Extracting Path from OpenFileDialog path/filename - c#

I'm writing a little utility that starts with selecting a file, and then I need to select a folder. I'd like to default the folder to where the selected file was.
OpenFileDialog.FileName returns the full path & filename - what I want is to obtain just the path portion (sans filename), so I can use that as the initial selected folder.
private System.Windows.Forms.OpenFileDialog ofd;
private System.Windows.Forms.FolderBrowserDialog fbd;
...
if (ofd.ShowDialog() == DialogResult.OK)
{
string sourceFile = ofd.FileName;
string sourceFolder = ???;
}
...
fbd.SelectedPath = sourceFolder; // set initial fbd.ShowDialog() folder
if (fbd.ShowDialog() == DialogResult.OK)
{
...
}
Are there any .NET methods to do this, or do I need to use regex, split, trim, etc??

Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.
Usage is simple.
string directoryPath = Path.GetDirectoryName(filePath);

how about this:
string fullPath = ofd.FileName;
string fileName = ofd.SafeFileName;
string path = fullPath.Replace(fileName, "");

if (openFileDialog1.ShowDialog(this) == DialogResult.OK)
{
strfilename = openFileDialog1.InitialDirectory + openFileDialog1.FileName;
}

You can use FolderBrowserDialog instead of FileDialog and get the path from the OK result.
FolderBrowserDialog browser = new FolderBrowserDialog();
string tempPath ="";
if (browser.ShowDialog() == DialogResult.OK)
{
tempPath = browser.SelectedPath; // prints path
}

Here's the simple way to do It !
string fullPath =openFileDialog1.FileName;
string directory;
directory = fullPath.Substring(0, fullPath.LastIndexOf('\\'));

This was all I needed for the full path to a file
#openFileDialog1.FileName

How to make sure user select specific folder and remove file extension from files in the selected folder?

What I have here is the user select a folder full of .txt files from a external drive and a dummy file is made with the filename to a local folder.
I have 2 questions regarding the code below.
How do I verify that the user select a specific folder?
How do I remove the .txt extension? The code copies the file name and creates the files but its labeled "text.txt.png" but I need it to read "text.png".
int g;
private void folderSelect()
{
FolderBrowserDialog folder = new FolderBrowserDialog();
folder.RootFolder = Environment.SpecialFolder.MyComputer;
folder.ShowNewFolderButton = false;
folder.Description = "Select Folder";
if (folder.ShowDialog() == DialogResult.OK)
{
DirectoryInfo files = new DirectoryInfo(folder.SelectedPath);
FileInfo[] textFiles = files.GetFiles("*.txt");
while (g < textFiles.Length)
{
if (g <= textFiles.Length)
{
File.Create("path/" + (textFiles[g].Name + ".png"));
g++;
}
else
{
break;
}
}
}
Note: I tried using Path.GetFileNameWithoutExtension to remove the extension but Im not sure if i was using it correctly.
Any help would be appreciated. Thank you in advance.
const string NEW_PATH = "path/";
if (!Directory.Exists(NEW_PATH))
Directory.CreateDirectory(NEW_PATH);
const string PATH_TO_CHECK = "correctpath";
FolderBrowserDialog folder = new FolderBrowserDialog();
folder.RootFolder = Environment.SpecialFolder.MyComputer;
folder.ShowNewFolderButton = false;
folder.Description = "Select Folder";
if (folder.ShowDialog() == DialogResult.OK)
{
string pathPastDrive = folder.SelectedPath.Substring(Path.GetPathRoot(folder.SelectedPath).Length).ToLower();
// Here it depends on whether you want to check (1) that the path is EXACTLY what you want,
// or (2) whether the selected path just needs to END in the path that you want.
/*1*/ if (!pathPastDrive == PATH_TO_CHECK)
/*2*/ if (!pathPastDrive.EndsWith(PATH_TO_CHECK))
return; // or you can throw an exception if you want
foreach (string textFile in Directory.GetFiles(folder.SelectedPath, "*.txt"))
File.Create(NEW_PATH + Path.GetFileNameWithoutExtension(textFile) + ".png");
}
You can use GetFileNameWithoutExtension, and it makes it pretty easy.
Also, if you're already sure that your new folder exists, then you can elide the first three lines and replace NEW_PATH with "path/" in the last line.
To see the returned path just use the SelectedPath property, then you can compare it to whatever you had in mind. The # before the path just means I don't have to escape any characters, it's the same as "C:\\MyPath".
FolderBrowserDialog folder = new FolderBrowserDialog();
if (folder.ShowDialog() == DialogResult.OK)
{
if (folder.SelectedPath == #"C:\MyPath")
{
// DO SOMETHING
}
}
You already hit the nail on the head about the file name without extension, change this line:
File.Create("path/" + (textFiles[g].Name + ".png"));
To this:
File.Create("path/" + (Path.GetFileNameWithoutExtension(textFiles[g].Name) + ".png"));
Edit:
To get the folder name you already have the DirectoryInfo object so just use that:
DirectoryInfo files = new DirectoryInfo(folder.SelectedPath);
string folderName = files.Name;

Always asking file not present in bin/debug folder

Is there any way i can take the data from the original location instead of copying the file to the bin/debug folder.
I am looking to send a file to my local printer. But my C# application is allowing to send file only when i copy the file to my bin/debug folder. Is there a way i can over come!!!
Codes:
private string image_print()
{
OpenFileDialog ofd = new OpenFileDialog();
{
InitialDirectory = #"C:\ZTOOLS\FONTS",
Filter = "GRF files (*.grf)|*.grf",
FilterIndex = 2,
RestoreDirectory = true
};
if (ofd.ShowDialog() == DialogResult.OK)
{
string filename_noext = Path.GetFileName(ofd.FileName);
string path = Path.GetFullPath(ofd.FileName);
img_path.Text = filename_noext;
string replacepath = #"bin\\Debug";
string fileName = Path.GetFileName(path);
string newpath = Path.Combine(replacepath, fileName);
if (!File.Exists(filename_noext))
{
// I don't like to copy the file to the debug folder
// is there an alternative solution?
File.Copy(path, newpath);
if (string.IsNullOrEmpty(img_path.Text))
{
return "";
}
StreamReader test2 = new StreamReader(img_path.Text);
string s = test2.ReadToEnd();
return s;
}
}
}
private void button4_Click(object sender, EventArgs e)
{
string s = image_print() + Print_image();
if (!String.IsNullOrEmpty(s) &&
!String.IsNullOrEmpty(img_path.Text))
{
PrintFactory.sendTextToLPT1(s);
}
}
Try this:
private string image_print()
{
string returnValue = string.Empty;
var ofd = new OpenFileDialog();
{
InitialDirectory = #"C:\ZTOOLS\FONTS",
Filter = "GRF files (*.grf)|*.grf",
FilterIndex = 2,
RestoreDirectory = true
};
if (ofd.ShowDialog() == DialogResult.OK &&
!string.IsNullOrWhiteSpace(ofd.FileName) &&
File.Exists(ofd.FileName))
{
img_path.Text = Path.GetFileName(ofd.FileName);
using (var test2 = new StreamReader(ofd.FileName))
{
returnValue = test2.ReadToEnd();
}
}
return returnValue;
}
It looks like the underlying issue is caused by these lines:
filename_noext = System.IO.Path.GetFileName(ofd.FileName); //this actually does include the extension!! It does not include the fully qualified path
...
img_path.Text = filename_noext;
...
StreamReader test2 = new StreamReader(img_path.Text);
You are getting the full file path from the OpenFileDialog then setting img_path.Text to just the file name. You are then using that filename (no path) to open the file for reading.
When you open a new StreamReader with just a filename it will look in the current directory for the file (relative to the location of the EXE, in this case bin/debug). Copying to "bin/debug" will probably not work in any other environment outside of your machine as the EXE will probably be deployed somewhere else.
You should use the full path to the selected file:
if (ofd.ShowDialog() == DialogResult.OK)
{
path = Path.GetFullPath(ofd.FileName);
img_path.Text = path;
if (string.IsNullOrEmpty(img_path.Text))
return "";//
StreamReader test2 = new StreamReader(img_path.Text);
string s = test2.ReadToEnd();
return s;
}

How can I save Image files in in my project folder?

In my Windows application, I have a PictureBox and a Button control. I want to load an Image file from user from the button's OnClick event and save that image file in a folder name "proImg" which is in my project. Then I want to show that image in the PictureBox.
I have written this code, but it is not working:
OpenFileDialog opFile = new OpenFileDialog();
opFile.Title = "Select a Image";
opFile.Filter = "jpg files (*.jpg)|*.jpg|All files (*.*)|*.*";
if (opFile.ShowDialog() == DialogResult.OK)
{
try
{
string iName = opFile.FileName;
string filepath = "~/images/" + opFile.FileName;
File.Copy(iName,Path.Combine("~\\ProImages\\", Path.GetFileName(iName)));
picProduct.Image = new Bitmap(opFile.OpenFile());
}
catch (Exception exp)
{
MessageBox.Show("Unable to open file " + exp.Message);
}
}
else
{
opFile.Dispose();
}
It's not able to save the image in the "proImg" folder.
Actually the string iName = opFile.FileName; is not giving you the full path. You must use the SafeFileName instead. I assumed that you want your folder on your exe directory also. Please refer to my modifications:
OpenFileDialog opFile = new OpenFileDialog();
opFile.Title = "Select a Image";
opFile.Filter = "jpg files (*.jpg)|*.jpg|All files (*.*)|*.*";
string appPath = Path.GetDirectoryName(Application.ExecutablePath) + #"\ProImages\"; // <---
if (Directory.Exists(appPath) == false) // <---
{ // <---
Directory.CreateDirectory(appPath); // <---
} // <---
if (opFile.ShowDialog() == DialogResult.OK)
{
try
{
string iName = opFile.SafeFileName; // <---
string filepath = opFile.FileName; // <---
File.Copy(filepath, appPath + iName); // <---
picProduct.Image = new Bitmap(opFile.OpenFile());
}
catch (Exception exp)
{
MessageBox.Show("Unable to open file " + exp.Message);
}
}
else
{
opFile.Dispose();
}
You should provide a correct destination Path to File.Copy method. "~\ProImages..." is not a correct path. This example will copy selected picture to folder ProImages inside the project's bin folder :
string iName = opFile.FileName;
File.Copy(iName, Path.Combine(#"ProImages\", Path.GetFileName(iName)));
the path is relative to current executable file's location, except you provide full path (i.e. #"D:\ProImages").
In case you didn't create the folder manually and want the program generate ProImages folder if it doesn't exist yet :
string iName = opFile.FileName;
string folder = #"ProImages\";
var path = Path.Combine(folder, Path.GetFileName(iName))
if (!Directory.Exists(folder))
{
Directory.CreateDirectory(folder);
}
File.Copy(iName, path);
PS: Notice the use of verbatim (#) to automatically escape backslash (\) characters in string. It is common practice to use verbatim when declaring string that represent path.
Try using picturebox.Image.Save function. In my program it is working
PictureBox.Image.Save(Your directory, ImageFormat.Jpeg)
example
pictureBox2.Image.Save(#"D:/CameraImge/"+foldername+"/"+ numbering + ".jpg", ImageFormat.Jpeg);
You write code like this.
string appPath = Path.GetDirectoryName(Application.ExecutablePath) +foldername ;
pictureBox1.Image.Save(appPath + #"\" + filename + ".jpg", ImageFormat.Jpeg);

How to get full file path from file name?

How do I get the full path for a given file?
e.g. I provide:
string filename = #"test.txt";
Result should be:
Full File Path = C:\Windows\ABC\Test\test.txt
Try
string fileName = "test.txt";
FileInfo f = new FileInfo(fileName);
string fullname = f.FullName;
Use Path.GetFullPath():
http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx
This should return the full path information.
You Can use:
string path = Path.GetFullPath(FileName);
it will return the Full path of that mentioned file.
Directory.GetCurrentDirectory
string dirpath = Directory.GetCurrentDirectory();
Prepend this dirpath to the filename to get the complete path.
As #Dan Puzey indicated in the comments, it would be better to use Path.Combine
Path.Combine(Directory.GetCurrentDirectory(), filename)
I know my answer it's too late, but it might helpful to other's
Try,
Void Main()
{
string filename = #"test.txt";
string filePath= AppDomain.CurrentDomain.BaseDirectory + filename ;
Console.WriteLine(filePath);
}
try..
Server.MapPath(FileUpload1.FileName);
try:
string fileName = #"test.txt";
string currentDirectory = Directory.GetCurrentDirectory();
string[] fullFilePath = Directory.GetFiles(currentDirectory, filename, SearchOption.AllDirectories);
it will return full path of all such files in the current directory and its sub directories to string array fullFilePath. If only one file exist it will be in "fullFileName[0]".
private const string BulkSetPriceFile = "test.txt";
...
var fullname = Path.GetFullPath(BulkSetPriceFile);
You can get the current path:
string AssemblyPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location).ToString();
Good luck!

copy all type format file from folder in c#

I am trying to copy all format file (.txt,.pdf,.doc ...) file from source folder to destination.
I have write code only for text file.
What should I do to copy all format files?
My code:
string fileName = "test.txt";
string sourcePath = #"E:\test222";
string targetPath = #"E:\TestFolder";
string sourceFile = System.IO.Path.Combine(sourcePath, fileName);
string destFile = System.IO.Path.Combine(targetPath, fileName);
Code to copy file:
System.IO.File.Copy(sourceFile, destFile, true);
Use Directory.GetFiles and loop the paths
string sourcePath = #"E:\test222";
string targetPath = #"E:\TestFolder";
foreach (var sourceFilePath in Directory.GetFiles(sourcePath))
{
string fileName = Path.GetFileName(sourceFilePath);
string destinationFilePath = Path.Combine(targetPath, fileName);
System.IO.File.Copy(sourceFilePath, destinationFilePath , true);
}
I kinda got the impression you wanted to filter by extension. If so, this will do it. Comment out the parts I indicate below if you don't.
string sourcePath = #"E:\test222";
string targetPath = #"E:\TestFolder";
var extensions = new[] {".txt", ".pdf", ".doc" }; // not sure if you really wanted to filter by extension or not, it kinda seemed like maybe you did. if not, comment this out
var files = (from file in Directory.EnumerateFiles(sourcePath)
where extensions.Contains(Path.GetExtension(file), StringComparer.InvariantCultureIgnoreCase) // comment this out if you don't want to filter extensions
select new
{
Source = file,
Destination = Path.Combine(targetPath, Path.GetFileName(file))
});
foreach(var file in files)
{
File.Copy(file.Source, file.Destination);
}
string[] filePaths = Directory.GetFiles(#"E:\test222\", "*", SearchOption.AllDirectories);
use this, and loop through all the files to copy into destination folder
