rename file by adding an incrementing number to old file name c#

I'm writing my first Cocoa app in c#, its suppose to append/add numbers at the begging of a file name.
Users give only the path to the folder (for example with music), and for each file included in folder the program suppose to add incrementing numbers like
001_(old_fileName),
002_(old_fileName),
...,
092_(old_fileName)
etc,
Untill the end of files in given folder (by path).
There is no way to split a file name, cause file names are not known (may even include numbers itself). I've tried few possible options to solve this, but non of them works. Found few already asked question with changing names in c# but non of the results actually helped me.
The code under is the rest I've got at the moment, all non-working tries were firstly commented and later deleted. by NSAlert i see the path/name of each file in folder as a help. I would be more than happy to receive help
void RenameFunction()
{
string sPath = _Path_textBox.StringValue;
if (Directory.Exists(sPath))
{
var txtFiles = Directory.EnumerateFiles(sPath);
var txt2Files = Directory.GetFiles((sPath));
string fileNameOnly = Path.GetFileNameWithoutExtension(sPath);
string extension = Path.GetExtension(sPath);
string path = Path.GetDirectoryName(sPath);
string newFullPath = sPath;
int count = 1;
while (File.Exists(sPath))//newFullPath))
{
string tempFileName = string.Format(count + "_" + fileNameOnly + sPath);
//count++;
//string.Format("{0}{0}{0}{1}", fileNameOnly, count++);
newFullPath = Path.Combine(path, extension + tempFileName);
count++;
}
string[] fileEntities = Directory.GetFiles(newFullPath); //GetFileSystemEntries(sPath);//GetFiles(sPath);
//foreach (var _songName in fileEntities)
//{
// string tempFileName = count + "_" + fileNameOnly + sPath;
// //string.Format("{0}{0}{0}{1}", fileNameOnly, count++);
// newFullPath = Path.Combine(sPath ,extension + tempFileName);
// File.Move(sPath, newFullPath);
//}
foreach (var _songName in fileEntities)
{
AmountofFiles(_songName);
}
}
}
void AmountofFiles(string path)
{
var alert2 = new NSAlert();
alert2.MessageText = "mp3";
alert2.InformativeText = "AMOUNT OF MP3 FILES IS '{1}' : " + path;
alert2.RunModal();
}

Have you try use File.Move? Just move file to same path, but another name
File.Move("NameToBeRename.jpg","NewName.jpg");

There are multiple things which are not right with the code you share. The thing which want to achieve can be implemented using very simple approach.
All you need to do is retrieve all the files names with the full path from the directory and rename them one by one.
Follow the below code which demonstrates the above mentioned approach.
// Path of the directory.
var directroy = _Path_textBox.StringValue;
if (Directory.Exists(directroy))
{
//Get all the filenames with full path from the directory.
var filePaths = Directory.EnumerateFiles(directroy);
//Variable to append number in front of the file name.
var count = 1;
//Iterate thru all the file names
foreach (var filePath in filePaths)
{
//Get only file name from the full file path.
var fileName = Path.GetFileName(filePath);
//Create new path with the directory path and new file name.
var destLocation = Path.Combine(directory, count + fileName);
//User File.Move to move file to the same directory with new name.
File.Move(filePath, destLocation);
//Increment count.
count++;
}
}
I hope this helps you to resolve your issue.

Change former path to custom path keeping the filename and create a file using stream writer in c#

I am creating multiple files using StreamWriter, I want these files to be created in a specific directory
StreamWriter w = new StreamWriter(File.Create(name + ".txt"));
w.WriteLine(name);
w.Close();
here name is variable that is used as file name and also to be written in that file, but my problem is I want this file to be created in specific directory.

Use Path.Combine
Path.Combine uses the Path.PathSeparator and it checks whether the first path has already a separator at the end so it will not duplicate the separators. Additionally, it checks whether the path elements to combine have invalid chars.
Quoted from this SO post
Also it would be fruitful to check if you name variable contains invalid characters for a filename.
You may first remove invalid characters from name variable using Path.GetInvalidFileNameChars method :
var invalidChars = Path.GetInvalidFileNameChars();
string invalidCharsRemoved = new string(name
.Where(x => !invalidChars.Contains(x))
.ToArray());
Quoted from this SO post
string directory = "c:\\temp";
Instead of
File.Create(name + ".txt")
Use
string filename = invalidCharsRemoved + ".txt"
File.Create(Path.Combine(directory , filename ))

You can include the path too:
string path = "C:\\SomeFolder\\";
File.Create( path + name + ".txt");
Or Use Path.Combine like:
File.Create( Path.Combine(path, name + ".txt") );

FileStream fileStream = null;
StreamWriter writer = null;
try
{
string folderPath = #"D:\SpecificDirecory\";
string path = Path.Combine(folderPath , "fileName.txt");
if (!Directory.Exists(folderPath))
{
Directory.CreateDirectory(folderPath);
}
fileStream = new FileStream(#path, FileMode.Create);
writer = new StreamWriter(fileStream);
writer.Write(fileBuilder.ToString());
}
catch (Exception ex)
{
throw ex;
}
finally
{
writer.Close();
fileStream.Close();
}

name contains some thing like #"U:\TDScripts\acchf122_0023"
ok according to the new information from your comment you need actually to get rid of the old path and directory.
You can use the Path.GetFileNameWithoutExtension method to achieve that. After that you can use Path.Combine to create your own path.
Here is an example to demonstrate this:
string myDirectory = #"C:\temp";
string oldPathWithName = #"U:\TDScripts\acchf122_0023";
string onlyFileName = Path.GetFileNameWithoutExtension(oldPathWithName);
string myNewPath = Path.Combine(myDirectory, onlyFileName + ".txt");
Console.WriteLine(myNewPath);
I hope this solves your problem.

You can declare a path for your directory like this :
string path = #"c:\folder\....";
Then with the following command:
File.Create( path + name + ".txt");
You will get what you want

place same file type in a folder

I am using Magick.NET and C# Console. The code below finds all the .eps file and then converting it to .jpg.
foreach (string fileName in Directory.GetFiles("C:/Users/Adrian/Documents/Visual Studio 2010/Projects/ImageMagickTest/ImageMagickTest/bin/Debug/eps","*.eps"))
{
using (MagickImage image = new MagickImage())
{
Console.WriteLine("\n\nNow Converting. Please Wait...\n\n");
image.Read(fileName, settings);
image.Write(fileName.Substring(0,fileName.Length - 3) + ".jpg");
i++;
Console.WriteLine("Conversion Success.\n\n");
Console.WriteLine("Files Converted: " + i);
}
}
Now, what I want is to separate .eps from .jpg.
for example:
folder /eps/ contents:
image1.eps
image2.eps
after executing the loop. the folder /eps/ contents will be:
image1.eps
image2.eps
image1.jpg
image2.jpg
How will i place the .jpg in a different folder?

I'm assuming you want a jpg folder? Add this to create the folder before your foreach loop.
if (!Directory.Exists("C:/Users/Adrian/Documents/Visual Studio 2010/Projects/ImageMagickTest/ImageMagickTest/bin/Debug/jpg"))
{
Directory.CreateDirectory("C:/Users/Adrian/Documents/Visual Studio 2010/Projects/ImageMagickTest/ImageMagickTest/bin/Debug/jpg");
}
I'm also assuming image.Write will actually create the file, if so then you can change the following line
image.Write(fileName.Substring(0,fileName.Length - 3) + ".jpg");
To be something like this
image.Write(fileName.Substring(0,fileName.Length - 7) + "jpg/.jpg");

I think This code will give you exactly what you want
foreach (string fileName in Directory.GetFiles("Folder","*.eps"))
{
using (MagickImage image = new MagickImage())
{
Console.WriteLine("\n\nNow Converting. Please Wait...\n\n");
image.Read(fileName, settings);
string[] split = filename.Split('\\');
string clear_file_name = split[split.Length-1];
string split_file_name= clear_file_name.split('.');
string filename_without_extention = split_file_name[0];
if(!Directory.Exists(folder+"\\jpeg"))
Directory.Create(folder+"\\jpeg");
image.Write(fileName.Substring(0,folder+"\\jpeg\\"+file_name_without_extention+".jpg");
i++;
Console.WriteLine("Conversion Success.\n\n");
Console.WriteLine("Files Converted: " + i);
}
}

E.g.
// Set the source folder to whatever.
var sourceFolderPath = "...";
// Create the destination folder path by removing the leaf folder name and replacing it with another.
var destinationFolderPath = Path.Combine(Path.GetDirectoryName(sourceFolderPath), "jpg");
foreach (var sourceFilePath in Directory.GetFiles(sourceFolderPath, "*.eps"))
{
// Build the destination file path from the desitination folder path, file name and a new extension.
var destinationFilePath = Path.ChangeExtension(Path.Combine(destinationFolderPath, Path.GetFileName(sourceFilePath)), ".jpg");
// Use destinationFilePath here.
}

How save uploaded file? c# mvc

I want upload an image file to project's folder but I have an error in my catch:
Could not find a part of the path 'C:\project\uploads\logotipos\11111\'.
What am I do wrong? I want save that image uploaded by my client in that folder... that folder exists... ah if I put a breakpoint for folder_exists3 that shows me a true value!
My code is:
try
{
var fileName = dados.cod_cliente;
bool folder_exists = Directory.Exists(Server.MapPath("~/uploads"));
if(!folder_exists)
Directory.CreateDirectory(Server.MapPath("~/uploads"));
bool folder_exists2 = Directory.Exists(Server.MapPath("~/uploads/logo"));
if(!folder_exists2)
Directory.CreateDirectory(Server.MapPath("~/uploads/logo"));
bool folder_exists3 = Directory.Exists(Server.MapPath("~/uploads/logo/" + fileName));
if(!folder_exists3)
Directory.CreateDirectory(Server.MapPath("~/uploads/logo/"+fileName));
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName+"/"));
}
catch(Exception e)
{
}
Someone knows what I'm do wrong?
Thank you :)

Try this:
string targetFolder = HttpContext.Current.Server.MapPath("~/uploads/logo");
string targetPath = Path.Combine(targetFolder, yourFileName);
file.SaveAs(targetPath);

Your error is the following:
bool folder_exists3 = Directory.Exists(Server.MapPath("~/uploads/logo/" + fileName));
if(!folder_exists3)
Directory.CreateDirectory(Server.MapPath("~/uploads/logo/"+fileName));
You check if a directory exists, but you should check if the file exists:
File.Exists(....);

You need filename
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName+"/" + your_image_fillename));

Remove the last part of the path to save you have an extra "/"
It should be
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName);
Also you do not have a file extension set.

How to copy a file to another path?

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();
}
}
