Files and Directory C# - c#

Been working on file directory stuff in C# and I think i might just be forgetting something simple here. So lets says I have 4 folders and I need to check if the folder exists and then display the files within the folder. But the part that I'm stuck at is checking lets say the creationdate of a file WITH one of the four folders. Almost like I'm missing the path actual path to the file within the folder. Here the code that i had so far.
string end;
string directoryName;
string fileName;
string[] listOfFiles;
Console.Write("Enter the name of the folder: ");
directoryName = Console.ReadLine();
while (directoryName != "end")
{
if (Directory.Exists(directoryName))
{
Console.WriteLine("Directory exists, and it contains the following:");
listOfFiles = Directory.GetFiles(directoryName);
for (int x = 0; x < listOfFiles.Length; ++x)
Console.WriteLine(" {0}", listOfFiles[x]);
}
Console.Write("Enter a filename: ");
fileName = Console.ReadLine();
if(File.Exists(fileName)) // Almost like a path needs to be here.
{
Console.WriteLine("File was created " + File.GetCreationTime(fileName));
}
}
just thought incase it was asked the programs exe and folders are all located together

Your intuition is correct. File.Exists takes a full path (just like pretty much every other Filesystem API).
Add the path with Path.Combine(). See How do I join two paths in C#?
fileName = Console.ReadLine();
var filePath = Path.Combine(directoryName, fileName);
if (File.Exists(filePath)) // Almost like a path needs to be here - Yep!

How can I detect if there is any file in a folder using SSIS?

I receive every day a file with a specific pattern and extension, which I want to run under certain process. I want to check if there is any file in my folder, because otherwise I will do another task. So far I found that you can use a Script Task and do a File.Exist. However, I'm doing something wrong because it doesn't take the * as a wildcard.
Devoluciones_source is "C:\Users\us1\Folder\"
FileToSearch is "return"
My files:
return_20200102.csv
return_20200203.csv
String Filepath = Dts.Variables["$Project::Devoluciones_source"].Value.ToString() + Dts.Variables["User::FileToSearch"].Value.ToString() + "*csv";
if (
File.Exists(Filepath))
{
Dts.Variables["User::IsFound"].Value = 1;
}
I don't think File.Exits() accepts wildcards, it checks the literal filepath and will return false because C:\Users\us1\Folder\*.csv is not found.
What you could do instead is get the files in the folder C:\Users\us1\Folder\ and checking those agains a searchPattern using Directory.GetFiles(path, searchPattern)
Like this:
string dirPath = Dts.Variables["$Project::Devoluciones_source"].Value.ToString();
string fileName = Dts.Variables["User::FileToSearch"].Value.ToString();
// if you want to make sure the directory exists:
if(Directory.Exists(dirPath) {
string[] files = Directory.GetFiles(dirPath, fileName + "*.csv");
if(files.lenght > 0) {
// you can now iterate over each file that is found in the users directory that matches your pattern and do your logic.
}
}

Invalid Directory Slashes

I've got a bit of a weird issue going on right now. I am trying to load a localization json file from StreamingAssets. I am using Path.Combine to combine StreamingAssetsPath and Path together to form the full path. The value of Path is en-us. But for some reason Path.Combine is throwing a \ when concatting the strings so my path is invalid. If I change the value of Path to /en-US then it cuts the Application.StreamingAssetsPath portion off completely.
Debug.Log result of Path = en-US:
C:/Users/bluem/Documents/Fishtale/Assets/StreamingAssets\en-US
Debug.Log result of Path = /en-US
/en-US
I just cannot make heads or tales of this weirdness lol.
public void LoadLocalizedText()
{
localizedText = new Dictionary<string, string>();
string filePath = Path.Combine(Application.streamingAssetsPath, path);
Debug.Log(filePath);
if (File.Exists(filePath))
{
string dataAsJson = File.ReadAllText(filePath);
LocalizationData loadedData = JsonUtility.FromJson<LocalizationData>(dataAsJson);
for (int i = 0; i < loadedData.items.Length; i++)
{
localizedText.Add(loadedData.items[i].key, loadedData.items[i].value);
}
Debug.Log("Localization Manager: Data loaded, dictionary contains: " + localizedText.Count + " entries.");
}
else
{
Debug.LogError("Localization Manager: Cannot find data file name: " + filePath);
return;
}
isReady = true;
}
I will answer my own question. The responses provided were helpful, but not the solution to the problem.
The problem is not actually in the code, but rather the reference to the file being passed. The file needs to include the extension of .json or it simply will not find it. So in this case the answer is to change the value of Path from en-US to en-US.json.

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.

C# mass File renamer

i want to create C# mass file renamer, here is my UI
i have created tes folder, inside of tes there's a file which is 1.txt.
i want to create my program to add prefix and suffix to the files, so 1.txt will become
prefix1suffix
but then i got an error
it's said file already exist though there's only one file on tes folder, which is 1.txt how do i make it work ? where's the error comes from ?
i have tried the following code
private void Rename(string prefix, string filepath, string suffix)
{
//i don't use prefix suffix yet to make sure if my function works
DirectoryInfo d = new DirectoryInfo(filepath);
FileInfo[] file = d.GetFiles();
try
{
foreach (FileInfo f in file )
{
File.Move(f.FullName,"stackoverflow");
}
}
catch (Exception e)
{
cmd.cetakGagal(e.ToString(), title);
}
cmd.cetakSukses("Rename Success", title);
}
and it returns same error as the second picture above.
the following picture is tes folder, there's nothing in tes folder except 1.txt
You are calling File.Move() with a full path for your sourceFileName and a relative path for your destFileName. The relative file path is relative to the current working directory and not to the source file path. I expect that a stackoverflow file exists in the current working directory, most likely created the first time you ran this code.
your File.Move is changing them all to StackOverflow not using the prefix and suffix. If you only have one file in the directory it shouldn't be an issue. Are you sure there is only 1 file?
public static void Move(
string sourceFileName,
string destFileName
)
Looking at this answer might be the clue as you are specifying relative path for the destination file. To obtain the current working directory, see GetCurrentDirectory
The sourceFileName and destFileName arguments are permitted to specify
relative or absolute path information. Relative path information is
interpreted as relative to the current working directory.
You should change
File.Move(f.FullName,"stackoverflow");
to
string fileName = f.Name.Replace(f.Extenstion,string.Empty);
string newFileName = string.Format("{0}{1}{2}",prefix,fileName,suffix);
string newFileWithPath = Path.Combine(f.Directory,newFileName);
if (!File.Exists(newFileWithPath))
{
File.Move(f.FullName,newFileWithPath);
}
The code above will give you that error since, after the first run through, "stackoverflow" exists as a file. Make sure that you check if the destination file exists (using File.Exists) before calling File.Move.
Since your goal is renaming, I would suggest using a test folder filled with files rather than using a piecemeal approach. See if something like this helps:
private void Rename(string prefix, string filepath, string suffix)
{
//i don't use prefix suffix yet to make sure if my function works
DirectoryInfo d = new DirectoryInfo(filepath);
FileInfo[] file = d.GetFiles();
try
{
foreach (FileInfo f in file )
{
f.MoveTo(#filepath + #"\" + prefix + f.Name.Insert(f.Name.LastIndexOf('.'),suffix));
}
}
catch (Exception e)
{
cmd.cetakGagal(e.ToString(), title);
}
cmd.cetakSukses("Rename Success", title);
}
on a side note using a listview to display the filenames and the changes before they're committed will help prevent unwanted changes.

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");

return;
}
else if (Totb.Text == "")
{

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))
{

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");
