See below or play around with it in Dotnetfiddle
// By default, all characters available for use and a length of 16
// Will return a random password with the default settings
PasswordGenerator pwdGen = new PasswordGenerator();
string password = pwdGen.Next();// Same as above but you can set the length. Must be between 8 and 128
// Will return a password which is 32 characters long
PasswordGenerator pwdGen = new PasswordGenerator(32);
string password = pwdGen.Next();// Same as above but you can set the length. Must be between 8 and 128
// Will return a password which only contains lowercase and uppercase characters and is 21 characters long.
PasswordGenerator pwdGen = new PasswordGenerator(includeLowercase: true, includeUppercase: true, includeNumeric: false, includeSpecial: false, passwordLength: 21);
string password = pwdGen.Next();// You can build up your reqirements by adding things to the end, like .AddNumeric()
// This will return a password which is just numbers and has a default length of 16
PasswordGenerator pwdGen = new PasswordGenerator().IncludeNumeric();
string password = pwdGen.Next();// As above, here is how to get lower, upper and special characters using this approach
PasswordGenerator pwdGen = new PasswordGenerator().IncludeLowercase().IncludeUppercase().IncludeSpecial();
string password = pwdGen.Next();// This is the same as the above, but with a length of 128
PasswordGenerator pwdGen = new PasswordGenerator(128).IncludeLowercase().IncludeUppercase().IncludeSpecial();
string password = pwdGen.Next();// This is the same as the above, but with passes the length in using the method RequiredLength()
PasswordGenerator pwdGen = new PasswordGenerator().IncludeLowercase().IncludeUppercase().IncludeSpecial().RequiredLength(128);
string password = pwdGen.Next();
