It depends on what rules you're using for valid passwords but the following will give you an idea of how they can be generated in a simple case - password length 8 to 12 characters which can be any upper or lower case letters or digits. For illustration purposes I've used a console application: using System; using System.Text; class Test { // needs to be a field to get different answers each time program is run static Random rand = new Random(); static void Main() { // get 20 random passwords for(int i = 1; i { string password = GetRandomPassword(); Console.WriteLine(password); } Console.ReadKey(); } static string GetRandomPassword() { // get random length between 8 and 12 characters int len = rand.Next(8 13); /* now get 'len' random characters 0 - 25 represents a to z 26 - 51 represents A to Z 52 - 61 represents 0 to 9 */ var sb = new StringBuilder(len); for(int i = 1; i { int temp = rand.Next(0 62); char c; if (temp { c = (char)(temp + 97); } else if (temp { c = (char)(temp + 39); } else { c = (char)(temp - 4); } sb.Append(c); } return sb.ToString(); } }
