本月周六周日LIST集合
作者:互联网
最近项目中有用到本月所有的周六,周日,特此分享一下!
算法思路:写一个循环,条件为本月开始日期、本月截至日期,通过循环获取第一个周六,加一天就是周日,每增加六天就是下一个周六,依次类推,循环到月末
代码如下:
+ View Code?
//计算本月有哪些天是周六,周日
//本月开始日期
var starMoth = DateTime.Now.AddDays(-DateTime.Now.Day + 1).Date;
//本月截至日期
var stopMoth = starMoth.AddMonths(1).AddDays(-1).Date;
var listSaturday = new List<DateTime>();
var listSunday = new List<DateTime>();
var temp = starMoth;
while (temp <= stopMoth)
{
if (temp.DayOfWeek == DayOfWeek.Saturday && temp <= stopMoth)
{
listSaturday.Add(temp.Date);
if (temp.AddDays(1).Date <= stopMoth)
{
listSunday.Add(temp.AddDays(1));
}
temp = temp.AddDays(6);
}
else
{
temp = temp.AddDays(1);
}
}
Console.WriteLine( "本月周六--" );
listSaturday.ForEach(n => Console.WriteLine(n.Date));
Console.WriteLine( "本月周日--" );
listSunday.ForEach(n => Console.WriteLine(n.Date));
Console.ReadKey();

运行结果:
