Is there a way to get the file name of a file you open using the openfiledialog in C#? I need this because, the user is going to open an image file, but then the image file is added to a listbox(using its filename), then can be selected for display in a picturebox. Having trouble finding a solution for this.
Cheers.
Use OpenFileDialog.FileName:
if(openFileDialog.ShowDialog() == DialogResult.OK)
{
InsertIntoList(openFileDialog.FileName);
}
Have you tried using openfiledialog.FileName property?
use openFileDialog.SafeFileName to get just the name of the file
openFileDialog.FileName returns the full path to the file

I need to get folder path and a file name. I will create any type of file with the file name in the folder location. If a file with the user define name already exist need to overwrite the file.
Anyone can give any idea. How can do this in c# technology.
SaveFileDialog have been used. But it hasn't the overwrite option.
If the file already have exist.Prompted message:
You can use a OpenFileDialog with the option CheckFileExists set to false and use this instead of the SaveFileDialog.
Then you get a filepath and now can check the way you've already done it.
Make sure the property OverwritePromt is set to true. This is the default value, but if it is set to false, the user will not be warned about overwriting an existing file.
SaveFileDialog dialog = new SaveFileDialog();
// If the user selects an existing file, this will promt a warning about overwriting the existing file.
dialog.OverwritePrompt = true;
var result = dialog.ShowDialog();
if (result.HasValue && result.Value == true)
{
// Save the file...
}
I'm using C# windows application .
I want to save files in my local system.
I used Open File dialog to attach the files.
Here the text inside the file is copying,I want the file itself to get copied with a new name.But what I am really looking for is , it should just save the file automatically and not show the SaveDialog Box?
How it can be done in windows application.Can anybody help me please?
The code is shown below:
private string GetFileName()
{
OpenFileDialog op1 = new OpenFileDialog();
DialogResult result = op1.ShowDialog();
if (result == DialogResult.OK) // Test result.
{
txtEn.Text = op1.FileName;
FileName = op1.FileName;
//MessageBox.Show(FileName);
File.Copy(op1.FileName, #"D:\Backup\");
}
return FileName;
}
SQL Server 2012 seems unrelated to your question. Provided that you have proper access rights to the target directory, then in order to automate the procedure (as per your question) you don't need to use the OpenFileDialog; just a single line should suffice the goal:
//Overwriting a file of the same name is not allowed
File.Copy(FileName, #"D:\Backup\" + FileName)
or
//Overwriting a file of the same name is allowed
File.Copy(FileName, #"D:\Backup\" + FileName, true)
You can also apply some additional logic pertinent to backup file naming (upon necessity).
Hope this may help. Best regards,
Are you trying to copy a file from some x location on your file system to y location (in your case D:\Backup folder) in the file system? If that is the requirement here, I see that you are using the FileName property of OpenFileDialog which gets the File path. This you are appending to D:\Backup. You should instead use the Path.GetFileName property to first extract the file name with extension and then append it to the new folder path
File.Copy(fileName, #"D:\Backup\" + Path.GetFileName(fileName));
I have some data and I would like to export it to excel. I did all the code, and everything is working fine, Now I want to save that excel file to the hard drive. I could do that too. but my problem is that I couldn't know how to allow the customer to set his/her own file name.
What I have tried:
FolderBrowserDialog brwsr = new FolderBrowserDialog();
//Check to see if the user clicked the cancel button
if (brwsr.ShowDialog() == DialogResult.Cancel)
return;
else
{
string newDirectoryPath = brwsr.SelectedPath;
//Do whatever with the new path
}
the problem of that method is it is just allows the users to select the folder that the want the file to be saved to. I want to all the user to specifiy the path and the file name.
Any idea to help pleaes?
many thanks
You need to use a SaveFileDialog instead. This let's the user specify a path + filename. Check this out for more info: SaveFileDialog on MSDN
SaveFileDialog is pretty similar to FolderBrowserDialog, so you can almost replace the existing code you already have ;)
Specify File Type (EDIT)
Have a look a the Filter property.
Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*
How to get the full path string from a SaveFileDialog? SaveFileDialog.FileName only gives me the filename with extension. I have looked into SaveFileDialog on MSDN, but I don't see any property does that.
I need to return "C:\Folder1\subFolder2\File004.sdf" not just "File004.sf"
"Gets or sets a string containing the full path of the file selected in a file dialog." is what the MSDN article you linked says for FileName property. Plus, FileName has always given me the full file path.
What I basically do is more or less
SaveFileDialog x = new SaveFileDialog();
if (x.ShowDialog() == DialogResult.OK)
{
//Use here x.FileName
}
and it always returned the full path. Are you sure you don't see the absolute path?
I think you might be using the wrong dll - win32 instead of WinForms. Had the same issue today.
You must catch it after you press "Ok", not before.
In a WPF app I need to make it possible for a user to pick a file by the standard Open File Dialog and save it to the predefined folder (user doesn't know where it is) right after the user click OK button on Open File Dialog. Something like of importing a file to the application. I do it in the following way:
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog();
dlg.Filter = "Text documents (.txt)|*.txt";
Nullable<bool> result = dlg.ShowDialog();
if (result == true)
{
string filename = dlg.SafeFileName;
System.IO.File.Copy(filename, #"E:\TestFolder\" + filename);
MessageBox.Show("File " + filename + " saved");
}
Is there a standard way to check if the file already exists before trying to save it and if it is really saved after saving it?
Look at System.File.Exists that should be able to tell you what you need to know.
The System.IO.File.Exists method returns true if a file at the given path exists, so you could use it to check both before and after your copy operation.
Use the SaveFileDialog (Microsoft.Win32). If you try to save over a file that already exists it will prompt you to make sure you want to save over that file. This doesn'y actually save it though, all it will do is provide the name and location of the file you want to create/save over. After you use the SaveFileDialog to select the file you then need to do the work of saving the file.
