  Hi,

  
  Just do the following steps…

   

  Put a text box on the form (optional:set its multi line property to true and dock fill).

   

  Write following code in Open menu

   

  OpenFileDialog opd = new OpenFileDialog();             if (DialogResult.OK==(opd.ShowDialog()))                 textBox1.Text = ReadFile(opd.FileName);

   

   

  Write following code in Save menu

   

  SaveFileDialog sfd = new SaveFileDialog();             if (DialogResult.OK==(sfd.ShowDialog()))                 SaveFile(sfd.FileName);

   

  Write following functions on the form to open and read file and return a string

   

  string ReadFile(string path)         {                         try             {                 StreamReader sr = new StreamReader(path);                 string data=sr.ReadToEnd();                 sr.Close();                 return data;                             }             catch (Exception exception)             {                 //handle error                 return "";                            }

   

   

  Write following function on the form to read text from text box and save to file

   

  void SaveFile(string path)         {                         try             {                   StreamWriter sw = new StreamWriter(path);                                 sw.Write(textBox1.Text);                 sw.Flush();                 }               catch (Exception ex)             {                 //error handling             }                             }

   

  Hope this help.

  I think you are looking for String.Split.

  Figured it out. Thanks for help, guys.

  Create an instance of the Open File Dialog and fill the properties. Then show the Dialog.

  OpenFileDialog openFiles = new OpenFileDialog ( );

  openFiles.InitialDirectory = "C:\Temp\";
  openFiles.Filter = "Text files (*.txt)|*.txt";
  openSsnKount.FilterIndex = 1;
  openSsnKount.RestoreDirectory = false;

  if ( openSsnKount.ShowDialog ( ) == DialogResult.Cancel )
  {
  openSsnKount.Dispose ( );
  }

  That's about it except what you want to do with the selected file.

  In Java, I used something called a 'StringTokenizer'.  Is there a substitute for this within C#   The file that i am reading contains the following: "one", "2", "three".  I need to get all three values out of line.  I am using ReadLine to take the line out of the file, but I need to seperate all 3 values.

  The String.Split is working great. However, lets say I have the following string: "one", "two", "three". How could I store each of these values into a seperate variable

  I currently have the following code:

  string line = sr.ReadLine();

  char[] seps = new char[]{','};

  foreach (string ss in line.Split(seps))

  {

  how would i make it so:

  string 1 = one
  string 2 = two
  string 3 = three

  }

  Thanks Again,
