Question

C# DateTimePicker 显示值总是变化,如何设置使其固定?

Answer 1

            dateTimePicker1.Value = DateTime.Parse("2001-1-1");

            dateTimePicker2.Value = DateTime.Parse("2001-1-1 17:30:00");

            dateTimePicker2.Format = DateTimePickerFormat.Custom;

            dateTimePicker2.CustomFormat = "yyyy-MM-dd hh:mm:ss";

设定一个初值，就固定了。

Answer 2

放2个dateTimePicke，dtp1:显示年月日,dtp2:显示时分秒
在窗体加载的时候设置默认值，
private void Form1_Load(object sender, EventArgs e)
{
dtp2.Value = Convert.ToDateTime("2013/1/19 23:59:59");
}

Answer 3

dateTimePicker1.Value = DateTime.Parse("1999-9-9");
