ListBox Manager in C#

Write to File from ListBox

Write the code for writefile as shown below. For now, you can call this from mnuSave.

private void writefile()
{
   // Filename is "Untitled" initially, on mnuNew and mnuSaveAs.
   if (currentFileName == "Untitled")
   {
      saveFileDialog1.Filter = "Text Files|*.txt|All Files|*.*";
      saveFileDialog1.ShowDialog();
      // Filename is "" if cancel selected. 
      if (saveFileDialog1.FileName != "")
      {
          currentFileName = saveFileDialog1.FileName;
          Text = currentFileName;
       }
    }  
    if (currentFileName!="Untitled")
    {
       using (System.IO.StreamWriter file =
          new System.IO.StreamWriter(currentFileName))
       {
          // Write each item in list box to file.
          foreach (string item in lstData.Items)
          {
             file.WriteLine(item);
          }
          file.Close();
          // We just saved, so no changes since last save.
          changed = false;
       }
   }
}

To Do: Call writefile from mnuSave. Make sure this works before proceeding.

That's all! Congratulations on completing all of the lessons in csharp!
