I want to keep the last path which is selected. This is the code:
private void testFileButton_Click(object sender, EventArgs e)
{
fd = new OpenFileDialog();
fd.FileName = testParameters.testFileFile;
fd.InitialDirectory = testParameters.testFileDir;
if (fd.ShowDialog() == DialogResult.OK)
{
try
{
if (fd.SafeFileName != null)
{
testParameters.testFileDir = Path.GetDirectoryName(fd.FileName);
testParameters.testFileFile = Path.GetFileName(fd.FileName);
testFileLabel.Text = fd.FileName;
}
}
catch (IOException)
{
MessageBox.Show("Error: Could not read file");
}
}
}
to be able to keep the last selected path, I tried to add RestorDirectory and index but I did not get any result:
private void testFileButton_Click(object sender, EventArgs e)
{
fd = new OpenFileDialog();
fd.FileName = testParameters.testFileFile;
fd.InitialDirectory = testParameters.testFileDir;
fd.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
fd.FilterIndex = 2;
fd.RestoreDirectory = true;
if(...){
...
}
}
then I tried to use "else" instead:
private void testFileButton_Click(object sender, EventArgs e)
{
fd = new OpenFileDialog();
fd.FileName = testParameters.testFileFile;
fd.InitialDirectory = testParameters.testFileDir;
if (fd.ShowDialog() == DialogResult.OK)
{
try
{
if (fd.SafeFileName != null)
{
testParameters.testFileDir = Path.GetDirectoryName(fd.FileName);
testParameters.testFileFile = Path.GetFileName(fd.FileName);
testFileLabel.Text = fd.FileName;
}
}
}
catch (IOException)
{
MessageBox.Show("Error: Could not read file");
}
}
else
{
openFileDialog1.InitialDirectory = #"C:\";
}
}
but again without any result..
Does anyone have any idea?

The documentation states:
true if the dialog box restores the current directory to its original value if
the user changed the directory while searching for files; otherwise, false.
Update: Changing my answer a little, since I think I may have misunderstood your intention:
If I'm not mistaken, your dialog will open to fd.InitialDirectory each time you open it, since that is per definition the default for a new instance of fd. I believe this might be your problem here: You are calling fd = new OpenFileDialog(); each time you are trying to open it.
If you change your code to use the same instance for fd each time (define it in an outer scope, and e.g. access a singleton instance via a Property?), it might remember it's previous directory itself - that is the default behavior (which you can override using the RestoreDirectory property).
Example of getting a singleton instance: This will only instantiate the dialog once, and return the same instance each time you call the property:
Private OpenFileDialog _fd;
private OpenFileDialog SingleFd {
get { return _fd ?? (_fd = new OpenFileDialog()); }
}
// Now in your method, use:
var singleInstance = SingleFd;
You are not using same variable for file dialog everywhere. Like in if block you are showing file dialog fd, but in else part you are using variable openFileDialog. I couldn't understand why you are doing this, or probably it is a typo. Use same variable at both place if you want to set initial directory to "C:\" if user cancels the dialog.
Instead of creating instance in every call, create an instance once and use it for subsequent calls.
Regarding directory restore, if we don't set initial directory, by default it restores the previous directory, even for the different instances.
OpenFileDialog initially uses the current directory which is a process-wide setting. You have overridden this behavior by setting the InitialDirectory. Just don't do that and it will work.
If you want to persist the last directory used across process restarts, capture Environment.CurrentDirectory and save it. Set it before opening the dialog.
Note, that the current directory is a process-wide setting so that different parts of the app can interfere. Also, all relative paths are interpreted relative to this directory (which is why relative path are usually a bug waiting).
string path = #"C:\";
OpenFileDialog fd = new OpenFileDialog();
fd.FileName = "SelectFolder";
fd.InitialDirectory =path;
fd.ValidateNames = false;
fd.CheckFileExists = false;
if (fd.ShowDialog() == DialogResult.OK)
{
try
{
if (fd.SafeFileName != null)
{
string txt1 = System.IO.Path.GetFullPath(fd.FileName),
txt2 = txt1.Replace("SelectFolder", "").Trim();
testFileLabel.Text = txt2.Replace(path, "").Replace(#"\", ""); ;
}
}
catch (IOException)
{
MessageBox.Show("Error: Could not read file");
}
}
The Solution is to set the InitialDirectory path Blank
openFileDialog.InitialDirectory = ""
openFileDialog.RestoreDirectory = True

I have collected a code in c# for browsing files and folders in windows. My sample code segment is as follows:
void ButtonbrowseOnClick(object obj, EventArgs ea)
{
int size = -1;
DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.
if (result == DialogResult.OK) // Test result.
{
string file = openFileDialog1.FileName;
try
{
string text = File.ReadAllText(file);
size = text.Length;
}
catch (IOException)
{
}
}
Console.WriteLine(size); // <-- Shows file size in debugging mode.
Console.WriteLine(result); // <-- For debugging use.
}
But, I am getting the following error:
The name 'openFileDialog1' does not exist in the current context
What's wrong in the code segment?
It does not exist cause it hasn't been defined.
OpenFileDialog openFileDialog1 = new OpenFileDialog();
Are you sure you have defined the openFileDialog1? Changing the second line of your method to the bellow, seems to solve the problem
void ButtonbrowseOnClick(object obj, EventArgs ea)
{
int size = -1;
OpenFileDialog openFileDialog1 = new OpenFileDialog(); //define the variable
DialogResult result = openFileDialog1.ShowDialog();
//your code
Hey there i started learning C# a few days ago and I'm trying to make a program that copies and pastes files (and replaces if needed) to a selected directory but I don't know how to get the directory and file paths from the openfiledialog and folderbrowserdialog
what am I doing wrong?
Here's the code:
namespace filereplacer
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void direc_Click(object sender, EventArgs e)
{
string folderPath = "";
FolderBrowserDialog directchoosedlg = new FolderBrowserDialog();
if (directchoosedlg.ShowDialog() == DialogResult.OK)
{
folderPath = directchoosedlg.SelectedPath;
}
}
private void choof_Click(object sender, EventArgs e)
{
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
choofdlog.ShowDialog();
}
private void replacebtn_Click(object sender, EventArgs e)
{
// This is where i'm having trouble
}
public static void ReplaceFile(string FileToMoveAndDelete, string FileToReplace, string BackupOfFileToReplace)
{
File.Replace(FileToMoveAndDelete, FileToReplace, BackupOfFileToReplace, false);
}
}
For OpenFileDialog:
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
if (choofdlog.ShowDialog() == DialogResult.OK)
{
string sFileName = choofdlog.FileName;
string[] arrAllFiles = choofdlog.FileNames; //used when Multiselect = true
}
For FolderBrowserDialog:
FolderBrowserDialog fbd = new FolderBrowserDialog();
fbd.Description = "Custom Description";
if (fbd.ShowDialog() == DialogResult.OK)
{
string sSelectedPath = fbd.SelectedPath;
}
To access selected folder and selected file name you can declare both string at class level.
namespace filereplacer
{
public partial class Form1 : Form
{
string sSelectedFile;
string sSelectedFolder;
public Form1()
{
InitializeComponent();
}
private void direc_Click(object sender, EventArgs e)
{
FolderBrowserDialog fbd = new FolderBrowserDialog();
//fbd.Description = "Custom Description"; //not mandatory
if (fbd.ShowDialog() == DialogResult.OK)
sSelectedFolder = fbd.SelectedPath;
else
sSelectedFolder = string.Empty;
}
private void choof_Click(object sender, EventArgs e)
{
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
if (choofdlog.ShowDialog() == DialogResult.OK)
sSelectedFile = choofdlog.FileName;
else
sSelectedFile = string.Empty;
}
private void replacebtn_Click(object sender, EventArgs e)
{
if(sSelectedFolder != string.Empty && sSelectedFile != string.Empty)
{
//use selected folder path and file path
}
}
....
}
NOTE:
As you have kept choofdlog.Multiselect=true;, that means in the OpenFileDialog() you are able to select multiple files (by pressing ctrl key and left mouse click for selection).
In that case you could get all selected files in string[]:
At Class Level:
string[] arrAllFiles;
Locate this line (when Multiselect=true this line gives first file only):
sSelectedFile = choofdlog.FileName;
To get all files use this:
arrAllFiles = choofdlog.FileNames; //this line gives array of all selected files
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 = System.IO.Path.GetDirectoryName(choofdlog.FileName);
you can store the Path into string variable like
string s = choofdlog.FileName;
To get the full file path of a selected file or files, then you need to use FileName property for one file or FileNames property for multiple files.
var file = choofdlog.FileName; // for one file
or for multiple files
var files = choofdlog.FileNames; // for multiple files.
To get the directory of the file, you can use Path.GetDirectoryName
Here is Jon Keet's answer to a similar question about getting directories from path
Create this class as Extension:
public static class Extensiones
{
public static string FolderName(this OpenFileDialog ofd)
{
string resp = "";
resp = ofd.FileName.Substring(0, 3);
var final = ofd.FileName.Substring(3);
var info = final.Split('\\');
for (int i = 0; i < info.Length - 1; i++)
{
resp += info[i] + "\\";
}
return resp;
}
}
Then, you could use in this way:
//ofdSource is an OpenFileDialog
if (ofdSource.ShowDialog(this) == DialogResult.OK)
{
MessageBox.Show(ofdSource.FolderName());
}
Your choofdlog holds a FileName and FileNames (for multi-selection) containing the file paths, after the ShowDialog() returns.
A primitive quick fix that works.
If you only use OpenFileDialog, you can capture the FileName, SafeFileName, then subtract to get folder path:
exampleFileName = ofd.SafeFileName;
exampleFileNameFull = ofd.FileName;
exampleFileNameFolder = ofd.FileNameFull.Replace(ofd.FileName, "");
I am sorry if i am late to reply here but i just thought i should throw in a much simpler solution for the OpenDialog.
OpenDialog ofd = new OpenDialog();
var fullPathIncludingFileName = ofd.Filename; //returns the full path including the filename
var fullPathExcludingFileName = ofd.Filename.Replace(ofd.SafeFileName, "");//will remove the filename from the full path
I have not yet used a FolderBrowserDialog before so i will trust my fellow coders's take on this. I hope this helps.
String fn = openFileDialog1.SafeFileName;
String path = openFileDialog1.FileName.ToString().Replace(fn, "");
I need to use an specific file from the ones you select from a file dialog.
OpenFileDialog ofd = new OpenFileDialog();
private void pictureBox23_Click(object sender, EventArgs e)
{
ofd.Filter = "WAV|*.wav";
this.ofd.Multiselect = true;
if (ofd.ShowDialog() == DialogResult.OK)
{
label23.Text = ofd.SafeFileName;
}
else
{
label23.Text = "No files selected...";
}
}
What i need to do is select and use the files I pre-define, so if I define an event with 01.wav if the user selects a file named 01.wav, that one will be used like so:
using (SoundPlayer player = new SoundPlayer(Beatpadpc.Properties.Resources._01))
{
player.Play();
}
I currently have it adapted as it will play it from the resources, what i need to do is to play the file from the file selecion, but only if the file is named "01".wav
Is there a way for doing it?
Well, just filter the ofd property called Filenames.
OpenFileDialog ofd = new OpenFileDialog();
string strAudioFilePath = String.Empty;
private void pictureBox23_Click(object sender, EventArgs e)
{
ofd.Filter = "WAV|*.wav";
this.ofd.Multiselect = true;
if (ofd.ShowDialog() == DialogResult.OK)
{
// Here you make a small filter with linq
label23.Text = strAudioFilePath = ofd.FileNames.FirstOrDefault(x => x.EndsWith("01.wav")); // you change 01.wav to something that make more sense to you
}
else
{
label23.Text = "No files selected...";
}
}
Then if you want to get rid of your resource file, just give your sound player the path of the file and that's all.
SoundPlayer simpleSound = new SoundPlayer(strAudioFilePath);
simpleSound.Play();
i have application with Listbox and files, each time i press on Add button the default C drive open and i want the application to remember the last path i used
private void btnAdd_Click(object sender, EventArgs e)
{
System.IO.Stream myStream;
OpenFileDialog thisDialog = new OpenFileDialog();
thisDialog.InitialDirectory = "c:\\";
thisDialog.Filter = "(*.snoop, *.pcap, *.cap, *.net)|*.snoop; *.pcap; *.cap; *.net|" + "All files (*.*)|*.*";
thisDialog.FilterIndex = 1;
thisDialog.RestoreDirectory = false;
thisDialog.Multiselect = true; // Allow the user to select multiple files
thisDialog.Title = "Please Select Source File";
thisDialog.FileName = lastPath;
List<string> list = new List<string>();
if (thisDialog.ShowDialog() == DialogResult.OK)
{
foreach (String file in thisDialog.FileNames)
{
try
{
if ((myStream = thisDialog.OpenFile()) != null)
{
using (myStream)
{
listBoxFiles.Items.Add(file);
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
}
}
Save the last directory used in a global variable like this:
private string _lastPath = string.Empty;
then after the file selection initialize it:
if(thisDialog.Filenames.Length > 0)
_lastPath = Path.GetDirectoryName(thisDialog.Filenames[0]);
when you reopen the dialog set the InitialDirectory with this check:
thisDialog.InitialDirectory = (_lastPath.Length > 0 ? _lastPath: "c:\\");
and remove the thisDialog.FileName = lastPath;
EDIT --- UPDATE OF YOUR CODE ---
// This at the global level of your form
private string _lastPath = string.Empty;**
private void btnAdd_Click(object sender, EventArgs e)
{
System.IO.Stream myStream;
OpenFileDialog thisDialog = new OpenFileDialog();
thisDialog.InitialDirectory = (_lastPath.Length > 0 ? _lastPath: "c:\\");
thisDialog.Filter = "(*.snoop, *.pcap, *.cap, *.net)|*.snoop; *.pcap; *.cap; *.net|" + "All files (*.*)|*.*";
thisDialog.FilterIndex = 1;
thisDialog.RestoreDirectory = false;
thisDialog.Multiselect = true; // Allow the user to select multiple files
thisDialog.Title = "Please Select Source File";
thisDialog.FileName = lastPath;
List<string> list = new List<string>();
if (thisDialog.ShowDialog() == DialogResult.OK)
{
if(thisDialog.Filenames.Length > 0)
_lastPath = Path.GetDirectoryName(thisDialog.Filenames[0]);
foreach (String file in thisDialog.FileNames)
{
try
{
if ((myStream = thisDialog.OpenFile()) != null)
{
using (myStream)
{
listBoxFiles.Items.Add(file);
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
}
}
You can use a Visual Studio have the last path value for every execution of the application.
Only have to go to Project Properties->Configuration and add a value descriptor.
Example:
Name = LastPath; Type = string; Scope = User; Value = "Default path";
And then after you rebuild yout application, you can set this property this way:
Settings.Default.LastPath = LastPathSelected;
later, you can retrieve the value with:
thisDialog.InitialDirectory = Settings.Default.LastPath;
thisDialog.InitialDirectory = Path.GetDirectoryName(lastPath);
Yes, you can use the OpenFileDialog.InitialDirectory property. Note: you are setting the directory and not the file. So be sure to remove the filename from the path.
more info here
remove this line and you have the last path
thisDialog.InitialDirectory = "c:\\";
This is similar to older posts on this site but I keep getting an error message. I want to create a button in C # WPF that opens a dialogbox and saves a text file to be read at a later date. This code works for windows 32, but crashes on windows 64. How can I change this code to get it to work on both systems? I am a beginner at programming.
Microsoft.Win32.SaveFileDialog saveFile = new Microsoft.Win32.SaveFileDialog(); //throws error message here
private void savebutton_Click(object sender, RoutedEventArgs e)
{
saveFile.FileName = Class1.stringjobnum;
saveFile.Filter = "CCurtain (*.cur)|*.cur";
saveFile.FilterIndex = 2;
saveFile.InitialDirectory = "T:\\Tank Baffle Curtain Calculator\\SavedTanks";
saveFile.OverwritePrompt = true;
bool? result = saveFile.ShowDialog();
if (result.HasValue && result.Value)
{
clsSaveFile.s_FilePath = saveFile.FileName;
int iDotLoc = clsSaveFile.s_FilePath.LastIndexOf('.');
string strExtTest = clsSaveFile.s_FilePath.Substring(iDotLoc);
if (strExtTest != ".cur")
clsSaveFile.s_FilePath += ".cur";
FileInfo sourceFile = new FileInfo(clsSaveFile.s_FilePath);
clsSaveFile.saveFile();
}
}
You're setting an invalid FilterIndex, that might have something to do with it.
There is no 2nd filter in the filter string as written:
"CCurtain (*.cur)|*.cur"
Try setting the FilterIndex to 1 or adding another filter to the string.
You should try adding a catch around the statement to get a better idea as to what is going on.
try
{
code here
}
catch (Exception ex)
{
ex.message contains the info
}
Also, check for null:
bool? result = saveFile.ShowDialog();
if (result != null && (result.HasValue && result.Value))
{
// code
}
I would create the dialogbox IN the event. And you don't have two different filters.
private void savebutton_Click(object sender, RoutedEventArgs e)
{
Microsoft.Win32.SaveFileDialog saveFile = new Microsoft.Win32.SaveFileDialog();
saveFile.FileName = Class1.stringjobnum;
saveFile.Filter = "CCurtain|*.cur";;
saveFile.FilterIndex = 1;
saveFile.InitialDirectory = "T:\\Tank Baffle Curtain Calculator\\SavedTanks";
saveFile.OverwritePrompt = true;
// Show open file dialog box
Nullable<bool> result = saveFile.ShowDialog();
// Process open file dialog box results
if (result == true)
{
string filename = saveFile.FileName;
// are you sure you need to check the extension.
// if so extension is a a fileinfo property
}
