一周一周来算，注，如果本月1号是星期日，则这一月共有六周，即六行，所以干脆每月都输出6周就行了，然后再算第一周里的本月一号是周几，第一周里本月又占了几天。。。呃。。。反正很乱，想了一上午，现在写出来了倒不知道如何解释了。。算了。。直接上代码。。
//日历界面
public IActionResult RiLi()
{
List<Model.VM_OneDay>[] ss = new List<Model.VM_OneDay>[6];
DateTime nowmonth01 = DateTime.Parse( DateTime.Now.ToString("yyyy-MM-01")); //本月一号
int week01 =(int)nowmonth01.DayOfWeek; //本月一号是周几？
int zhanjitian = 7 - week01; //本月在第一周占了几天，如3月1日是周三，则第一周则占了5天，用于算第2，3，4周
for (int i = 0; i < 6; i++)
{
List<Model.VM_OneDay> aa = new List<Model.VM_OneDay>();
if (i == 0)
{
//第一周
for (int j = 0; j < 7; j++)
{
if (j>=(int)week01)
{
int x = j - week01;
DateTime date = nowmonth01.AddDays(x);
if (x==0)
{
aa.Add(new Model.VM_OneDay() {Date=date, DateStr = date.ToString("M月d日") }); //1号
}
else
{
aa.Add(new Model.VM_OneDay() {Date = date, DateStr = date.Day.ToString() });
}
}
else
{
DateTime date = nowmonth01.AddDays(-(week01-j));
aa.Add(new Model.VM_OneDay() {Date = date, DateStr = date.Day.ToString() });
}
}
}
else
{
for (int j = 0; j < 7; j++)
{
int x = (i - 1) * 7 + zhanjitian + j;
DateTime date = nowmonth01.AddDays(x);
if (date.Day == 1)
{
aa.Add(new Model.VM_OneDay() {Date = date, DateStr = date.ToString("M月d日") });
}
else
{
aa.Add(new Model.VM_OneDay() {Date = date, DateStr = date.Day.ToString() });
}
}
}
ss[i] = aa;
}
ViewBag.data = ss;
return View();
}
