Ensure that we add all of the required groups first If (length < 4) throw new ArgumentException("String length must be at least 4 characters") The generated string must be at least 4 characters so that we can add a single character from each group. numerals, and special characters (!, #, $, £, etc) Generated strings must contain at least 3 of the following character groups: uppercase letters, lowercase letters Private static string Generate(int length, int seed) / Generates a string of the specified length using the specified seed Return Generate(length, Environment.TickCount)

Public static string Generate(int length) / Generates a string of the specified length / Generates string of the minimum length Private const string m_SpecialChars = Public Methods Private const string m_NumericChars = "123456890" Private const string m_UppercaseChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" Private const string m_LowercaseChars = "abcdefghijklmnopqrstuvqxyz" Private static bool m_UseSpecialChars = false public static class RandomStringGenerator It's similar to JohnIdol's Typing Monkey, but has a little more flexibility in case you want generated strings to contain uppercase, lowercase, numeric or special characters. Here's a utility class I've got to generate random passwords. String randomStr = myMonkey.TypeAway(size) Then all you've got to do is: TypingMonkey myMonkey = new TypingMonkey() StringBuilder builder = new StringBuilder() Ĭh = legalCharacters

/ The Typing Monkey Generates a random string with the given length. Private const string legalCharacters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890" / If you try hard enough it will eventually type some Shakespeare. / The Typing monkey generates random strings - can't be static 'cause it's a monkey. Thank you.If you can convert this to VB.NET (which is trivial) I'd say you're good to go (if you can't, use this or any other tool for what's worth): ///
