C#简单输出日历的方法

using System;namespace 控制台日历{ class Program {  public static void Main(string[] args)  {   string s = " ";   Console.WriteLine("输入年份：");   int nYear = int.Parse(Console.ReadLine());   Console.WriteLine("输入月份：");   int nMonth = int.Parse(Console.ReadLine());   DateTime day1 = new DateTime(nYear,nMonth,1);   Console.WriteLine("{0}/{1}",day1.Year,day1.Month);   Console.WriteLine("日 一 二 三 四 五 六");   int week1 =(int )day1.DayOfWeek;//获取当年当月1号的星期   //Console.WriteLine("当月一号的星期{0}",week1);   int lastday = day1.AddMonths(1).AddDays(-1).Day; //获取当月的最后一天   for (int i = 0; i < week1; i++)    Console.Write(s);//不能换行输出   for (int i = 1; i <= lastday; i++)   {    Console.Write("{0:00} ", i);//按01 02 输出    if ((i + week1) % 7 == 0)     Console.WriteLine();   }    Console.WriteLine();   Console.Write("Press any key to continue . . . ");   Console.ReadKey(true);  } }}
