Answer 1

DateTime sj = DateTime.Now.AddMonths(-6); 月份减
还有天书年什么的 改成+就好了 定好初始时间然后

Answer 2

private void textBox2_TextChanged(object sender, EventArgs e)
{
this.dateTimePicker1.Format = DateTimePickerFormat.Custom;
this.dateTimePicker1.ShowUpDown = true;
this.dateTimePicker1.CustomFormat = "yyyy年MM月dd日";
dateTimePicker1.Text = "";
switch (comboBox2.Text)
{
case "月":
dateTimePicker1.Text = this.dateTimePicker1.Value.AddMonths(int.Parse(textBox2.Text)).ToString();
break;
case "周":
//这里不对。你自己在处理下周的
break;
case "天":
dateTimePicker1.Text = this.dateTimePicker1.Value.AddDays(int.Parse(textBox2.Text)).ToString();
break;
default: break;
}
}
