C# code to save text from listbox to a text file -- SOLVED--

[freebird73717]

Hello.

I am in the process of writing a gui and am stuck on one piece of code. I have a listbox that contains text. I would like to click my save button and be able to save the contents of the listbox to a text file. So far I can click "save" and give the file I'm "saving" a name and that goes okay...but nothing really happens. I know I need to use a function like streamreader and or streamwriter I'm just at a loss how. Any body have any clues?

Here is the code I have now

void Button3Click(object sender, EventArgs e)
		{
			if (saveFileDialog2.ShowDialog() == DialogResult.OK);
		}

Any help would be appreciated.

Here's some code from an app that writes to a file:

StreamWriter log = new StreamWriter(logfile.FullName, true);
log.WriteLine(DateTime.Now + "\t Could not find the ini file - " + aName + Environment.NewLine);

The streamwriter constructor take a path to your file, and the true/false parameter is for appending/overwriting. In my code, the logfile is a FileInfo object, and the fullname property contains the fully qualified path/filename. The writeline sends the line of text to the file. Remember to close the file when finished writing.


Hope this helps. Let me know if you need more...

Thanks for the reply tekkieman. I tried your code but got errors. However I did come up with some code that works.

void Button3Click(object sender, EventArgs e)
		{
		if (saveFileDialog2.ShowDialog() == DialogResult.OK)	
  {
    System.IO.StreamWriter sw = new System.IO.StreamWriter(saveFileDialog2.FileName);
 
    foreach (object item in listBox1.Items)
    
    	sw.WriteLine(item.ToString());
 
      sw.Close();
		};}

I do appreciate the help though.

My gui is finished now. It is a batch processing gui for HCenc. I started a new thread on it Here. If you get the chance you might check it out and give me some feedback. It is my first attempt at writing a gui.
