如何在 C# 中正确打印列表的内容

Question

I have created a small console application to test some stuff with collections.

My code looks like this:

namespace Collections
{
  class Program
  {
    static void Main(string[] args)
    {
      List<string> cars = new List<string>();

      cars.Add("BMW"); //0
      cars.Add("Tesla"); //1
      //Add Honda here
      cars.Add("Audi"); //2
      cars.Add("Ford"); //3

      cars.Insert(2, "Honda");

      foreach(string car in cars)
      {
        Console.WriteLine(cars);
      }

      //Console.Read();
    }
  }
}

I expect the output to be

BMW
Tesla
Honda
Audi
Ford

But my output actually looks like this

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

But I can't find my mistake here.

Answer 1

You're printing cars - the collection - instead of car - the current iteration. Change it to Console.WriteLine(car); .
