无法将整个列表打印到控制台 [英] Unable to print whole list to console

问题描述

在控制台上打印列表时，请始终收到以下消息.

Keep getting the following message when printing a list on console.

System.Collections.Generic.List`1[System.Int32]

这是控制台代码.它旨在生成给定长度的斐波那契序列.我尝试使用ToString()方法，但这也不起作用.我已经用Java构建了算法，所以我知道这个问题从根本上讲是C#问题.如果我单独打印列表元素，但无法打印整个列表，则此问题已解决.

This is the console code. It is designed to generate a Fibonacci sequence of a given length. I have tried using the ToString() method, but that doesn't work either. I have built the algorithm in Java so i know that the issue, is fundamentally a C# problem. The issue is resolved if print i print the list elements individually, but i can't print the whole list.

class Program
{
    public static void Main(string[] args)
    {
        Fibonacci fibo = new Fibonacci();


        Console.WriteLine(fibo.getSequence(9));

        Console.ReadLine();
    }
}

class Fibonacci
{

    public List<int> getSequence(int length)
    {
        List<int> results = new List<int>();

        results.Add(1);
        results.Add(1);

        int counter = 0;

        while (counter != length - 2)
        {
            int num1 = results[results.Count - 1];
            int num2 = results[results.Count - 2];

            results.Add(num1 + num2);
            counter++;
        }

        return results;
    }
}

推荐答案

您正尝试直接将对象打印到控制台，尝试遍历列表并在返回的任何位置打印它们.

You are trying to print the object directly to console try iterating over list and print them wherever returned.

for (var item in returned) 
   Console.WriteLine(item)

(如果使用自定义类型).请记住，您已经定义了它的to字符串方法.

if using a custom Type. keep in mind that you have defined its to string method.
