How many time you opened the connection, if in a single shot only the whole data will go and sit in database

I'm getting a "CS1061 C# 'object' does not contain a definition for 'Items' and no accessible extension method 'Items' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?)" How do I resolve?
