打印列表< object>在控制台C#中 [英] print list<object> in console c#

问题描述

当我尝试在c#中打印对象列表时，它无法打印我想要的内容，让我演示一下.

when i try to print a list of objects in c# it does not print what i want, let me demonstrate.

示例:

public class Classname
    {
        public string hello;
        public string world;

        
    }

namespace inloggning
{

    class Program
    {
        static void Main(string[] args)
        {
            List<object> listOfObjects = new List<object>();

            Classname example = new Classname();
            example.hello = "hello";
            example.world = "world";

            listOfObjects.Add(example);

            Console.WriteLine(listOfObjects[0]);

        }

    }
}

当我运行此命令时，它会打印出"inloggning.Classname".有人可以帮助我了解为什么以及如何解决此问题，以便打印出"hello"字样.和世界".

when i run this it prints out "inloggning.Classname". Can someone help me understand why and how i can fix it so it prints "hello" and "world".

推荐答案

像这样向您的对象添加toString方法

Add a toString method to your object, like that

public string overide ToString()
{
return hello + " " + world;
}
