Demo Questions

You are developing an application that includes a class named Order. The application will store a collection of Order objects.

The collection must meet the following requirements:

Use strongly typed members.
Process Order objects in first-in-first-out order.
Store values for each Order object.
Use zero-based indices.

You need to use a collection type that meets the requirements.

Which collection type should you use?

Queue<T>
SortedList
LinkedList<T>
HashTable
Array<T>

Correct answer: A

Explanation:

Queues are useful for storing messages in the order they were received for sequential processing. Objects stored in a Queue<T> are inserted at one end and removed from the other. References: http://msdn.microsoft.com/en-us/library/7977ey2c.aspx

You are developing an application. The application calls a method that returns an array of integers named employeeIds. You define an integer variable named employeeIdToRemove and assign a value to it. You declare an array named filteredEmployeeIds.

You have the following requirements:

Remove duplicate integers from the employeeIds array.
Sort the array in order from the highest value to the lowest value.
Remove the integer value stored in the employeeIdToRemove variable from the employeeIds array.

You need to create a LINQ query to meet the requirements.

Which code segment should you use?

Option A
Option B
Option C
Option D

Correct answer: C

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?

Where order.OrderDate.Value != null && order.OrderDate.Value.Year >= year
Where order.OrderDate.Value == null && order.OrderDate.Value.Year == year
Where order.OrderDate.HasValue && order.OrderDate.Value.Year == year
Where order.OrderDate.Value.Year == year

Correct 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

* 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
