How to do this:
Check if folder upload exists (if nor then create it) ~/ uploads
Check if subfolder with username exists ~/uploads/folder with username
It as to check for each case individually because I could add a new user to the system and of course the folder uploads alredy exists, just need to create a sub folder with username
In short:
Use HttpServerUtility.MapPath to convert the virtual path (such as ~/uploads) to a physical path.
Use Directory.Exists to determine if the directory exists or not
If the directory does not exist, use Directory.CreateDirectory to create it.
string userName = ""; // Substitute with logic for obtaining username
string folder = ResolveUrl( "~/Uploads" );
folder = System.IO.Path.Combine( folder, userName );
if ( !System.IO.Directory.Exists( folder ) )
System.IO.Directory.CreateDirectory( folder );
try this:
var path = string.Format(#"{0}Uploads\{1}",Request.PhysicalApplicationPath,
HttpContext.Current.User.Identity.Name);
if (!Directory.Exists(path))
Directory.CreateDirectory(path);
You could try this :
using System;
using System.IO;
public void CreateDirectories(string uploadDirPath, string userName)
{
string userDirPath= uploadDirPath + "\\" + userName ;
if (!Directory.Exists(uploadDirPath))
{
Directory.CreateDirectory(uploadDirPath);
if (!Directory.Exists(userDirPath))
Directory.CreateDirectory (userDirPath);
}
}
I leave it to you to wrap this up by calling the method in loops according to you specific logic and paramaterizing user names and folders

Hi I have a code that you can save file and give specific file naming.
the problem is how can I check if file exist in the folder directory.
What I'm trying to do is like this.
FileInfo fileInfo = new FileInfo(oldPath);
if (fileInfo.Exists)
{
if (!Directory.Exists(newPath))
{
Directory.CreateDirectory(newPath);
}
fileInfo.MoveTo(string.Format("{0}{1}{2}", newPath, extBox1t.Text + "_" + textBox2.Text + "_" + textBox3.Text, fileInfo.Extension));
im trying to add MessageBox.Show in the below
if (!Directory.Exists(newPath))
{
MessageBox.Show("File Exist. Please Rename!");
Directory.CreateDirectory(newPath);
But it does not work. Or is there a way to add extension name at the last part of filename it should like this
Example: STACKOVERFLOWDOTCOME_IDNUM_11162022_0
if STACKOVERFLOWDOTCOME_IDNUM_11162022 exist it will rename to STACKOVERFLOWDOTCOME_IDNUM_11162022_0
it will add _0 at the last part.
One way to do it is to write a method that extracts the directory path, name, and extension of the file from a string that represents the full file path. Then we can create another variable to act as the "counter", which we'll use to add the number at the end of the file name (before the extension). We can then create a loop that checks if the file exists, and if it doesn't we'll increment the counter, insert it into the name, and try again.
For example:
public static string GetUniqueFileName(string fileFullName)
{
var path = Path.GetDirectoryName(fileFullName);
var name = Path.GetFileNameWithoutExtension(fileFullName);
var ext = Path.GetExtension(fileFullName);
var counter = 0;
// Keep appending a new number to the end of the file name until it's unique
while(File.Exists(fileFullName))
{
// Since the file name exists, insert an underscore and number
// just before the file extension for the next iteration
fileFullName = Path.Combine(path, $"{name}_{counter++}{ext}");
}
return fileFullName;
}
To test it out, I created a file at c:\temp\temp.txt. After running the program with this file path, it came up with a new file name: c:\temp\temp_0.txt
I am having a problem with coding my save-directory. I want it to create a folder called "Ausgabe" (Output) on the current users Desktop, but I do not know how to check if it already exists and if it doesn't then create it.
This is my current code for that part so far:
public partial class Form1 : Form
{
string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
// need some code here
}
What do I add in order to make it do what I want it to do?
You can check if a directory exists using
Directory.Exists(pathToDirectory)
and create a directory using
Directory.CreateDirectory(pathToDirectory)
EDIT In response to your comment:
string directoryPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Ausgabe")
should give you the path to a folder named 'Ausgabe' in the users Desktop-folder.
Just use Directory.CreateDirectory. If the directory exists the method will not create it (in other words it contains a call to Directory.Exists internally)
public partial class Form1 : Form
{
string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
public Form1()
{
string myFolder = Path.Combine(path, "Ausgabe");
Directory.CreateDirectory(myFolder);
}
To use this method you need to add a using System.IO to the top of your Form1.cs file.
I wish also to say that the Desktop is not the most appropriate place to create a directory for your application. There is a proper place provided by the System and it is under the ProgramData enum (CommonApplicationData or ApplicationData)
string path = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
As per this doc, the Directory.CreateDirectory Method (String) will
Creates all directories and subdirectories in the specified path
unless they already exist.
So it is fine to use like this:
string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string desktopFolder = Path.Combine(path, "New Folder");
Directory.CreateDirectory(desktopFolder);
You can use the Directory.Exists() method: https://msdn.microsoft.com/en-us/library/system.io.directory.exists(v=vs.110).aspx
Your code would propebly look something like this:
public static void Main()
{
// Specify the directory you want to manipulate.
string path = #"c:\MyDir";
try
{
// Determine whether the directory exists.
if (Directory.Exists(path))
{
Console.WriteLine("That path exists already.");
return;
}
// Try to create the directory.
DirectoryInfo di = Directory.CreateDirectory(path);
Console.WriteLine("The directory was created successfully at {0}.", Directory.GetCreationTime(path));
// Delete the directory.
di.Delete();
Console.WriteLine("The directory was deleted successfully.");
}
catch (Exception e)
{
Console.WriteLine("The process failed: {0}", e.ToString());
}
finally {}
}
I have had a recent issue so here is my solution,
I had to find the deployed directory
var deployedDir = Assembly.GetEntryAssembly().CodeBase;
deployedDir = Path.GetDirectoryName(deployedDir);
deployedDir = deployedDir.Replace("file:\\", "");
var pathToDirectory= Path.Combine(deployedDir, "YourFileName");
Then do what the above answers show and create the directory if it doesnt exist,
Directory.CreateDirectory(pathToDirectory)
it is my path example E:\test\img\sig.jpg
I want to get E:\test\img to create directory
i try split but it be img
so I try function Directory.CreateDirectory and the path is E:\test\img\sig.jpg\
say me a ideas?
The recommended way is to use Path.GetDirectoryName():
string file = #"E:\test\img\sig.jpg";
string path = Path.GetDirectoryName(file); // results in #"E:\test\img"
Use Path.GetDirectoryName which returns the directory information for the specified path string.
string directoryName = Path.GetDirectoryName(filePath);
The Path class contains a lot of useful methods for path handling, which are more reliable than manual string manipulation:
var directoryComponent = Path.GetDirectoryName(#"E:\test\img\sig.jpg");
// yields `E:\test\img`
For completeness, I'd like to mention Path.Combine, which does the opposite:
var dirAndFile = Path.Combine(#"E:\test\img", "sig.jpg");
// no more checking for trailing slashes, hooray!
To create the directory, you can use Directory.Create. Note that it is not necessary to check if the directory exists first.
You can try this code to find the directory name.
System.IO.FileInfo fi = new System.IO.FileInfo(#"E:\test\img\sig.jpg");
string dirname = fi.DirectoryName;
and to create the directory
Directory.CreateDirectory(dirname );
Another solution can be :
FileInfo f = new FileInfo(#"E:\test\img\sig.jpg");
if (f.Exists)
{
string dirName= f.DirectoryName;
}
Hello everyone and well met! I have tried a lot of different methods/programs to try and solve my problem. I'm a novice programmer and have taken a Visual Basic Class and Visual C# class.
I'm working with this in C#
I started off by making a very basic move file program and it worked fine for one file but as I mentioned I will be needing to move a ton of files based on name
What I am trying to do is move .pst (for example dave.pst) files from my exchange server based on username onto a backup server in the users folder (folder = dave) that has the same name as the .pst file
The ideal program would be:
Get files from the folder with the .pst extension
Move files to appropriate folder that has the same name in front of the .pst file extension
Update:
// String pstFileFolder = #"C:\test\";
// var searchPattern = "*.pst";
// var extension = ".pst";
//var serverFolder = #"C:\test3\";
// String filename = System.IO.Path.GetFileNameWithoutExtension(pstFileFolder);
// Searches the directory for *.pst
DirectoryInfo sourceDirectory = new DirectoryInfo(#"C:\test\");
String strTargetDirectory = (#"C:\test3\");
Console.WriteLine(sourceDirectory);
Console.ReadKey(true);>foreach (FileInfo file in sourceDirectory.GetFiles()) {
Console.WriteLine(file);
Console.ReadKey(true);
// Try to create the directory.
System.IO.Directory.CreateDirectory(strTargetDirectory);
file.MoveTo(strTargetDirectory + "\\" + file.Name);
}
This is just a simple copy procedure. I'm completely aware. The
Console.WriteLine(file);
Console.ReadKey(true);
Are for verification purpose right now to make sure I'm getting the proper files and I am. Now I just need to find the folder based on the name of the .pst file(the folder for the users are already created), make a folder(say 0304 for the year), then copy that .pst based on the name.
Thanks a ton for your help guys. #yuck, thanks for the code.
Have a look at the File and Directory classes in the System.IO namespace. You could use the Directory.GetFiles() method to get the names of the files you need to transfer.
Here's a console application to get you started. Note that there isn't any error checking and it makes some assumptions about how the files are named (e.g. that they end with .pst and don't contain that elsewhere in the name):
private static void Main() {
var pstFileFolder = #"C:\TEMP\PST_Files\";
var searchPattern = "*.pst";
var extension = ".pst";
var serverFolder = #"\\SERVER\PST_Backup\";
// Searches the directory for *.pst
foreach (var file in Directory.GetFiles(pstFileFolder, searchPattern)) {
// Exposes file information like Name
var theFileInfo = new FileInfo(file);
// Gets the user name based on file name
// e.g. DaveSmith.pst would become DaveSmith
var userName = theFileInfo.Name.Replace(extension, "");
// Sets up the destination location
// e.g. \\SERVER\PST_Backup\DaveSmith\DaveSmith.pst
var destination = serverFolder + userName + #"\" + theFileInfo.Name;
File.Move(file, destination);
}
}
System.IO is your friend in this case ;)
First, Determine file name by:
String filename = System.IO.Path.GetFileNameWithoutExtension(SOME_PATH)
To make path to new folder, use Path.Combine:
String targetDir = Path.Combine(SOME_ROOT_DIR,filename);
Next, create folder with name based on given fileName
System.IO.Directory.CreateDirectory(targetDir);
Ah! You need to have name of file, but with extension this time. Path.GetFileName:
String fileNameWithExtension = System.IO.Path.GetFileName(SOME_PATH);
And you can move file (by File.Move) to it:
System.IO.File.Move(SOME_PATH,Path.Combine(targetDir,fileNameWithExtension)
Laster already show you how to get file list in folder.
I personally prefer DirectoryInfo because it is more object-oriented.
DirectoryInfo sourceDirectory = new DirectoryInfo("C:\MySourceDirectoryPath");
String strTargetDirectory = "C:\MyTargetDirectoryPath";
foreach (FileInfo file in sourceDirectory.GetFiles())
{
file.MoveTo(strTargetDirectory + "\\" + file.Name);
}
I have a collection of files with fully qualified paths (root/test/thing1/thing2/file.txt). I want to foreach over this collection and drop the file into the location defined in the path, however, if certain directories don't exist, I want them to great created automatically. My program has a default "drop location", such as z:/. The "drop location" starts off empty, so in my example above, the first item should automatically create the directories needed to create z:/root/test/thing1/thing2/file.txt. How can I do this?
foreach (var relativePath in files.Keys)
{
var fullPath = Path.Combine(defaultLocation, relativePath);
var directory = Path.GetDirectoryName(fullPath);
Directory.CreateDirectory(directory);
saveFile(fullPath, files[relativePath]);
}
where files is IDictionary<string, object>.
string somepath = #"z:/root/test/thing1/thing2/file.txt";
System.IO.Directory.CreateDirectory(System.IO.Path.GetDirectoryName( ( somepath ) );
Directory.CreateDirectory("/root/...")
Creates all directories and subdirectories in the specified path
Check IO namespace (Directory, Path), I think they'll help you
using System.IO
Then check it..
string fileName =#"d:/root/test/thing1/thing2/file.txt";
string directory = Path.GetDirectoryName(fileName);
if (!Directory.Exists(directory))
Directory.CreateDirectory(directory);
string filename = "c:\\temp\\wibble\\wobble\\file.txt";
string dir = Path.GetDirectoryName(filename);
if (!Directory.Exists(dir))
{
Directory.CreateDirectory(dir);
}
File.Create(filename);
with suitable exception handling, of course.
I've found setting the "default location" at the start of execution to be helpful and reduce a bit of redundant code (e.g., Path.Combine(defaultLocation, relativePath)).
Example:
var defaultLocation = "z:/";
Directory.SetCurrentDirectory(defaultLocation);
Directory.SetCurrentDirectory(AppContext.BaseDirectory);
