推荐答案

你需要得到从组合中选择月份为整数值，并根据该值设置日期时间选择器值，例如，如果您选择第3个月

you need to get the selected month from your combo to a integer value and set the datetime picker value based on that, for example if you select 3rd month

int monthvalue =3;

dateTimePicker1.Value = new Date(dateTimePicker1.Value.Year, monthvalue, dateTimePicker1.Value.Day);

如果您需要更改datetimepicker日期，当您从组合框中选择月份时，则可以将上面的代码放在combobox selectedIndexChanged事件中。



将月份数据绑定到组合框，将值成员设置为整数并将成员显示为月份名称，然后您可以将选定的组合框值解析为整数值并将其设置为如上所述的日期时间选择器月。

if you need to change the datetimepicker date, when you select month from from combobox, then you can place above code in the combobox selectedIndexChanged event.

when you bind the month data to combobox, set value member as integer and display member as month name, then you can parse the selected value of combobox to a integer value and set it as datetime picker month as above.

DateTime monthSelect(int month)
        {
           return DateTime.Now.AddMonths(-DateTime.Now.Month).AddMonths(month+1);
        }

   private void comboBox3_SelectedIndexChanged(object sender, EventArgs e)
        {
            dateTimePicker1.Value=monthSelect(comboBox3.SelectedIndex);
        }

您可以使用此方法。

You can use this method.
