我试图创建一个银行场景，其中工人输入客户ID和客户的信息显示，我已经与类无法访问的问题，现在它似乎无法找到它在所有。

public class Program
{
    public class customer1
    {
        string name = "Akan Udoh";
        int id = 101;
        String type = "Current";
    }
    public class customer2
    {
        string name = "Clara Udoh";
        int id = 102;
        string type = "Savings";
    }
    public class customer3
    {
        string name = "jane doe";
        int id = 103;
        string type = "Fixed deposit";
    }
    static void Main(string[] args)
    {
        Console.WriteLine("Enter Customer id");
        int id = Convert.ToInt32(Console.ReadLine());
        switch (id)
        {
            case 101:
                customer1 customer1 = new customer1();
                Console.WriteLine(customer1);
                Console.WriteLine(customer1);
                Console.WriteLine(customer1);
                break;
            case 102:
                customer2 customer2 = new customer2();
                Console.WriteLine(customer2);
                Console.WriteLine(customer2);
                Console.WriteLine(customer2);
                break;
            case 103:
                customer3 customer3 = new customer3();
                Console.WriteLine(customer3);
                Console.WriteLine(customer3);
                Console.WriteLine(customer3);
        }
    }
}

正如其他人在评论中提到的那样，您可能不想为每个客户创建一个类，而是希望创建一个具有许多示例的单个Customer类。
我相信你想实现这样的目标：

public class Program
{
    public class Customer
    {
        public string Name;
        public int Id;
        public string Type;
    }
    static void Main(string[] args)
    {
        var customers = new Customer[]
        {
            new Customer
            {
                Name = "Akan Udoh",
                Id = 101,
                Type = "Current"
            },
            new Customer
            {
                Name = "Clara Udoh",
                Id = 102,
                Type = "Savings"
            },
            new Customer
            {
                Name = "jane doe",
                Id = 103,
                Type = "Fixed deposit"
            },
        };
        // As an alternative, you could add all customers to a dictionary for a faster search
        // var customerDictionary = new Dictionary<int, Customer>();
        // foreach (Customer cust in customers)
        //     customerDictionary.Add(cust.Id, cust);
        Console.WriteLine("Enter Customer id");
        var id = Convert.ToInt32(Console.ReadLine());
        var customer = customers.Where(x => x.Id == id).FirstOrDefault();
        // If you choose a dictionary, you can find it like this instead of the above Linq query
        // var customer = customerDictionary[id];
        Console.WriteLine(customer.Name);
        Console.WriteLine(customer.Id);
        Console.WriteLine(customer.Type);
    }
}
