Question

如果我输入正确的密码，我怎么能告诉程序才能访问？谢谢。

namespace Password
{
  class Program
  {
    static void Main(string[] args)
    {
        Console.WriteLine("Please enter password:");
        Console.ReadLine();



        string Password = "Test";
        bool PassWordMatch;

        PassWordMatch = Password == "Test";

        if (PassWordMatch)
        {

            Console.WriteLine(" Password Match. Access Granted");

        }
        else
        {
           Console.WriteLine("Password doesn't match! Access denied.");

        }

    }
}

}

您可以使用Console.ReadLine方法返回用户输入的值，您可以将其存储在相应的变量中：

namespace Password 
{ 
    class Program 
    { 
        static void Main(string[] args) 
        { 
            Console.WriteLine("Please enter password:"); 
            string password = Console.ReadLine();
            bool passWordMatch;

            passWordMatch = password == "Test";

            if (passWordMatch)
            {
                Console.WriteLine(" Password Match. Access Granted");
            }
            else
            {
                Console.WriteLine("Password doesn't match! Access denied.");
            }
        }
    }
}

你几乎就在那里。

Console.ReadLine()方法读取标准输入strem并将其返回为string。您只需要确定此方法返回新字符串的内容，并将其与测试密码进行比较。

Console.WriteLine("Please enter password:");
string input = Console.ReadLine();

bool PassWordMatch = input == "Test";
if(PassWordMatch)
   Console.WriteLine(" Password Match. Access Granted");
else
   Console.WriteLine("Password doesn't match! Access denied.");

当然，这不是应用程序安全性的好方法。

您尚未将读取字符串分配给变量，因此无法进行比较。

Console.ReadLine()函数可用于从输入流中读取下一行字符，如果没有更多行可用，则返回null。

你可以这样做：

namespace Password 
{ 
    class Program 
    { 
        static void Main(string[] args) 
        { 
            Console.WriteLine("Please enter password:"); 
            string password = Console.ReadLine(); //Assign user-entered password 
            bool passWordMatch;

            passWordMatch = password == "Test";

            if (passWordMatch)
            {
                Console.WriteLine(" Password Match. Access Granted");
            }
            else
            {
                Console.WriteLine("Password doesn't match! Access denied.");
            }
        }
    }
}
