I have a textbox that the user can only enter characters in a certain order into to enable a button. I would like it to be like this: (N = 'number' and L = 'letter')
IF textBox1 contains character order of (NNNNNLNN-NNNL-NNLL-NLNN-LNNLLLNNLLLL)
    { button1.Enabled = true; }
ELSE { button1.Enabled = false; }

So I want to enable the button if the order and amount of letters, numbers and dashes is in the correct combination of NNNNNLNN-NNNL-NNLL-NLNN-LNNLLLNNLLLL. How would I do this in C#. Thanks

I recommend using Regex to determine this.  See this[^] awesome Regex tutorial and this[^] page to test your Regex expression.
