sharepoint enterprise – Use CSOM To Pull Date Value From Date And Time Field

Using C# CSOM and this is SharePoint 2010 – I am attempting to pull the vale of a Date And a time field to my Winform.

If I type in the immediate window
listItem(“datetimefield”);

It will return
{7/22/2018 3:22:00 AM}
Date:
Day:
DayOfWeek:
DayOfYear:
Hour:
Kind:
Millisecond:
Minute:
Month:
Seconds:
Ticks:
TimeOfDay:
Year:

I want to pull the value from Date – what would be the syntax to do such?

EDIT
If it helps this is full syntax I attempted to use. I can connect fine and pull values for other field types, just not a Date and Time field type.

Public static void GetDateTimeData()
{
  using (var ctx = new ClientContext(SPURL))
  {
    List list = web.Lists.GetByTitle(SPSite);
    CamlQuery camlQuery = new CamlQuery();
    camlQuery.ViewXml= strong.Format();

    ListItemCollection items = list.GetItems(camlQuery);
    ctx.Load(list);
    ctx.Load(items);
    ctx.ExecuteQuery();

    foreach (ListItem listItem in items)
    {
        DateTime TargetSD = (dateTime)listItem("maindate");
        string date = Convert.ToDateTime(listItem("maindate").ToString();
    }
  }
}
