本人初学C#，可以说是一窍不通，看着书上弄了一个演示Lock语句实现同步数组的例子，但是运行的时候不出现结果，也不显示任何的错误信息，疑问中。。。。
以下是程序代码段，希望大侠们帮忙啊，55555555555
using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.Threading;
using System.Text;
namespace arraySample
{
    class Program
    {
        static void Main(string[] args)
        {
            string[] csharpBooks = new string[100];
            for (int i = 0; i < 100; i++)
            {
                csharpBooks[i] = "book" + i;            
            }
           OperateArray oparray = new OperateArray(csharpBooks);
            Thread checkArray = new Thread(oparray.CheckArray);
            checkArray.Start();
            Thread setArray = new Thread(oparray.SetArray);
            setArray.Start();
            Console.ReadLine();  
        
        }

    }
    public class OperateArray
    {
        private string[] bookArray;
        public OperateArray(string[] array)
        {
            bookArray = array;
        }
        public void CheckArray()
        {
            lock (bookArray)
            {
               for (int i = 0; i <= bookArray.GetUpperBound(0); i++)
               {
                    if (i > 10 && i / 10 == 0)
                   {
                        Console.WriteLine(bookArray[i]);
                    }
                    else
                    {
                        Console.WriteLine(bookArray[i]+"");
                   }
                }
            }
        }
        public void SetArray()
        {
            lock (bookArray)
            {
                foreach (string bookitem in bookArray)
                {
                    Console.WriteLine(bookitem);
                }
            }
        }
    }
}

你创建项目的时候选择的是windows应用程序，你应该创建控制台应用程序就可以了
