（上面给的是 我定义的类中的属性，并且已经生成dll文件。从其他程序调用都是没问题的。）
using System;
using System.Collections.Generic;
using System.Text;
using 属性;//已经引用属性库dll文件！

namespace 调用属性程序 //调用属性！
{
   
    class Program
    {
        static void 输入显示员工属性(ref employeeInfo[] empNew)//输入显示函数
        {
            for (int i = 0; i <=empNew.Length - 1; i++)
            {
                Console.WriteLine("第"+(i+1)+"个员工。");
                Console.WriteLine("输入公司名称：");
                empNew[i].employeeCompany = Convert.ToString(Console.ReadLine());//属性的写入（提示出错的地方）
                Console.WriteLine("输入姓名：");
                empNew[i].employeeName = Convert.ToString(Console.ReadLine());//属性的写入
                Console.WriteLine("输入性别：");
                empNew[i].employeeGender = Convert.ToString(Console.ReadLine());//属性的写入
                Console.WriteLine("输入年龄：");
                empNew[i].employeeAge = Convert.ToInt16(Console.ReadLine());//属性的写入
                Console.WriteLine("公司：" + empNew[i].employeeCompany + " 姓名：" + empNew[i].employeeName + " 性别:" + empNew[i].employeeGender + " 年龄：" + empNew[i].employeeAge);
            }
        }

        static void Main(string[] args)
        {            
            Console.Write("输入员工数目：");
            int x = Convert.ToInt16(Console.ReadLine());
            employeeInfo[] empNew = new employeeInfo[x];
            输入显示员工属性(ref empNew);         
            
            Console.ReadKey();
        }
    }

}
运行时提示在               
empNew[i].employeeCompany = Convert.ToString(Console.ReadLine());处提示 “未处理”“未将对象引用设置到对象的实例。”
请教怎样能调试成功。
本人初学者不是很熟悉，  请附上正确代码函数部分代码！
