdf etc. in the folder, but not able to zip folder in folder.
It is able to zip MusicLogs.txt and Video.exe but cannot Music folder.Music folder contains some folder also. It doesnt see Music folder even while debugging. My code is :
string zipPath = #"C:\" + DateTime.Now.ToString("yyyy-MM-dd HH-mm") + ".zip"; // zipped file extracts here
string filename = #"E:\"; // the fodler which should be zipped. File must be exist
using (ZipFile zipFile = new ZipFile())
{
zipFile.Password = "asd";
zipFile.Encryption = EncryptionAlgorithm.PkzipWeak;
foreach (string file in Directory.GetFiles(filename)) // this foreach is for getting all files in a folder.
{
zipFile.AddFile(file, "YESMusic"); // set file
}
zipFile.Save(zipPath);
}
Where is the problem ? Need a change in AddFile function ? Thanks
This will work:
using (ZipFile zipFile = new ZipFile())
{
zipFile.Password = "asd";
zipFile.Encryption = EncryptionAlgorithm.PkzipWeak;
// Adding folders in the base directory
foreach (var item in Directory.GetDirectories(filename))
{
string folderName = new DirectoryInfo(item).Name;
zipFile.AddDirectory(item, folderName);
}
// Adding files in the base directory
foreach (string file in Directory.GetFiles(filename))
{
zipFile.AddFile(file);
}
zipFile.Save(zipPath);
}
I'm trying make a program that extracts a specific zip file everytime the program launches.
this is my code to create the zip file:
//creating the file
ZipFile File = new ZipFile(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\ABCD.zip");
//Adding files
File.AddFile(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\ab.dat", "");
File.AddFile(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\cd.dat", "");
//Save the file
File.Save();
I want to Extract the files ab.dat and cd.dat from ABCD.zip to the .exe file directory automatically.
Thanks for helping.
Taken mostly from the DotNetZip documentation:
private void Extract()
{
//Zip Location
string zipToUnpack = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\ABCD.zip";
// .EXE Directory
string unpackDirectory = System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetExecutingAssembly().Location);
using (ZipFile zip = ZipFile.Read(zipToUnpack))
{
foreach (ZipEntry e in zip)
{
//If filename matches
if (e.FileName == "ab.dat" || e.FileName == "cd.dat")
e.Extract(unpackDirectory, ExtractExistingFileAction.OverwriteSilently);
}
}
}
You can also filter the results using ExtractSelectEntries by selecting the files there:
zip.ExtractSelectedEntries("name = 'ab.dat' OR name = 'cd.dat'", "\", unpackDirectory, ExtractExistingFileAction.OverwriteSilently)
Or selecting all .dat files with a wildcard
zip.ExtractSelectedEntries("name = '*.dat'", "\", unpackDirectory, ExtractExistingFileAction.OverwriteSilently)
Use each ZipEntry's FileName property to see if it has the name you would like to extract.
Background: I'm developing a WinForms application using C# with an OpenFileDialog & FileBrowserDialog that will 1) search for a specific string in the filenames of a specified source directory 2) copy files to consolidated directory 3) convert multiple files from excel to csv files, and then 3) convert all the generated csv files into 1 big csv file using a command line executable
Example: MSDN provides a code example that lists all of the directories and files that begin with the letter "c" in "c:\". at http://msdn.microsoft.com/en-us/library/ms143448.aspx so I based my code on that...
Problem: The code doesn't copy any files to the consolidated folder so I'm pretty sure the search doesn't work.
What should I change on here? It doesn't work :
string files = "*.xlsx";
void DirSearch(string sDir)
{
try
{
foreach (string d in Directory.GetDirectories(sDir))
{
foreach (string f in Directory.GetFiles(d, files))
{
// Is this the file we are looking for?
// check excel files for corp name in the filename.
if (f.Contains(m_sc.get_Corp()))
{
// check if thread is cancelled
if (m_EventStop.WaitOne(0, true))
{
// clean-up operations may be placed here
// ...
// inform main thread that this thread stopped
m_EventStopped.Set();
return;
}
else
{
string path = sDir;
string searchPattern = m_sc.get_Corp();
// A file has been found in this directory
DirectoryInfo di = new DirectoryInfo(path);
DirectoryInfo[] directories = di.GetDirectories(searchPattern, SearchOption.TopDirectoryOnly);
foreach (FileInfo file in files)
{
try
{
// Copy each selected xlsx files into the specified TargetFolder
System.IO.File.Copy(FileName, consolidatedFolder + #"\" + System.IO.Path.GetFileName(FileName));
Log("File" + FileName + " has been copied to " + consolidatedFolder + #"\" + System.IO.Path.GetFileName(sourceFileOpenFileDialog.FileName));
// Convert each selected XLSX File to CSV Using the command prompt code...
}
}
}
}
The code you've posted does two separate search loops:
first:
foreach (string d in Directory.GetDirectories(sDir))
{
foreach (string f in Directory.GetFiles(d, files))
{
// Is this the file we are looking for?
// check excel files for corp name in the filename.
if (f.Contains(m_sc.get_Corp()))
{
then within that it also does:
string path = sDir;
string searchPattern = m_sc.get_Corp();
// A file has been found in this directory
DirectoryInfo di = new DirectoryInfo(path);
DirectoryInfo[] directories = di.GetDirectories(searchPattern, SearchOption.TopDirectoryOnly);
foreach (FileInfo file in files)
{
In the first one you are looking for files matching m_sc.get_Corp();, in the second one you are lookinf for directories...
In fact... your code (pseudo-code?) makes no sense...
Try:
taking your time
tidying up the code yourself
if you rewrite it slowly and break this into smaller chunks, you might spot what you are doing wrong.
Try cleaning up a bit, below is some code that will put you on the path, I've excluded the CSV conversion and the merge, hopefully you will get the idea.
private void YourFileRoutine(string sourceDirectoryPath, string consolidatedDirectoryPath)
{
var excelFiles = new DirectoryInfo(sourceDirectoryPath).GetFiles().Where(x => x.Extension == ".xlsx");
//Copy all Excel Files to consolidated Directory
foreach (var excelFile in excelFiles)
{
FileInfo copiedFile = excelFile.CopyTo(String.Concat(consolidatedDirectoryPath, excelFile.Name)); // Make sure consolidatedDirectoryPath as a "\" maybe use Path.Combine()?
// ConvertToCSV( Do your CSV conversion here, the Path will be = Path.GetFullPath(copiedFile);
}
// Merge CSV's
var csvFiles = new DirectoryInfo(consolidatedDirectoryPath).GetFiles().Where(x => x.Extension == ".csv");
// SomeMergeMethod that iterates through this FileInfo collection?
}
I need to copy a file to another path, leaving the original where it is.
I also want to be able to rename the file.
Will FileInfo's CopyTo method work?
Have a look at File.Copy()
Using File.Copy you can specify the new file name as part of the destination string.
So something like
File.Copy(#"c:\test.txt", #"c:\test\foo.txt");
See also How to: Copy, Delete, and Move Files and Folders (C# Programming Guide)
Yes. It will work: FileInfo.CopyTo Method
Use this method to allow or prevent overwriting of an existing file. Use the CopyTo method to prevent overwriting of an existing file by default.
All other responses are correct, but since you asked for FileInfo, here's a sample:
FileInfo fi = new FileInfo(#"c:\yourfile.ext");
fi.CopyTo(#"d:\anotherfile.ext", true); // existing file will be overwritten
I tried to copy an xml file from one location to another. Here is my code:
public void SaveStockInfoToAnotherFile()
{
string sourcePath = #"C:\inetpub\wwwroot";
string destinationPath = #"G:\ProjectBO\ForFutureAnalysis";
string sourceFileName = "startingStock.xml";
string destinationFileName = DateTime.Now.ToString("yyyyMMddhhmmss") + ".xml"; // Don't mind this. I did this because I needed to name the copied files with respect to time.
string sourceFile = System.IO.Path.Combine(sourcePath, sourceFileName);
string destinationFile = System.IO.Path.Combine(destinationPath, destinationFileName);
if (!System.IO.Directory.Exists(destinationPath))
{
System.IO.Directory.CreateDirectory(destinationPath);
}
System.IO.File.Copy(sourceFile, destinationFile, true);
}
Then I called this function inside a timer_elapsed function of certain interval which I think you don't need to see. It worked. Hope this helps.
You could also use File.Copy to copy and File.Move to rename it afterwords.
// Copy the file (specify true or false to overwrite or not overwrite the destination file if it exists.
File.Copy(mySourceFileAndPath, myDestinationFileAndPath, [true | false]);
// EDIT: as "astander" notes correctly, this step is not necessary, as File.Copy can rename already...
// However, this code could be adapted to rename the original file after copying
// Rename the file if the destination file doesn't exist. Throw exception otherwise
//if (!File.Exists(myRenamedDestinationFileAndPath))
// File.Move(myDestinationFileAndPath, myRenamedDestinationFileAndPath);
//else
// throw new IOException("Failed to rename file after copying, because destination file exists!");
EDIT
Commented out the "rename" code, because File.Copy can already copy and rename in one step, as astander noted correctly in the comments.
However, the rename code could be adapted if the OP desired to rename the source file after it has been copied to a new location.
string directoryPath = Path.GetDirectoryName(destinationFileName);
// If directory doesn't exist create one
if (!Directory.Exists(directoryPath))
{
DirectoryInfo di = Directory.CreateDirectory(directoryPath);
}
File.Copy(sourceFileName, destinationFileName);
File::Copy will copy the file to the destination folder and File::Move can both move and rename a file.
This is what I did to move a test file from the downloads to the desktop.
I hope its useful.
private void button1_Click(object sender, EventArgs e)//Copy files to the desktop
{
string sourcePath = #"C:\Users\UsreName\Downloads";
string targetPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string[] shortcuts = {
"FileCopyTest.txt"};
try
{
listbox1.Items.Add("Starting: Copy shortcuts to dektop.");
for (int i = 0; i < shortcuts.Length; i++)
{
if (shortcuts[i]!= null)
{
File.Copy(Path.Combine(sourcePath, shortcuts[i]), Path.Combine(targetPath, shortcuts[i]), true);
listbox1.Items.Add(shortcuts[i] + " was moved to desktop!");
}
else
{
listbox1.Items.Add("Shortcut " + shortcuts[i] + " Not found!");
}
}
}
catch (Exception ex)
{
listbox1.Items.Add("Unable to Copy file. Error : " + ex);
}
}
TO Copy The Folder I Use Two Text Box To Know The Place Of Folder And Anther Text Box To Know What The Folder To Copy It And This Is The Code
MessageBox.Show("The File is Create in The Place Of The Programe If you Don't Write The Place Of copy And You write Only Name Of Folder");// It Is To Help The User TO Know
if (Fromtb.Text=="")
{
MessageBox.Show("Ples You Should Write All Text Box");
Fromtb.Select();
return;
}
else if (Nametb.Text == "")
{
MessageBox.Show("Ples You Should Write The Third Text Box");
Nametb.Select();
return;
}
else if (Totb.Text == "")
{
MessageBox.Show("Ples You Should Write The Second Text Box");
Totb.Select();
return;
}
string fileName = Nametb.Text;
string sourcePath = #"" + Fromtb.Text;
string targetPath = #"" + Totb.Text;
string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
string destFile = System.IO.Path.Combine(targetPath, fileName);
if (!System.IO.Directory.Exists(targetPath))
{
System.IO.Directory.CreateDirectory(targetPath);
//when The User Write The New Folder It Will Create
MessageBox.Show("The File is Create in "+" "+Totb.Text);
}
System.IO.File.Copy(sourceFile, destFile, true);
if (System.IO.Directory.Exists(sourcePath))
{
string[] files = System.IO.Directory.GetFiles(sourcePath);
foreach (string s in files)
{
fileName = System.IO.Path.GetFileName(s);
destFile = System.IO.Path.Combine(targetPath, fileName);
System.IO.File.Copy(s, destFile, true);
}
MessageBox.Show("The File is copy To " + Totb.Text);
}
Old Question,but I would like to add complete Console Application example, considering you have files and proper permissions for the given folder, here is the code
class Program
{
static void Main(string[] args)
{
//path of file
string pathToOriginalFile = #"E:\C-sharp-IO\test.txt";
//duplicate file path
string PathForDuplicateFile = #"E:\C-sharp-IO\testDuplicate.txt";
//provide source and destination file paths
File.Copy(pathToOriginalFile, PathForDuplicateFile);
Console.ReadKey();
}
}
Source: File I/O in C# (Read, Write, Delete, Copy file using C#)
File.Move(#"c:\filename", #"c:\filenamet\filename.txt");
