You are developing an application that uses the Microsoft ADO.NET Entity Framework to retrieve order information from a Microsoft SQL Server database.
The application includes the following code. (Line numbers are included for reference only.)
The application must meet the following requirements:
• Return only orders that have an OrderDate value other than null.
• Return only orders that were placed in the year specified in the OrderDate property or in a later year.
You need to ensure that the application meets the requirements.
Which code segment should you insert at line 08?
A . Where order.OrderDate.Value != null && order.OrderDate.Value.Year > = year
B . Where order.OrderDate.Value = = null && order.OrderDate.Value.Year = = year
C . Where order.OrderDate.HasValue && order.OrderDate.Value.Year = = year
D . Where order.OrderDate.Value.Year = = year
Answer: A
Explanation:
• For the requirement to use an OrderDate value other than null use:
OrderDate.Value != null
• For the requirement to use an OrderDate value for this year or a later year use: OrderDate.Value>= year
