Can i get the full path from a filename such as get the full directory path from test.txt, Or is there a way i can save it
The reason im asking this is im making a application like Notepad++ some of you may of heard of it. When changing the tab control tab I want the form's text to be the full directory while the tabs text is just filename.format
My so far code
private void tabControl1_TabIndexChanged(object sender, EventArgs e)
{
if (tabControl1.SelectedTab.Text.StartsWith("New"))
{
int count = tabControl1.TabCount - 1;
this.Text = tabControl1.Controls[count].Text + " - My Note 1.0";
}
//It is a directory and i need to make the forms text the path here?
}
You can use System.IO.Path.GetFullPath:
var fullPath = Path.GetFullPath("test.txt");
If you pass in a short file name, it is expanded to a long file name.
If c:\temp\newdir is the current directory, calling GetFullPath on a file name such as test.txt returns c:\temp\newdir\test.txt.
And if you want to get path from that you use System.IO.Path.GetDirectoryName
var path = Path.GetDirectoryName(fullPath)
I think you should probably keep the full path and get the filename from the full path rather than the other way around. The key is to use a type representing a document, and let the tab view that document. If each tab refers to a document, and each document knows its full path, then you can get the short filename from the documents full path.
public class Document
{
public string FullPath { get; set; } // Full path to file, null for unsaved
public string FileName
{
get { return Path.GetFileName(FullPath); }
}
}
When a new tab is focused, get the document for the active tab and set the forms title from the FullPath of the document.
private void tabControl1_TabIndexChanged(object sender, EventArgs e)
{
Document activeDoc = GetDocumentFromActiveTab();
// Update win title with full path of active doc.
this.Text = (activeDoc.FullPath ?? "Unsaved document") + " MyApp" + version;
}
EDIT:
The key here is of course the method GetDocumentFromActiveTab() which isn't shown. You need to implement the data structures that manage your documents, and connects them to tabs. I did not include that in the answer, you need to try yourself. One idea is to make a type representing the entire application state including all tabs and documents.
public class Workspace
{
private Dictionary<SomeTypeOfView, Document> documentsOpenInViews;
// Methods to register a document to a tab, get document for a tab
// remove tab+document when tab is closed etc.
}
// not sure if this is what you want
say your filename with path is
string strFFL = #"C:\path\filename.format";
Console.WriteLine(System.IO.Path.GetFileName(strFFL)); //->filename.format
Console.WriteLine(System.IO.Path.GetDirectoryName(strFFL)); //-> C:\path
http://msdn.microsoft.com/en-us/library/system.io.path.getfilename(v=vs.110).aspx
http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname(v=vs.110).aspx
I think this is actually backwards. I think you want to keep a full path to the file and be able to display the filename only on the tab. So I think you want Path.GetDirectory name.
From: http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname(v=vs.110).aspx
string filePath = #"C:\MyDir\MySubDir\myfile.ext";
string directoryName;
int i = 0;
while (filePath != null)
{
directoryName = Path.GetDirectoryName(filePath);
Console.WriteLine("GetDirectoryName('{0}') returns '{1}'",
filePath, directoryName);
filePath = directoryName;
if (i == 1)
{
filePath = directoryName + #"\"; // this will preserve the previous path
}
i++;
}
/*
This code produces the following output:
GetDirectoryName('C:\MyDir\MySubDir\myfile.ext') returns 'C:\MyDir\MySubDir'
GetDirectoryName('C:\MyDir\MySubDir') returns 'C:\MyDir'
GetDirectoryName('C:\MyDir\') returns 'C:\MyDir'
GetDirectoryName('C:\MyDir') returns 'C:\'
GetDirectoryName('C:\') returns ''

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 have a functionality where I would scan a given path for a certain file and process some information based on the information in that file . this file info.json in json syntax has a name and a relative path to a certain directory .
What I am trying to do is simply obtain the relative path from the json file and print out an absoulute path
the relative file specified in the info.json file is as below,
{
"Name": "testName",
"OriginalPath": "new/File"
}
The absolute path that I am trying to print out is something like :- D:\testDel\new\File but the actual value is always something like D:\testDel\new/File , while I must say this path is still a valid path (when I do a win key + R I can navigate to that directory) but in terms of how its been displayed it looks messy .
Any Idea as to why I might be facing this problem , am I doing something wrong ,
my code is as follows
string path = #"D:\testDel";
IEnumerable<string> foundFiles = Directory.EnumerateFiles(path, "info.json", SearchOption.AllDirectories);
foreach (string file in foundFiles)
{
DataModel data = JsonConvert.DeserializeObject<DataModel>(File.ReadAllText(file));
string Name = data.Name;
string absolutePath = data.OriginalPath;
string folderpath = Path.GetDirectoryName(file);
string fullPath = Path.Combine(folderpath, absolutePath);
Console.WriteLine(fullPath);
}
public class DataModel
{
public string Name { get; set; }
public string OriginalPath { get; set; }
}
Wrap the Path.Combine(folderpath, absolutePath) statement in a Path.GetFullPath() as
fullPath=Path.GetFullPath(Path.Combine(folderpath, absolutePath));
this will also resolve reletive paths like ../NewFil to D:\NewFile
You can update a path, coming from JSON using Replace method and built-in Path.AltDirectorySeparatorChar and Path.DirectorySeparatorChar fields
string absolutePath = data.OriginalPath.Replace(Path.AltDirectorySeparatorChar, Path.DirectorySeparatorChar);
string folderpath = Path.GetDirectoryName(file);
You are right, that path D:\testDel\new/File is valid, because Windows supports both, forward slash and backslash
How to get the string in the button text?
private void btn_open_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
ReadCSV(openFileDialog1.FileName);
btn_open.Text = "filename here";
string targetdirectory = "D:\\Projects";
string filename = Path.GetFileNameWithoutExtension(target directory);
}
thanks for your help
When you select a file using OpenFileDialog, the OpenFileDialog.FileName contains the full path of the file selected.
Path.GetFileNameWithoutExtension() does just that, getting the file name without extension. However you need to pass an actual file path, not a directory. If you pass a directory path, it will simply retrieve the innermost directory name which is not what your desired outcome.
So what you should do is;
Get file name from OpenFileDialog.
Pass that to the Path.GetFileNameWithoutExtension() method.
Set the resulting string as the button text.
Also the correct usage of ShowDialog() is to check the return value; it returns true if the user clicked OK button, and false otherwise.
if(openFileDialog1.ShowDialog() == true)
{
string file = Path.GetFileNameWithoutExtension(openFileDialog1.FileName);
btn_open.Text = file;
}
I've tested the code and the directory gets the correct input, but for some reason it can't find it. Is there something I'm missing why I can't find any directory?
Here is my code pretty simplistic as of right now.
public partial class Form1 : Form
{
string fileName;
string dirName;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
dirName = textBox1.Text;
fileName = textBox2.Text;
if (System.IO.Directory.Exists(dirName))
{
if (System.IO.File.Exists(fileName))
{
System.IO.File.Delete(fileName);
}
else
{
MessageBox.Show("Invalid Directory or File Name");
}
}
}
That's because I guess you're passing the directory path by an input control in this way "C:/examplePath/" and it should be declared in this way "C:\\examplePath" because the escape characters, and probably you'll get another error further because when you're asking for a file's existence, you must to declare it concatenating directory path plus filename (and its extension).
so the final string should be like this "c:\\exampleDir\\examplefile.ext"
or simply you should try:
dirName = string.Format("#{0}", textBox1.Text);
fullPathFile = string.Format("{0}/{1}", dirName, textBox2.Text);
And then you use "fullPathFile" instead of "fileName" variable.
Don't forget to debug your application for making sure what's the string values.
Based on your code, it appears fileName and dirName come from two different textbox controls. And you also dont do any sort of combining the file path (or so it appears). So when you call Directory.Exists() it makes sense that this would work but it can't find the file. When you use File.Exists() you need to pass in not only the file name but also the directory where its located. To do this use the Path.Combine() method.
if (System.IO.Directory.Exists(dirName))
{
string filePath = System.IO.Path.Combine(dirName, fileName);
if (System.IO.File.Exists(filePath))
{
System.IO.File.Delete(filePath);
}
else
{
MessageBox.Show("Invalid Directory or File Name");
}
}
I need some help in renaming some images in a directory located at /images/graphicsLib/.
All image names in /graphicsLib/ have naming convention that looks like this:
400-60947.jpg. We call the "400" part of the file the prefix and we call the "60957" part the suffix. The entire file name we call the sku.
So if you saw the contents of /graphicLib/ it would look like:
400-60957.jpg
400-60960.jpg
400-60967.jpg
400-60968.jpg
402-60988.jpg
402-60700.jpg
500-60725.jpg
500-60733.jpg
etc...
Using C# & System.IO , what is an acceptable way to rename all image files base on the prefix of the file name? Users need to be able to enter in the current prefix, see all images in the /graphicsLib/ that match, then enter in the new prefix to have all those files renamed with the new prefix. Only the prefix of the file gets renamed, the rest of the file name needs to be unchanged.
What I have so far is:
//enter in current prefix to see what images will be affected by
// the rename process,
// bind results to a bulleted list.
// Also there is a textbox called oldSkuTextBox and button
// called searchButton in .aspx
private void searchButton_Click(object sender, EventArgs e)
{
string skuPrefix = oldSkuTextBox.Text;
string pathToFiles = "e:\\sites\\oursite\\siteroot\\images\graphicsLib\\";
string searchPattern = skuPrefix + "*";
skuBulletedList.DataSource = Directory.GetFiles(pathToFiles, searchPattern);
skuBulletedList.DataBind();
}
//enter in new prefix for the file rename
//there is a textbox called newSkuTextBox and
//button called newSkuButton in .aspx
private void newSkuButton_Click(object sender, EventArgs e)
{
//Should I loop through the Items in my List,
// or loop through the files found in the /graphicsLib/ directory?
//assuming a loop through the list:
foreach(ListItem imageFile in skuBulletedList.Items)
{
string newPrefix = newSkuTextBox.Text;
//need to do a string split here?
//Then concatenate the new prefix with the split
//of the string that will remain changed?
}
}
You could look at string.Split.
Loop over all files in your directory.
string[] fileParts = oldFileName.Split('-');
This will give you an array of two strings:
fileParts[0] -> "400"
fileParts[1] -> "60957.jpg"
using the first name in your list.
Your new filename then becomes:
if (fileParts[0].Equals(oldPrefix))
{
newFileName = string.Format("(0)-(1)", newPrefix, fileParts[1]);
}
Then to rename the file:
File.Move(oldFileName, newFileName);
To loop over the files in the directory:
foreach (string oldFileName in Directory.GetFiles(pathToFiles, searchPattern))
{
// Rename logic
}
Actually you should iterate each of the files in the directory and rename one by one
To determine the new file name, you may use something like:
String newFileName = Regex.Replace("400-60957.jpg", #"^(\d)+\-(\d)+", x=> "NewPrefix" + "-" + x.Groups[2].Value);
To rename the file, you may use something like:
File.Move(oldFileName, newFileName);
