c# - 类、结构或接口(interface)成员声明中的标记无效

Question

我的代码有问题:

using System;
using System.Threading;

namespace popo
{
    public class Human
    {
        public static void Main()
        {
            Console.Write("Login: ");
            public string LogInput = Console.Read();
            if(LogInput=="ADMIN")
            {
                System.Console.Write("Password: ");
                public string PassInput = Console.Read();
                if(PassInput == "ADMIN")
                {
                    System.Console.Write("L");
                    Thread.Sleep(1000);
                    System.Console.Write("O");
                    Thread.Sleep(1000);
                    System.Console.Write("G");
                    Thread.Sleep(1000);
                    System.Console.Write("G");
                    Thread.Sleep(1000);
                    System.Console.Write("E");
                    Thread.Sleep(1000);
                    System.Console.Write("D");
                }
            }
        }
    }
}

当我试图编译它时，编译器说:

Mm.cs(10,38): error CS1513: } expected
Mm.cs(12,13): error CS1519: Invalid token 'if' in class, struct, or interface member declaration
Mm.cs(12,24): error CS1519: Invalid token '==' in class, struct, or interface member declaration
Mm.cs(14,37): error CS1519: Invalid token '(' in class, struct, or interface member declaration

在您的Main() 内函数，局部变量LogInput和 PassInput必须在没有 public 的情况下声明关键词。另外，替换 Console.Read()通过 Console.ReadLine() .因此，您的 Main()应该是这样的:

public static void Main()
{
    Console.Write("Login: ");
    string LogInput = Console.ReadLine();
    if(LogInput=="ADMIN")
    {
        System.Console.Write("Password: ");
        string PassInput = Console.ReadLine();
        if(PassInput == "ADMIN")
        {
           // further as you had it...
        }
    }
}
