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.
