asp dropdownlist-在列表中添加数字1-15

For i As Integer = 1 To 15
    ddlAdults.Items.Add(new ListItem(i.ToString(), i.ToString()))
Next i

ddlAdults.DataSource = Enumerable.Range(1, 15)
ddlAdults.DataBind()

for(int i=0;i<15;i++)
{
   ddlAdults.Items.Insert(i, new ListItem((i+1).toString(), (i+1).toString()));
}

使用循环?

比如for循环或者foreach循环。

//cmbDay.Items.Insert(0, new ListItem("1"));
//cmbDay.Items.Insert(1, new ListItem("2"));
//cmbDay.Items.Insert(2, new ListItem("3"));
//cmbDay.Items.Insert(3, new ListItem("4"));

for( i=0;i<15;i++)
    {
       cmbDay.Items.Insert(i,new ListItem(i.ToString()));
    }
