我想在下拉列表中显示一周的日期,默认为今天的日期。我怎样才能做到这一点?
我还被告知“使用类DateTime.Now,并将数据值转换为字符串”。
感谢任何帮助!

这适用于我的asp.net项目
DropDownList1.Items.Add(DateTime.Now.ToString());
这个在我的组合框上
comboBox1.Items.Add(DateTime.Now);
我不完全确定你的问题。你想做什么?
for (int i = 0; i < 7; i++)
{
DropDownList1.Items.Add(DateTime.Now.AddDays(-i).ToString());
}

试试这个:
//Get Start And End
int delta = Convert.ToInt32(DateTime.Now.DayOfWeek);
delta = delta == 0 ? delta + 7 : delta;
DateTime moday = DateTime.Now.AddDays(1 - delta);
DateTime sunday = DateTime.Now.AddDays(7 - delta);
//Get Date Range
List<DateTime> allDates = new List<DateTime>();
//Add To Your List
for (DateTime i = moday; i <= sunday; i = i.AddDays(1))
{
DropDownList1.Items.Add(i.Date.DayOfWeek);
}
//Select Today Name
DropDownList1.SelectedItem = DateTime.Today.Date.DayOfWeek;

格式(mm/dd/yyy)
//Add To Your List
for (DateTime i = moday; i <= sunday; i = i.AddDays(1))
{
comboBox1.Items.Add(i.Date.ToShortDateString());
}
//Select Today Date(dd/mm/yyy)
comboBox1.SelectedItem = DateTime.Today.ToShortDateString();

你可以把它放在加载事件
上 protected void Page_Load(object sender, EventArgs e)
{
for (int i = 0; i < 7; i++)
{
DropDownList1.Items.Add(DateTime.Now.AddDays(-i).ToString());
}
}
