c# - 两个字符串变量与返回 bool 值的私有(private)字典进行比较c#

Question

我试图创建两个名为用户名和密码的字符串变量，并返回一个名为“authentiated”的 bool 值。我试图将用户名和密码字符串与私有(private)字典的内容进行比较。如果用户名和密码匹配，我希望将 bool 值设置为 true。然而，我是 C# 新手，真的不知道该去哪里。任何帮助，将不胜感激。以下是我已经拥有的。 `

private Dictionary<string, string> dictionary = new Dictionary<string, string>();

        public Authenticator()
        {
            dictionary.Add("username1", "password1");
            dictionary.Add("username2", "password2");
            dictionary.Add("username3", "password3");
            dictionary.Add("username4", "password4");
            dictionary.Add("username5", "password5");
        }


        public Boolean Authenticate(Boolean authenticated)
        {
            //get user input 
            Console.WriteLine("Please enter a username");
            string inputUsername = Console.ReadLine();

          var auth1 = from entry in dictionary
                             where entry.Key == " ";

            Console.WriteLine("Please enter your password");
            string inputPassword = Console.ReadLine();

            var auth2 = from entry in dictionary
                        where entry.Value == " ";
                         `

试试这个:

    public bool Authenticate()
    {
        Console.WriteLine("Please enter a username");
        string inputUsername = Console.ReadLine();
        Console.WriteLine("Please enter your password");
        string inputPassword = Console.ReadLine();
        return dictionary.ContainsKey(inputUsername) && dictionary[inputUsername] == inputPassword;
    }
