  Some example strings that would match your expression are all exactly 25 characters long, containing any combination of letters (A-Z) and numbers (0-9), except for the characters I, O, and Z.

  Hi Nasha,
  
  Thanks for you help, but when I run a regex test on the 2nd string you gave me, it doesn't work. I tried it on multiple regex testing sites...

  Hi,

  The below code works just fine for me

  private void button2_Click(object sender, EventArgs e)

  {

  System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex("^([A-H]|[J-N]|[P-Y]|[0-9]){25}$");

  MessageBox.Show(regex.IsMatch("ABCDEFGHJKLMNPQRSTUVWXY0123456789").ToString());

  MessageBox.Show(regex.IsMatch("ABCDEJKNPQSTUXY0123456789").ToString());

  }

  Test this using C# winform.

  In case of any queries get back.

  Regards,

  Nasha

  Hi there,

  System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex("^([A-H]|[J-N]|[P-Y]|[0-9]){25}$");

  MessageBox.Show(regex.IsMatch("ABCDEFGHJKLMNPQRSTUVWXY0123456789").ToString());

  MessageBox.Show(regex.IsMatch("ABCDEJKNPQSTUXY0123456789").ToString());

  The first line of the code above is the set of characters which are valid for this regular expression which takes characters from AtoH,JtoN,PtoY and numbers from 0to9 and the length of the string should be 25 characters.

  The second line of the code is a valid regular expression ;)

  Hope this helps.

  Get back in case of any queries.

  Regards,

  Nasha
