Save text from rich text box with C#

Question

This question has been answered. I've improved the code a bit (at least I think so). It now reminds of the aceepted answer to the question Open file in rich text box with C#. If I haven't made any mistakes (which I may have), the code should save a file with text from the rich text box rtfMain. The default file extension is .txt. You can also use the file extension .rtf.

private void menuFileSave_Click(object sender, EventArgs e) 
{ 
// Create a new SaveFileDialog object 
using (SaveFileDialog dlgSave = new SaveFileDialog())
  try
  {
    // Default file extension
    dlgSave.DefaultExt = "txt"; 
    // SaveFileDialog title
    dlgSave.Title = "Save File As";
    // Available file extensions
    dlgSave.Filter = "Text Files (*.txt)|*.txt|RTF Files (*.rtf)|*.rtf"; 
    // Show SaveFileDialog box and save file
    if (dlgSave.ShowDialog() == DialogResult.OK) 
    { 
      // Save as .txt file
      if (Path.GetExtension(dlgSave.FileName) == ".txt")
      {
        rtfMain.SaveFile(dlgSave.FileName, RichTextBoxStreamType.PlainText);
      }
      // Save as .rtf file
      if (Path.GetExtension(dlgSave.FileName) == ".rtf")
      {
        rtfMain.SaveFile(dlgSave.FileName, RichTextBoxStreamType.PlainText);
      }
    }
    catch (Exception errorMsg)
    {
      MessageBox.Show(errorMsg.Message);
    }
  }
}
private void rtfMain_TextChanged(object sender, EventArgs e)
{
}

Update: I have improved the code even further (at least I think so). The main difference is that you now have more control over the file encoding. This is the code I'm using right now:

private void fileSave_Click(object sender, EventArgs e)
{
  // Text from the rich textbox rtfMain
  string str = rtfMain.Text;
  // Create a new SaveFileDialog object
  using (SaveFileDialog dlgSave = new SaveFileDialog())
  try
  {
    // Available file extensions
    dlgSave.Filter = "All Files (*.*)|*.*";
    // SaveFileDialog title
    dlgSave.Title = "Save";
    // Show SaveFileDialog
    if (dlgSave.ShowDialog() == DialogResult.OK && dlgSave.FileName.Length > 0)
    {
      // Save file as utf8 without byte order mark (BOM)
      // ref: http://msdn.microsoft.com/en-us/library/s064f8w2.aspx
      UTF8Encoding utf8 = new UTF8Encoding();
      StreamWriter sw = new StreamWriter(dlgSave.FileName, false, utf8);
      sw.Write(str);
      sw.Close();
    }
  }
  catch (Exception errorMsg)
  {
    MessageBox.Show(errorMsg.Message);
  } 
}

You should use the using statement. – Dominiquedominium

According to msdn.microsoft.com/en-us/library/yh598w02(VS.80).aspx, "it is usually best to release limited resources such as file handles and network connections as quickly as possible" and "the using statement allows the programmer to specify when objects that use resources should release them". Is this the main reason for using the using statement? – Inadvertence

Yup, this is old, but your code helped me – Goddord

Answer 1

Like this:

 rtfMain.SaveFile(dlgSave.FileName);

SLaks way is the easiest. But to get your own code running, you could add writeMe.Flush() after writing to it. – Violation

Thank you! Where do I put your code? I tried every position I could think of, but nothing worked. – Inadvertence

No. I'm a C# beginner. I'm just trying to make some basic code work and continue from there. Having a couple of years experience of PHP, that seems to remind a lot of C#, I think that's a good idea. Earlier today, I managed to get an open file dialog to work. Now I'm trying to do the same with a save file dialog. – Inadvertence

Put it after if (dlgSave.ShowDialog() == DialogResult.OK) and remove the rest of the method, then learn C#. – Dominiquedominium

Then you should accept this answer by clicking the hollow check. – Dominiquedominium

I know. I forgot to do it. Sorry about that. It's fixed now. – Inadvertence

Answer 2

Your code here saves .doc files formatted. When I use it to save .docx files it does save it but when I try to open the saved file using Microsoft Word, An error message is displayed.
