将 DatetimePicker 值插入函数

Question

 private void btntest_Click(object sender, EventArgs e)
    {
        DateTime d = new DateTime(2016,2,13);
        LunarDate ld1 = LunarYearTools.SolarToLunar(d);
        lblamlich.Text = (ld1.ToString());
    }

Note DateTime d = new DateTime(Int year,Int month,Int day)

如何将日期时间选择器的值插入 new DateTime(2016,2,13)？？？我尝试将 datetime 转换为 Int 但它不起作用：

        string a = dateTimePicker1.Value.ToString();
        int b = (int)(a);
        DateTime d = new DateTime(b);
        LunarDate ld1 = LunarYearTools.SolarToLunar(d);
        lblamlich.Text = (ld1.ToString());

Answer 1

如果我没理解错的话，应该是这么简单：

var d = dateTimePicker1.Value;

var newD = new DateTime(d.Year, d.Month, d.Day);

Answer 2

DateTimePicker.Value 属性已经是 DateTime。仅供参考：

DateTime d = dateTimePicker1.Value;

如果您只对日期感兴趣而希望忽略时间，请使用 DateTime.Date 属性:

DateTime d = dateTimePicker1.Value.Date;
