Question

我正在试图弄清楚如何使用具有多个变量的对象填充数组。我需要的是创建一个数组，而不是一个列表（我正在尝试学习数组），并用5个不同的bourbons填充它。是否可以填充数组并将名称，年龄，酒厂存储在一个索引中？例如，

如果我调用了索引0，它将显示：

Name: Black Maple Hill
Distillery: CVI Brands, Inc
Age: 8 years

到目前为止我有这个，其中波本威士忌是来自威士忌的派生类，并在主类中调用一个方法来提示用户输入。

class Bourbon : Whiskey
{
    private Bourbon[] bBottles = new Bourbon[5];

    public void bourbon(string name, string distillery, int age)
    {
        Name = name;
        Distillery = distillery;
        Age = age;
     }

    public void PopulateBottles()
    {
         Console.WriteLine("Please enter the information for 5 bourbons:");
         for (int runs = 0; runs < 5; runs ++)
         {

         }
     }
}

Answer 1

在您的代码中，您尚未定义在for循环中使用的value变量。您可以创建该类的新实例，然后将它们存储在数组中：

public void PopulateBottles()
{
    Console.WriteLine("Please enter the information for 5 bourbons:");
    for (int runs = 0; runs < 5; runs ++)
    {
        Console.WriteLine("Name:");
        var name = Console.ReadLine();
        Console.WriteLine("Distillery:");
        var distillery = Console.ReadLine();
        Console.WriteLine("Age:");
        var age = int.Parse(Console.ReadLine());
        var bourbon = new Bourbon(name, distillery, age);
        bBottles[runs] = bourbon;
    }
}

还要确保已正确定义Bourbon类构造函数：

public Bourbon(string name, string distillery, int age)
{
    Name = name;
    Distillery = distillery;
    Age = age;
}

Answer 2

@Jonathan。是的，根据我的解释，这是可能的。您可以尝试使用索引器。

Class Bourbon : Whiskey {
 public Bourbon this[int index]
 {
     get {
         return bBottles[index];
     }
     set {
         bBottles[index] = value;
     }  
    }  
}

Answer 3

选中此需要创建属性和一个构造函数以满足您的要求。

class Bourbon
    {

        private Bourbon[] bBottles = new Bourbon[5];

        private string name;

        public string Name
        {
            get { return name; }
            set { name = value; }
        }
        private string distillery;

        public string Distillery
        {
            get { return distillery; }
            set { distillery = value; }
        }
        private int age;

        public int Age
        {
            get { return age; }
            set { age = value; }
        }

        public Bourbon(string name, string distillery, int age)
        {
            Name = name;
            Distillery = distillery;
            Age = age;
        }

        public void PopulateBottles()
        {
            Console.WriteLine("Please enter the information for 5 bourbons:");
            for (int runs = 0; runs < 5; runs++)
            {
                Console.WriteLine("Name:");
                var name = Console.ReadLine();
                Console.WriteLine("Distillery:");
                var distillery = Console.ReadLine();
                Console.WriteLine("Age:");
                var age = int.Parse(Console.ReadLine());
                var bourbon = new Bourbon(name, distillery, age);
                bBottles[runs] = bourbon;
            }
        }
    }
