   var upit = (from c in baza.Dnevnik_rada
                        where c.ID_smjena.ToString()==cmbOdabirSmjene.Text 
                        &&  c.Datum.ToString()==(dtpOdabirDatuma.Text +" 0:00:00" ) 
                        select c.ID_radnik);
            MessageBox.Show(upit.FirstOrDefault().ToString());

嗨，你能帮我吗，第一个条件有效，但第二个条件不行。这是比较日期时间的正确方法吗?当我在messagebox中写这两个日期时间时，我可以看到它们是相等的，我不明白为什么它不起作用?返回0。

比较日期时间和日期拾取器

From MSDN(https://msdn.microsoft.com/en-us/library/).

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;
if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";
Console.WriteLine("{0} {1} {2}", date1, relationship, date2);
// The example displays the following output:
//    8/1/2009 12:00:00 AM is earlier than 8/1/2009 12:00:00 PM
