How to set the current time in a DateTimePicker

I am trying to set the current time to a DateTimePicker (with Format Time) like

this.myDateTimePicker.Value = DateTime.Now;

but when executing my code I am getting an exception

Object reference not set to an instance of an object

What I am doing wrong?

Thanks.

If you working with Forms just add DateTimePicker object from Toolbox , and first call InitializeComponent() Or just create new instance in your code

 this.dateTimePicker1 = new System.Windows.Forms.DateTimePicker();

Only after creating instance of an DateTimePicker you can use it:

this.dateTimePicker1 .Value = DateTime.Now;

set this code in your 'form1_Load' event

DateTimePicker dtpPurDate = new DateTimePicker;
dtpPurDate.Text = DateTime.Now.ToShortTimeString();

private void form1_Load(object sender, EventArgs e)
{
     DateTimePicker dtpPurDate = new DateTimePicker;
     dtpPurDate.Text = DateTime.Now.ToShortTimeString();
}

If you use WPF, not WinForms, add this reference:

xmlns:sys="clr-namespace:System;assembly=mscorlib"

Then in XAML DatePicker's code add:

SelectedDate="{x:Static sys:DateTime.Now}"

Declare your DateTimePicker and try it.

DateTimePicker myPicker = new DateTimePicker;
myPicker.Value = DateTime.Now;

Like someone pointed out, put your code before the InitializeComponent() since it's in that part that your DateTimePicker gets initialized.

1 - Delete you control
2 - Re-add it.
3 - Watch where you put your code.

Should work after that since your doing it right on the code part.

You need to put that code after the InitializeComponent() call is made. There is no instance of myDateTimePicker until that point.
