Question

我有3个类和一个结构，我正在尝试使用访问器打印出总数。程序打印总数为的消息。没有打印结果。试图解决这个问题？

主：

class MainClass
{
    static void Main(string[] args)
    {
        ArrayList list = new ArrayList();

        list.Add("1. option one");
        list.Add("2. option two");
        list.Add("3. option three");
        list.Add("4. option four");
        list.Add("5. option five");

        Console.WriteLine("1. option one");
        Console.WriteLine("2. option two");
        Console.WriteLine("3. option three");
        Console.WriteLine("4. option four");
        Console.WriteLine("5. option five");
        Console.WriteLine(" Pick  3 options ");

        UserInput usi = new UserInput();
        usi.Get();

        Console.WriteLine(" You Picked ");
        usi.print();

        Console.ReadLine();
    }
}

计划类：

class Program 
{
    private int A, B;
    public void GetAB()
    {
        Console.WriteLine("Enter A: ");
        A = int.Parse(Console.ReadLine());
        if ((A <= 0) || (A >= 6))
          //  Console.WriteLine("good");
            throw new ArgumentOutOfRangeException("Number must be between 1-5");
        Console.WriteLine("Enter B: ");
        B = int.Parse(Console.ReadLine());
        if ((B <= 0) ||(B >=6))
             throw new ArgumentOutOfRangeException("Number must be between 1-5");
    }
    public void PrintAB()
    {
        Console.WriteLine("A = {0}\tb = {1}\t", A, B);
    }
}

用户输入：

class UserInput : Program
{
    int C;

    public void Get()
    {
        try
        {
            Console.WriteLine("Valid entries are 1-5");
            GetAB();
            Console.Write("Enter C: ");
            C = int.Parse((Console.ReadLine()));
            if ((C <= 0) || (C >= 6))
                throw new ArgumentOutOfRangeException("Number must be between 1-5");
        }
        catch (ArgumentOutOfRangeException ex)
        {
            // Show the user that 7 cannot be divided by 2.
            Console.WriteLine("Error: {0}", ex.Message);
            Console.WriteLine("Please try again ");

            System.Environment.Exit(1);
        }
    }

    public int A
    { get; set; }
    public int B
    { get; set; }

    public void total()
    {
        int total = (A + B + C);
        Console.WriteLine(" Total is ", total);
    }

    public void print()
    {
        PrintAB();
        Console.WriteLine("C = {0}", C);
        total();
    }
}

总：

struct Total
{
    public int total { get; set; }
}

Answer 1

你这样做：

Console.WriteLine("Total is : ", total);
// In userInput.total()

应该改为：

Console.WriteLine("Total is : " + total);

OR

Console.WriteLine("Total is : {0}", total);
