Try this: using System; using System.Text.RegularExpressions; class Program { static void Main() { string[] names = {/John/ /John Doe/ /John-Doe/ /John_Doe//John Doe's/ /John Frederick Doe/ /John Doe 2/ //John /John / /John>Doe/}; string regExp = @^/\w+((\s+|-|')\w+)*/$; foreach(string name in names) { Console.WriteLine({0} -> {1} name Regex.IsMatch(name regExp)); } Console.ReadKey(); } } The output is: /John/ -> True /John Doe/ -> True /John-Doe/ -> True /John_Doe/ -> True /John Doe's/ -> True /John Frederick Doe/ -> True /John Doe 2/ -> True //John -> False /John / -> False /John>Doe/ -> False

/[a-zA-Z]+(([\'\.\-][a-zA-Z])?[a-zA-Z]*)/ it work for /John/ but does not work for /John Doe/. so please help for both scenario. Thanks

The following regular expression will validate text consisting of a single alphabetic word enclosed within forward slashes: string regExp1 = ^/[a-zA-Z]+/$; and this one will do the same thing except that a word can also now include digits and the underscore character: string regExp2 = @^/\w+/$; The corresponding expressions for multiple consecutive words would be: string regExp3 = ^(/[a-zA-Z]+)+/$; string regExp4 = @^(/\w+)+/$;
