sharepoint save a date to a date field

Question

How can you save a date in sharepoint programatically?

I have a list with a date field and want to save a date into that field and a regular DateTime field isnt working.

Answer 1

You should be able to save a standard .NET DateTime object into a SPFieldDateTime, like so:

using (SPSite site = new SPSite("http://YOUR URL"))
{
  using (SPWeb web = site.OpenWeb()) 
  {
    SPList list = web.Lists["news"];

    SPListItem item = list.Items.Add();
    DateTime dt = DateTime.Now;

    item["Title"] = "Test";
    item["Expires"] = dt;

    item.Update();
  }
}

Answer 2

you need to convert the date to iso format

myListItem["nameofmydatetimefield"] = SPUtility.CreateISO8601DateTimeFromSystemDateTime(mydatetimeobject);
