将2D数组从函数转换为main（）中的变量

Question

I am a begginer in C#. I have a problem that can be simply solved by you guys. I have a function that creates 2D array with numbers and returns it. I would like to use this function in main() to get this 2D array in main(). Here is a code that doesn't work (it prints "Y:" only). Could you please help me?

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Simulation
    {

        static int[,] Initialize(int x, int a, int b)
        {
            Random r = new Random();

            int[,] positions = new int[2,x];
            for(int i=0;i<x;i++){
                positions[0,i]=a*r.Next();
                positions[1,i]=b*r.Next();
            }
            return positions;
        }

        static void Main(string[] args)
        {
            int[,] array=Initialize(100,100,100);
            System.Console.WriteLine("Y:", array[1, 1]);
            System.Console.ReadKey();
        }
    }
}

Have a good day!

Answer 1

您的输出行应为：

System.Console.WriteLine("Y: {0}", array[1, 1]);

Answer 2

A small problem at System.Console.WriteLine("Y:", array[1, 1]); line, either use

System.Console.WriteLine("Y: " + array[1, 1]);

or

 System.Console.WriteLine("Y: {0}",  array[1, 1]);
