我需要检查包含以下4个中的3个的密码:
密码长度必须介于6到20个字符之间.我目前有这个:
public void ChangePassword(string password)
{
Regex regex1 = new Regex("^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z]){6,20}$");
Regex regex2 = new Regex("^(?=.*[0-9])(?=.*[a-z])(?=.*?[#?!@$%^&*-]){6,20}$");
Regex regex3 = new Regex("^(?=.*[0-9])(?=.*[A-Z])(?=.*?[#?!@$%^&*-]){6,20}$");
Regex regex4 = new Regex("^(?=.*[a-z])(?=.*[A-Z])(?=.*?[#?!@$%^&*-]){6,20}$");
Regex regex5 = new Regex("^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*?[#?!@$%^&*-]){6,20}$");
Match match1 = regex1.Match(password);
Match match2 = regex2.Match(password);
Match match3 = regex3.Match(password);
Match match4 = regex4.Match(password);
Match match5 = regex5.Match(password);
if (match1.Success || match2.Success || match3.Success ||
match4.Success || match5.Success)
{
Password = password;
}
else
{
throw new PasswordNotGoodException();
}
}

但是,这根本不匹配.这是一个学校项目,所以我真的可以使用一些帮助.
