Membership Generate Password alphanumeric only password?

Question

How can I use Membership.GeneratePassword to return a password that ONLY contains alpha or numeric characters? The default method will only guarantee a minimum and not a max

Answer 1

There is similar approach with breigo's solution. Maybe this is not so effective but so clear and short

string GeneratePassword(int length)
{
     var password = "";
     while (password.Length < length)
     {
          password += string.Concat(Membership.GeneratePassword(1, 0).Where(char.IsLetterOrDigit));
     }
     return password;
}
