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

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+)+/$";
