DateTime.Now;
DateTime beginDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
DateTime endDate = beginDate.AddMonths(1).AddDays(-1);

int week = (int)DateTime.Today.DayOfWeek;
if (week == 0) week = 7;
DateTime beginDate = DateTime.Today.AddDays(-(week - 1));
DateTime endDate = beginDate.AddDays(6);

DateTime.Now; 

DateTime beginDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1); 

DateTime endDate = beginDate.AddMonths(1).AddDays(-1); 



int week = (int)DateTime.Today.DayOfWeek; 

if (week == 0) week = 7; 

DateTime  beginDate = DateTime.Today.AddDays(-(week - 1)); 

DateTime  endDate = beginDate.AddDays(6);

不管本日、本周还是本月，都应该是一个时间段，即有begintime和endtime

C# codeprotectedvoid Button1_Click(object sender, EventArgs e)
{string beginTime="",endTime="";switch (RadioButtonList1.SelectedValue)
{//本日时间是从当天00:00:00到23:59:59;case"本日":
beginTime= DateTime.Now.ToString("d")+" 00:00:00";
endTime= DateTime.Now.ToString("d")+" 23:59:59";break;//获取本周时间段,嵌套一个switch语句块,得到本周星期一0点到星期天23点的时间段;case"本周":switch (DateTime.Now.DayOfWeek)// {/*星期一*/case DayOfWeek.Monday:
beginTime= DateTime.Now.ToString("d")+" 00:00:00";
endTime= DateTime.Now.AddDays(6).ToString("d")+" 23:59:59";break;/*星期二*/case DayOfWeek.Tuesday:
beginTime= DateTime.Now.AddDays(-1).ToString("d")+" 00:00:00";
endTime= DateTime.Now.AddDays(5).ToString("d")+" 23:59:59";break;/*星期三*/case DayOfWeek.Wednesday:

endTime= DateTime.Now.AddDays(4).ToString("d")+" 23:59:59";break;//后面周4到周日根据上面计算即可 }break;//获取本月时间段,开始时间是本月1号,而下个月1号减去1天就是本月最后一天;case"本月":
beginTime= DateTime.Now.ToString("yyyy-MM")+"-01 00:00:00";
endTime= DateTime.Parse(DateTime.Now.AddMonths(1).ToString("yyyy-MM")+"-01 00:00:00").AddDays(-1).ToString("d")+" 23:59:59";break;
} Response.Write("选择的时间段是:"+ beginTime+"至"+ endTime);//此时beginTime和endTime还是string类型,转换成DateTime类型传值到数据库即可; }

你要什么形式的结果，DateTime还是string

DateTime dt = DateTime.Now;  //当前时间

 

int dayOfWeek = Convert.ToInt32(dt.DayOfWeek.ToString("d"));



DateTime startWeek = dt.AddDays(1-((dayOfWeek == 0)?7:dayOfWeek));   //本周周一

DateTime endWeek = startWeek.AddDays(6);  //本周周日



 DateTime startMonth = dt.AddDays(1 - dt.Day);  //本月月初

DateTime endMonth = startMonth.AddMonths(1).AddDays(-1);  //本月月末

DateTime.Now;
DateTime beginDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1);
DateTime endDate = beginDate.AddMonths(1).AddDays(-1);

int week = (int)DateTime.Today.DayOfWeek;
if (week == 0) week = 7;
DateTime beginDate = DateTime.Today.AddDays(-(week - 1));
DateTime endDate = beginDate.AddDays(6);
