Save file to specific folder in C# using SaveFileDialog - c#

I need to save a file using SaveFileDialog to a specific folder.
For example, say we want to save in "c:\MyNewFolder". If the folder doesn't exist, create it and save there, or only save there if the folder does exist.
String fileName="";
String date = DateTime.Now.Day+"-"+DateTime.Now.Month+"-"+DateTime.Now.Year;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.FileName = fileName;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
using (Stream s = File.Open(saveFileDialog1.FileName,FileMode.CreateNew))
using (StreamWriter sw = new StreamWriter(s))
{
sw.WriteLine(tbName.Text);
sw.WriteLine(tbSummary.Text);
}
}

You can look for
SaveFileDialog save = new SaveFileDialog();
save.InitialDirectory = "c:\\MyNewFolder";
save.RestoreDirectory = true;

string strPath="c:\MyNewFolder";
if (!Directory.Exists(strPath))
{
Directory.CreateDirectory(strPath);
}
else
{
//Continue your logic and append your file name
}

Save stream of savefiledialog in c#

In my wpf app I have an "Export" button that suppose to save some json file to chosen path.
I mean my question is how to write the file, let's say he has the path D:\somefile.json to the chosen location that the user chose from save dualog?
Here my code:
void Export_button_Click(object sender, RoutedEventArgs e)
{
Stream myStream;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "Json files (*.json)|*.json";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
// Code to write the stream goes here.
myStream.Close();
}
}
This should be something like:
Copy(StreamOf(D:\somefile.json),ChosenPath)
SaveFileDialog sf = new SaveFileDialog();
sf.Filter = "Json files (*.json)|*.json";
sf.FilterIndex = 2;
sf.RestoreDirectory = true;
if (sf.ShowDialog() == DialogResult.OK)
{
System.IO.File.Copy(#"D:\somefile.json", sf.FileName, true);
}
you can use File.copy
public static void Copy(
string sourceFileName,
string destFileName)

Overwriting a text file from RichTextBox

Now if you write the text and click on the save button, OpenFileDialog will appear. If you finish something in the same document and click on the save button again, you need to select the save location again. How to make that when saving the same file you do not need to create a new file each time, and just overwrite the current one? Sorry for my English.
private void buttonSave_Click(object sender, EventArgs e)
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Rich Text File | *.rtf";
if (sfd.ShowDialog() == DialogResult.OK)
{
richTextBox1.SaveFile(sfd.FileName);
}
else
{
}
}
It sure is, you just need to remember the last file path you saved and not display the dialog again the next time around; something like this should help:
void Main()
{
Save();
}
private string _filePath = "";
void Save()
{
var overwrite = false;
if (!string.IsNullOrEmpty(_filePath))
{
var res =
MessageBox.Show("Would you like to overwrite your last saved file?", "Overwrite?", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning, MessageBoxDefaultButton.Button1,
MessageBoxOptions.DefaultDesktopOnly, false);
if (res == DialogResult.Cancel) return;
if (res == DialogResult.No) overwrite = false;
if (res == DialogResult.Yes) overwrite = true;
}
if (!overwrite)
{
var sfd = new SaveFileDialog();
sfd.Filter = "Rich Text File|*.rtf";
var res = sfd.ShowDialog();
if (res != DialogResult.OK) return;
_filePath = sfd.FileName;
}
// do the richTextBox.SaveFile(_filePath) here.
}
In this example it:
CHECK IF FILE PATH ALREADY SET
IF NOT THEN
ASK USER IF THEY WANT TO OVERWRITE THE LAST FILE
IF CANCEL THEN DON'T SAVE
IF YES THEN SET OVERWRITE TO TRUE
IF NO THEN SET OVERWRITE TO FALSE
END IF
CHECK IF OVERWRITING
IF OVERWRITING THEN
SHOW SAVE FILE DIALOG
IF USER DIDN'T CLICK OK THEN DON'T SAVE
IF USER CLICKED OK, SET THE NEW FILE PATH TO USE
END IF
SAVE THE FILE USING THE NOW-REMEMBERED FILE PATH
Perhaps:
private void SaveButton_Click(object sender, EventArgs e)
{
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.InitialDirectory = #"C:\";
saveFileDialog1.Title = "Save text Files";
saveFileDialog1.CheckFileExists = true;
saveFileDialog1.CheckPathExists = true;
saveFileDialog1.DefaultExt = "txt";
saveFileDialog1.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
saveFileDialog1.FilterIndex = 2;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
textBox1.Text = saveFileDialog1.FileName;
}
}
Example from: http://www.c-sharpcorner.com/uploadfile/mahesh/savefiledialog-in-C-Sharp/
Might help some?
private string filePath = string.Empty;
private void SaveButton_Click(object sender, EventArgs e)
{
if (File.Exists(filePath))
{
byte[] buffer = Encoding.ASCII.GetBytes(richTextBox1.Text);
MemoryStream ms = new MemoryStream(buffer);
//write to file
FileStream file = new FileStream(filePath, FileMode.Create, FileAccess.Write);
ms.WriteTo(file);
file.Close();
ms.Close();
}
else
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Rich Text File | *.rtf";
sfd.OverwritePrompt = false;
if (sfd.ShowDialog() == DialogResult.OK)
{
richTextBox1.SaveFile(sfd.FileName);
filePath = sfd.FileName;
}
}
}
you can use sfd.OverwritePrompt = false; property to avoid prompt messagebox if file already exists, is this what you are looking for ?

C# Create txt file and save

I am trying to create a file and save text, but it's only creating file can anyone suggest what the problem is?
private void button2_Click(object sender, EventArgs e)
{
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "Text File|*.txt";
sfd.FileName = "Password";
sfd.Title = "Save Text File";
if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string path = sfd.FileName;
StreamWriter bw = new StreamWriter(File.Create(path));
bw.Write(randomstring);
bw.Dispose();
}
}
You need to call bw.Close() before calling bw.Dispose(). Per the API: "You must call Close to ensure that all data is correctly written out to the underlying stream." (http://msdn.microsoft.com/en-us/library/system.io.streamwriter.close(v=vs.110).aspx)
I'd actually change the code to:
using (StreamWriter bw = new StreamWriter(File.Create(path)))
{
bw.Write(randomstring);
bw.Close();
}
The using block will automatically call Dispose(), whether or not everything completes successfully.
Try and use File.WriteAllText instead
if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
//...
File.WriteAllText(path, randomstring);
}
bw.Write(randomstring);
bw.Dispose();
You write something, then dispose of the object entirely. Try:
bw.Write(randomstring);
bw.Close();
bw.Dispose();
Per the documentation, you need to call bw.Close() before you dispose of it. Also, you should use using to ensure that all IDisposables are properly disposed of.
if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string path = sfd.FileName;
using (var fs = File.Create(path))
using (StreamWriter bw = new StreamWriter(fs))
{
bw.Write(randomstring);
bw.Close();
}
}
Or just use File.WriteAllText:
if (sfd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string path = sfd.FileName;
File.WriteAllText(path, randomstring);
}

Saving a file in windows forms

I already could open the save file dialog, but when i run the program and tried to save it, it could, but the file is not there. WHy is that? Here is the code:
_saved = false;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "System File (*.pos) | *.pos";
saveFileDialog1.Title = "Save File As";
saveFileDialog1.ShowDialog();
if (_saved)
{
this.Text = "Database - " + saveFileDialog1.FileName + "";
_filename = saveFileDialog1.FileName;
}
else
{
this.Text = this.Text;
}
Thank you, I appreciate your help.
The FileSaveDialog only gives you the UI to choose the file, once the file was choosen by the user you will get the FileName and is now your responsibility to do whatever is necesary with the FileName, such as storing your data and save it.
You should implement the save action by yourself, here is an example.
if(sf.ShowDialog() == DialogResult.OK)
{
using(var fs = new FileStream(sf.FileName,FileMode.Create))
{
// get bytes from text you want to save
byte [] data =new UTF8Encoding().GetBytes(text);
fs.Write(data,0,data.Length);
fs.Flush();
}
}
sf is saveFileDialog1

Set the PDF file name in C#

I am generating a PDF file with C#. The title of the file is assigned automatic. I want to set the file name when I open the folderbrowserdialog . How can i do that?
DialogResult result = folderBrowserDialog1.ShowDialog();
if (result == DialogResult.OK)
{
string caminho = folderBrowserDialog1.SelectedPath;
var pasta2 = caminho.Replace(#"\", #"\\");
Document doc = new Document(PageSize.A4.Rotate(), 10, 10, 42, 35);
PdfWriter.GetInstance(doc, new FileStream(pasta2 + "\\Relatorio.pdf", FileMode.Append, FileAccess.Write));
Try Something Like, You have to use SaveFileDialog , For more information visit MSDN
SaveFileDialog dialog1 = new SaveFileDialog();
dialog1.Title = "Save file as...";
dialog1.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*";
dialog1.RestoreDirectory = true;
if (dialog1.ShowDialog() == DialogResult.OK)
{
MessageBox.Show(dialog1.FileName);
}
you use dialog1.FileName when creating your FileStream:
PdfWriter writertest = PdfWriter.GetInstance(doc, new FileStream(dialog1.FileName, FileMode.Create));
Hope it works for you.
You can't set the Filename in FolderBrowserDialog, you need to use SaveFileDialog. Try this sample code
saveFileDialog1.FileName = "Akshay.pdf";
saveFileDialog1.FileOk +=new CancelEventHandler(saveFileDialog1_FileOk);
saveFileDialog1.ShowDialog();
private void saveFileDialog1_FileOk(object sender, CancelEventArgs e)
{
// MessageBox.Show("Done");
// do the PDF Method here
}
