Question

所以我有一个名为'Inlogpoging'的登录尝试循环。 3次后，它需要给你“登录限制”的消息。但是我最终在剧本中遇到错误，这有什么不对？

static void Main(string[] args)
{
    for (int inlogpoging = 0; inlogpoging < 3; inlogpoging++)
    {
        Console.WriteLine("Status: " + status.Onaangemeld);
        Console.Write("Gebruikersnaam:");
        string Naam = Console.ReadLine();

        Console.Write("Wachtwoord:");
        string Wachtwoord = Console.ReadLine();

        if (Naam == "administrator" && Wachtwoord == "SHARPSOUND")
        {
            Console.Clear();
            Console.WriteLine("Status: " + status.Ingelogd);
            Console.WriteLine("Welkom bij SoundSharp {0}!", Naam);
            Console.ReadLine();
            break;
        }

        Console.Clear();
        Console.WriteLine("Helaas, gebruikersnaam of wachtwoord niet correct.");
    }

    if (int inlogpoging == 3); //Right here <--
    {
        Console.Clear();
        Console.WriteLine("Login limited.");
    }
}

Answer 1

if附近有语法错误; if内不允许声明，这些声明用于评估条件。并且无需使用;终止它们，以下代码可以帮助您：

int inlogpoging = 0;
for (; inlogpoging < 3; inlogpoging++)
    {
        // do the operations here
    }
// change the if as below
if (inlogpoging == 3) 
    {
       Console.Clear();
       Console.WriteLine("Login limited.");
    }

我认为你的代码没有做你想要的。考虑下面的代码，检查评论：

static void Main(string[] args)
      {

        int inlogpoging = 0;//initialize int counter
        while(inlogpoging<3)
        {
          if (inlogpoging == 3) //if equal to 3 then stop loguin process
          {
            Console.Clear();
            Console.WriteLine("Login limited.");
          }
          else {//if not 3 then process loguin
            Console.WriteLine("Status: " + status.Onaangemeld);
            Console.Write("Gebruikersnaam:");
            string Naam = Console.ReadLine();

            Console.Write("Wachtwoord:");
            string Wachtwoord = Console.ReadLine();

           //at this point increment counter
            inlogpoging++;

            if (Naam == "administrator" && Wachtwoord == "SHARPSOUND")
            {
                Console.Clear();
                Console.WriteLine("Status: " + status.Ingelogd);
                Console.WriteLine("Welkom bij SoundSharp {0}!", Naam);
                Console.ReadLine();

                Console.Clear();
                Console.WriteLine("Helaas, gebruikersnaam of wachtwoord niet     correct.");


               //need a exit point
               return 0;
            }
        }
      }
    }

即使我把它公之于众，也无法调用int
