Problem with MAPIFolder.Items.Restrict(), C#, Outlook 2003 and ear

I want to aquire all items in the folder that starts later than a specified
time. How can I use the Restrict method to achieve this?

In MSDN, there is a VB example:

sFilter = "[LastModificationTime] > '" & Format("1/15/99 3:30pm", "ddddd
h:nn AMPM") & "'"

But how about C#?
I tried using String.Format with the following code but failed:

Outlook.Items appointmentItems;
try
{
string strStartTime = String.Format(startTime.ToString(),
"ddddd h:nn AMPM");
appointmentItems = folder.Items.Restrict("[MessageClass] =
'IPM.Appointment'");
appointmentItems = folder.Items.Restrict("[Start] >= '" +
strStartTime + "'"); //Exception occurred here
}
catch(Exception ex)
{
......
}

I have figured it out myself. Just use:

DateTime.ToString("yyyy-MM-dd HH:mm");
