Answer 1

The normal way to do that would be ^.$.

This means only one character between the start and end anchors.

Feel free to change . to any other limitation to suit your purposes.

And keep in mind, there may be other ways to do what you want. For example, if it's a WPF TextBox, you can set properties on the text box itself that will restrict lengths without you having to worry about regexes.
