String was not recognized as a valid DateTime.

هذا هو الكود اتمنى اصلاح الخطا

كود :

' String to DateTime
                Dim MyString As [String]
                MyString = rdlast.Text

                'MyString = "1999-09-01 21:34 p.m.";  //Depends on your regional settings
                Dim mystring2 As [String]
                mystring2 = tblasttime

                Dim MyDateTime As DateTime
                MyDateTime = New DateTime()
                MyDateTime = DateTime.ParseExact(MyString, "yyyy-MM-dd HH:mm tt", Nothing)

                Dim mydatetime2 As DateTime
                mydatetime2 = New DateTime()
                mydatetime2 = DateTime.ParseExact(mystring2, "yyyy-MM-dd HH:mm tt", Nothing)

                '_________________________________________________

                If MyDateTime > mydatetime2 Then
                    Image1.ImageUrl = "~/mgs/on.png"
                Else
                    Image1.ImageUrl = "~/mgs/off.png"
                End If

التنسيق المخزن بالقاعدة والموجود بالمتغيرين mydatetime و mydatetime2

هكذا
