有人知道怎么做吗？ [英] Does someone know how to make this?

问题描述

TekstMaker tm = new TekstMaker();
tm.VoegToe("Hallo", 1);
tm.VoegToe("1234567890", 0);

我的尝试：



我试过这个，但它没有做任何事情......

What I have tried:

I have tried this, but it doesn't do anything..

class Program
    {
        public string Voegtoe(string invoertekst, int aantalkeer)
        {
            Console.WriteLine(invoertekst = "");
            return new String('\t', aantalkeer);
        }

        static void Main(string[] args)
        {
            Program tm = new Program();
            tm.Voegtoe("hoi", 5);
            Console.Out.WriteLine();
            Console.ReadLine();
        }
    }
}

推荐答案

你忘了告诉WriteLine写任何东西！添加 tm ：

You forgot to tell WriteLine to write anything! Add tm:

tm.Voegtoe("hoi", 5);
Console.Out.WriteLine(tm);
